I went to university for Engineering, and outside the computer lab we hung out in until 3 AM, there was a huge dewar of liquid nitrogen. I would take that night's empty pop bottle and put in a couple cm of nitrogen and then take it outside - capping it only once we were leaving via the loading bay and setting it down then walking away. A couple of minutes later the pop bottles would rupture, sounding just like a bomb going off halfway across the campus - because that's basically what we'd made. It was incredibly stupid, don't do this. Seriously.
Fucking Ducky😂🤣. Yes I learned a lot about liquid nitrogen. Fuck that shit is cold My imperial banana is now cold. (Shrinkage man) Thanks 😂 I love watching your channel
Grandma Carol loves your videos as do I. A little bit about grandma Carol. She is actually my wife's grandmother who moved in with us when she went blind to the point she had trouble taking care of herself. She turned 91 feb 26 2022. She had never heard of TH-cam until she moved in with us. She finds it amazing the videos I watch. And she loves watching you work and she loves homie even more. So watching a video one day she saw homie open up a package and I said to my wife we should send homie a gift and grandma said yes send it from me so we did. When grandma saw homie open the gift she had the biggest smile I had to play it over and over again she loved it so much. Thank you guys so much for making grandma Carol's birthday.
Karen’s’ photography is so clear and well positioned, the editing so good and Kurtis’s descriptions are so understandable I’m sure these video could be used training. Even if just to show the operators and site mechanics how much damage can be done by not taking proper care. They also show CEE’s customers how much skill, time, equipment and care is invested in their jobs.
Hey Trevor thanks for saying so, it takes a pretty big effort on both our parts (Karen says her job is harder lol) with making these videos and appreciate support and comments like this. Cheers 😎👍
Yes, and even going back to their original posts, the photography was excellent. Curtis' narration has constantly improved with more information and I look forward to every episode.
I’m gonna assume this is another quality production by CEE. (Leaving a comment before I watch the video this time) It’s 10 pm here in North Pole Alaska, like clock work, upload notification came on. Just 30 minutes of a solid production, 30 minutes of excellent craftsmanship, and 30 minutes to escape the worlds problems. Thank you guys for doing what you do, keep killing it.
A few things I've noticed about this channel, first quality work...goes without saying, both the machine work by Kurtis and the recording by Karen are top shelf. Secondly, the viewer learns what the parts that are getting worked on are for and how they are used. Third, The Safety Officer always makes an appearance. Fourth, seeing the bloopers at the end are priceless. Fifth, They are involved with the comments here...means they are paying attention to what's being said and finally, the amount of positive v negative comments...a crapton more positive, means they are doing something right!
That's a pretty great summary of our channel mate thanks for the comment, we think we've got an awesome community of subscribers & viewers here and always appreciate the positive support.
One of the many things I admire about Cutting Edge is that Kurtis and Karen always take safety seriously. So many channels jokingly say “Safety Third”. It’s refreshing to always see safety glasses, crane use to move parts, proper lubrication for safe cuts, etc. When your business is on the line, you don’t take chances. If Kurtis gets hurt, the job doesn’t get done. Losing an eye or worse isn’t good entertainment as far as I’m concerned.
Beautiful job on the repair Curtis! I am still amazed at the line boring machine you have. It makes the setup we used look like stone hammer and chisel work. I froze bushings on heavy equipment along with aircraft parts later on. One night on night shift in the Air Force my guys and gals were welding up parts with all the doors open. It was a beautiful summer night and perfect for work. One of my guys was TIG welding some parts and a bat kept swooping down close enough it was distracting him. He timed it to when the bat swooped down he was going to swat at it. Instead the bat ended up in his glove. Now this was one of our tough guys, lifted weights, ran marathons and went hunting naked with a knife in his teeth. You know the type. When he saw that tiny little bat crawling around on his glove he freaked out and screamed like my 7yo granddaughter! He shook the poor creature off his glove onto the floor and killed it. We always had a cooler full of nitrogen and it was decided while I was on the phone to freeze said bat. About the same time I came out of the office one of the ladies from another shop came in. My guys deemed it necessary to scare her with the bat so tough guy grabs the frosty critter with his pliers and holds it out for it to be seen. A small part of the wing broke off and the rest landed on the floor an shattered into a dozen pieces. Everyone is standing there in shock except me. I just stood there and said, "Guys you better get a broom and dustpan and sweep that thing up before it thaws out or you are going to mop the floor." They swept it up. Homeless was so happy with his ducky he just couldn't control himself......LOL! Karen once again beautiful camera work and editing. You actually got Curtis to smile just a little bit....... Cheers Terry from South Carolina USA
Hey Terry that's one of those stories that sound so crazy you just want to be there to see it 😂 Thanks for sharing gave us a laugh, take care over there mate
A lot of us understand exactly what you're doing, and with your excellent explanations, the reasons you have for how you approach the jobs you undertake. However, many of your loyal viewers, especially here in the USA, have never had the opportunity to learn and perfect the skills needed, or to work with and understand the unique problems associated with the different kinds of equipment you repair on a daily basis. My understanding is that you learned most of your useful skills and repair methods on different jobs repairing a variety of brands & types of heavy equipment, but always wanted to have a one person/ one dog shop and watched the market for the used equipment you needed to become available as other shops either closed down or bought newer equipment. Recognizing the value of the helicopter hanger, with its high and wide doors, and its electric lift in the roof structure, to your planned operation, and being able to negotiate a deal to buy or lease it was genius, as was recognizing the value of the 4 wheel yard tractor/boom lift you had noticed languishing for years in a local field and were able to acquire. Having Karen, the genius videographer, on board has helped potential clients see your attention to detail and your wide knowledge of heavy equipment repair, and what is involved in making a proper repair, including your ability to quickly make new parts to minimize equipment downtime for your clients and save them time and money. But Karen is the person who has encouraged you to continue to make these videos, despite what we learn from your vocabulary lessons, etc., in the out-takes. She has helped you earn a world-wide reputation, and by showing examples of your approach to problems, has encouraged others to set up their own shops when they have the knowledge and skills to succeed, and are ready to make a move. If she has any spare time, video instruction from her would be a great way to help other videographers learn how to do a proper job of understanding and presenting work methods in a variety of shop situations. Keep up the good work, and greetings from another viewer in South Carolina, USA.
Hey mate that's a pretty awesome overview of our history and almost spot on understanding so thanks for watching & supporting for so long to get to know us and our business. Karen said she might make a video one day about her setups and methods etc with video and editing. You South Carolina viewers are some of the kindest people!
I have the same impression as well. It's obvious that besides being a great machinist , he is also a savvy businessman. And it's also obvious Karen has some real video production skills. I dont know if she was trained or not, but she's on a professional level.
I swear,your videos never cease to amaze me. I’m a retired Airline Mechanic and I’ve never seen anyone do the jobs that you do. I thoroughly enjoy watching you do your work. My compliments to you and your lovely wife on the quality of your videos,they are amazingly clear and sharp.👍🏻👍🏻👍🏻
Kurtis for a person who has no formal education I am amazed at your depth of knowledge of metallurgy and mathematics. Your dry humor is very entertaining please keep your videos coming they are very well done. I hear Karen (your boss) in the background guiding you through these videos and she is very entertaining as well. All The Best from Boston Massachusetts
I really love the short lessons on things I have little to no experience in, like handling liquid nitrogen. I don't learn stuff very often in my years in the trades, but when I do, it's absolute platinum!
It is so refreshing to see a younger man like you, Kurtis, being so open minded, willing to try new things and not being afraid to stand up for your convictions. I am thoroughly impressed with your improvisation, skills to think on your feet, size up a list of options and move forward deciding with confidence what to do and a path to do it. I love your channel and look forward to each new video! Best wishes and good health to you your wife and the sweet puppy dog!!
Hi there. Always good to see you doing another skilled job. I guess what I'm impressed with is your canny knowledge of materials and 'process' . This takes you beyond just a good Turner or Welder. You have the expertise to make, mend or create just about anything you turn your hand too. Good on you mate. You're a class act in a world of bullshit baffles brains.
I'm a retired Tool Maker for General Motors Corp. Detroit Diesel . I'm watching from Florida . I have great admiration for your workings and tools. Thank you for being there for us.
Kurtis, I always enjoy watching you even though I am 75 years old you teach me things every time. Thanks! I love hearing your wife giggle every now and then she sounds so sweet.
With an expansion rate from liquid to gas of 600/1, liquid N2 cannot be capped, bottled nor sealed until expansion complete. I have worked in the welding supply industry for 30 years and we had a 10 liter dewar that was returned off rent and wasmissing cap. The dewar was placed at the edge of the doorway of building and water from roof was hitting top of the dewar and creating an ice plug, which once this ice plug sealed the dewar, BOOM. The dewar rocketed out of the storage area and landed about 600 yards away.
Yes, the stories can be very intimidating, but , like using a cutting torch, treat it with respect, you’ll be fine, but take it for granted for one sec, it’ll bite you in the ass. On another liquid gas story, I’ve seen a glove dipped on motor oil then , very carefully, subjected to liquid oxygen explode violently.
@@jeffreyullrich8511 Pressurised Oxygen is also interesting for the same reason as you gave. Do not add lubrication the oxygen bottle of your torch set!
Well done Kurtis & Karen yet another very informative and interesting video. It is especially good to be able to see all of the steps in full from start to finish, the high speed parts are a great help also. I’m sat indoors recovering from a recent heart attack and it is honestly the highlight of my week to watch a new CEE masterclass in machining. Thanks you also for the added spectacle of Homeless and his squeakers. I remember fondly my Staffie from 25 years ago, what characters they are, and possibly one of the friendliest dogs especially with children. Only 6 1/2 days more to wait until next time. 👍
This was one of the best yet. The explanations and video especially the closeups are getting better all the time. The banana was great. When I was younger I worked on a fleet of tractor trailers that used liquid nitrogen for keeping the products cold and being young we did all kinds of stupid stuff with it. However I witnessed a technician get burned badly cause he thought it was too hot outside to wear the protective gear and a blow off valve failed. That sight is in my mind forever, it should be treated with respect. Homeless so excited was great. A happier dog you'll never see.
I appreciate the fact you show what the part does by the clips of the actual machine in operation. It adds a better understanding of how the part was damaged and the steps/tooling needed in the repair.
Hey Kurtis, chemical engineer here, you are absolutly correct about the dewar works, there is a lot of different ways you can transfer "heat" or energy, but what you are mostly interested in here is conduction. Heat is essentially how fast molecules bump into each other, so warm thing, collid often and vice versa. By pulling a vacuum, you remove ""all" the molecules that heat can use to transfer, thereby stopping heating. So it is important to keep it free from holes :) in the bin if there is an air leak, it is far less expensive than the LN costs. To answer your last comment, you will most likely find absolutely nothing inside. The real fun starts when playing with Liquid Helium, that is surrounded by LN and then surrounded by vaccum.
Great content. Good to see that the customer lisrened to the educated advice of one of us that deals with these multi grooved sleeves when that fail. The multi groove sleeve you showed looked like the grooves had been gnawed in by a rabid rate. As always great work behind the camera and the safety officer.
Homeless reaction to the gift from Gma Carol was my first smile of the day! Thank you for that! Love your videos Karen! And you’re pretty good too Kurtis! 😉 A note about liquid nitrogen; my Dermatologist uses it to burn small skin cancers off and it leaves pretty nasty blisters. So just having it splattered on you is going to hurt!
The cool thing about liquid nitrogen is it instantly evaporates, so you can spill it on you with little effect. It's the prolonged +1 second direct contact in the same spot that gets you.
@@VegasEdo yes, it's something I could never try but random splashes have never hurt me(I am an industrial refrigeration mechanic and used it a lot)as long as your hands are DRY. I had to treat a labourer who got too big for his boots and ended up with about three cupfuls down his sleeve- thing about a hot burn is you blister but everything is sterile- with a cold burn you still get all the dead tissue and big blisters but it isn't totally sterile. He fought tissue loss and infection for 18 months. Can be nasty stuff in careless hands.
Interesting use of weld material on getting the old bush out. Nice work on the line bore. With the freezing of the banana should have used the "Banamicromiter" on it to see how much it shrank. Maybe next time. Karen again - great job on the video work. Homeless was to happy to lay down with his chicken, wanted to show it off.
I must be getting old. I thought everyone knew that trick. Good reason to listen to the old codgers yarning. Just for the memories, you can straighten stuff with that trick too.
These videos are extremely satisfying. Not only from getting to watch the process, but by the end I get the sense of accomplishment from a job expertly done as well. Thanks to Kurtis, Karen, and Homey for sharing with all of us. From Detroit Lakes, Minnesota U.S.A.
I must compliment both of you again. Kurtis, your explanations and experience coupled with the calm no compromise attitude you display inspires a great deal of confidence that you are giving the customer the very best repair possible short of buying a brand new part. Karen's ability to frame the shots used in the final videos are just epic and compare with anything I've watched - that includes television shows and motion pictures. I notice the struggle she has getting Kurtis to stand up straight and not lean to one side or the other. She has a gift there is no doubt. Finally, Homeless certainly was on a mission with that duck. What a joy to watch him get excited and then be rewarded with his favorite toy - time to gut another duck! Thanks again for the content - you two have a winning formula!
Fantastic video guys!! Dropping knowledge bombs left and right. The video quality paired with your explanations and workmanship makes these videos really enjoyable to watch.
I just started using liquid nitrogen a few years ago and wished I had discovered it many years ago. Thanks for all the cool videos you do. I've been doing machine work for almost 40 years and still enjoy it every day. I haven't done but very little heavy equipment repairs and enjoy your work. Keep them coming. 😎
I really like that you explained the shrinkage of different materials. Thank you for that! Now I know what I (amateur hobbyist) did wrong with my bushings. It´s ten o'clock in the morning here in Sweden so you are hopefully having a beer after a long week there down under. Cheers! /Jesper
The amount of info as to why and how things fail, why this should be done instead of that tells your customers a whole lot about you and your skills, that makes for a happy customer when the job gets done. The know their part is in good hands and will get it back even better than it was before. For us watching you it tells us just how huge a set of skills you have, your thought processes when fixing a thing and why you do things the way you do. The moment I saw you with the welder to pull the wrecked bushing I knew it was to shrink the remnants of the old one. I'm going to remember that trick. I'm not a metal or wood botherer, not even a fabricator or mechanic. But I have more than a passing interest and I learn a whole lot from watching experts like yourself turn a broken thing into something working. Absolutely awesome video as always, belly rubs for homeless too, hee daft woof
Curtis, your channel should really be required viewing for all undergraduate mechanical engineering courses. It's just full of so many practical engineering design considerations, which you present so well! Thanks for everything.
32:10 Kurtis says "it's not funny, this is not funny". Yes, it was funny. The effort you both put in to properly record what you are going to do is greatly appreciated. Oh, make no mistake, it's not the information that's great, it's the bloopers. And Karen giggling. But Homey and the duck, he stole the spotlight... again!
@@CuttingEdgeEngineering The screw ups show us that you're one of us ordinary humans and that even us ordinary blokes can rise up and make a decent career out of whatever we're good at. You and Karen inspire the rest of us to make something out of our dreams. Y'all show us that it's doable for the rest of us! CEE, the little shop that could! Great work guys! Thank you for continuing to do this stuff! Y'all are much appreciated! :)
The content of your engineering ability, with the description of what and why so that even simple people like me can follow, is always a great watch. Thank you as always for that. I've mentioned before that the out takes are always an entertaining add-on to the production. I'm going back through them to count how many times 'Phuq' is used :-) Thanks for the channel mate. Cheers Pete' N.Z.....that other island.
Hey Pete thanks for the great comment mate, glad the video's are enjoyed over the ditch. When you count the phuqs actually double them, Karen edits out at least half so we don't get TH-cam strikes 😂
@@CuttingEdgeEngineering Hahahaha. Another interesting vid could be you videoing Karen doing machining. Just a thought, but then I am just a Kiwi :-) Cheers Pete'.
And Kurtis can run the camera, I’m sure that would be interesting. When I was farming I tried to do the AI & we used a Dewar similar to your’s when the semen was thawed out worked just fine
Great job! I appreciate the safety instruction, well presented! You probably should add one more caveat: Use in well ventilated areas. Nitrogen might not be dangerous on its own but as it boils off it can displace large amounts of air. Amusingly tall glass thermos flasks are pretty good at storing small quantities of LN2 as they transfer heat even less than metal dewars and the boiled off nitrogen is so cold it will just sit in the neck forming an effective stopper. In our lab we used just a wad of cotton wool as a stopper for them.
Another amazing video! Thank you. I have been in the hospital/rehab clinic for 3 weeks and have gone back and looked a lot of the CEE videos for second or third times. I had a titanium knee installed in my left leg. I had planned on coming to AUS to have the job done by Kurtis, but what with Covid, etc. I had to have it done locally. Thankfully, no welding was required, but otherwise the surgeon seemed to be quite well versed in the use of power tools and equipment. I now have two titanium hips and a titanium knee. My body has definitely gained in monetary value! Thanks to you, Kurtis, Karen and Homey, for making my stay here much less boring. I love your videos.
BRUCE! We noticed your absence and were wondering if you were okay mate. That sounds like a valuable upgrade and good thing you had a surgeon with the right tools and know how to get it done. Hope your recovery continues along and you feel great again soon. Take care!
Your knowledge of these big machines is just insane, its almost as if you've designed all those machines your self. Awesome video's, I love it, good on ya!
@@CuttingEdgeEngineering and that experience is paying off right now. And also, a bit of fun around the workshop is mandatory I'd say, your place appears large enough for some banana hammering haha!
@@CuttingEdgeEngineering I'm curious if you've ever made the mistakes you mention your customers making! I love how you explain how to do it right even when that knowledge is exactly what people are paying you for.
Kurtis, Rest assured, EVERY vidro of yours is educational!! I look forward every Friday, to the next instalment of my education!! Keep doing it mate, we love what you do!👍
Learning something new each week and it's always entertaining. Really gets me thinking that the persons who invented these machines had a seriously big brain.
Love your vides I work at P&W Quality Machine in Texas A 35 year job We do the exact same jobs you do and the same machining techniques We do a lot of Caterpillar parts and Hydraulic cylinder repair stubbing shafts and bearing repair on rod eyes You are a very talented Machinist
I work in an engine factory and we used nitrogen to shrink the pin bushings on the connecting rod when their pressed in. Then we bought a cryogenic freezer that keeps the bushings at -80° F. It's not near as cold as nitrogen but for bronze bushings it's plenty cold enough for pressing into a rod pin bore. As a machine repairman we when we rebuild a spindle we will place the bearings in there the night before and they fall into the bearing bore in the housing. No impact needed at all. We also have an old pizza oven that we will place the cast iron housing into and get it to 400°. Heat/cold is a blessing when you're a repairman
Great content! Glad you showed how cool, potent, and dangerous liquid nitrogen can be when used. The linden (sp?) frost effect, think that's it, will protect people for a few seconds against the freezing effects of liquid nitrogen, however, liquid nitrogen is still no joke. You can make rockets with it by using warm water in a soda bottle and quickly tipping it over, but that's kinda dangerous as it could blow up.
Loved the vid - thanks. Favourite bits were: * Homey being so happy and excited, running round the office with his new ducky 😀 * Putting weld bead on the inside of the old bush - I actually knew what you were doing before you explained it! (thanks to other vids I've watched on TH-cam) * The panning shot from the first bored end to the second - Karen added the sound of the line borer traversing - genius! 👍 All the best, Paul
Love “playing” with LN2. We have some cameras that use it to reduce the thermal noise and electrons captured on the cameras detectors. One camera has a dewar inside of a dewar to get temps down to view Mid to NIR. It’s older technology, but still works. Love seeing it used in other ways.
Love this channel. Kurtis is a first rate professional, and insanely talented. Karen does an outstanding job with filming and editing. I predict this channel will easily surpass 1M subs by year end ‘22.
Thanks, Kurtis, learned a lot about interference fits. Like the way you explain things and why you are doing it. Great video. Ps Stanley my 5-month-old Labrador enjoyed the bit with Homeless and the duck. His head was looking at the screen and moving side to side trying to make out what was happening. Hilarious. All the way from the UK
Another great upload! I see that there is a lot of scrap left on the cutting surface. We used to have so many problems with this on some jobs that we created a constant airflow to keep the cutting surface clean. It's some extra work and setup, but it worked out great. Excellent film work, as always!!
I am a American machinist and tool and die maker and I really enjoy watching you work on your jobs. I always see somthing new or learn things, so thank you! Thank you to the lady who does a great job filming!!! Great channel!
Thanks for an interesting episode! Watching your episodes is like going to a workshop school. Have you gained more customers because they watch your videos and discover your skills and knowledge?
That liquid nitrogen would work brilliantly if you needed to chill a few beers in a hurry.😜Thank you Kurtis for sharing your knowledge with us mere mortals, much appreciated. Awesome camera work and editing Karen, you are truly a natural. Hugs and big kisses to Homey. All the best, take care.
I just copied the transcript over to Word and did a "find" on the word "bush". It counted "bush" being said 44 times. Sorry you had to stay up so long. You can get some sleep now. :D
Hey, i was wondering if you could export your videos to 1440p or 2160p in the future? even if they are recorded at 1080, the increase in bitrate TH-cam uses for the higher resolutions will mean it'll look significantly clearer & i'd really love that Great content still!
May you consider make some vids with 60p or even lower? I like diffuse color patches with no clear boundaries... Though nice content, thanks a lot... Cheers
Hey guys.. thanks for the upload this week..and the informative session on bushes and the pro's and cons re greased/ machine groove bushes.. ah liquid nitrogen...really miss playing with the stuff..in a previous life we used to use it to fit bushes and bearings on F/A-18 Undercarriage legs..fun days.. Once again great video/editing Karen..you make Kurtis look good🤣🤣 Haveagreatweekend team...regards Patchy 🍕🍻🍕🍻 Ps.. next time you use the sir mechanica can you do an info session on it...
Hey Patchy glad you enjoyed this weeks vid, that sounds like something you would not want to F'Up! Yeah we do have a "tour" video of the line borer still on the to do list. Have a good weekend too mate, cheers
Another great job, as usual, Kurtis! And you are right on about the weakening of bushings and pins by grease grooves/holes. Having run and repaired lots of these kinds of units in the Pacific Northwest woods of the US, I know you are speaking the truth. Keep up the great work, enjoy seeing how you approach repairs. After fifty some years around machinery and repairs, I still try to learn something new, and you provide it!
Every time I watch one of your videos I’m blown away by simply how brilliant you are. You seriously know your shit Curtis!! The filming is spot on perfect and of course the insets of homeless and then the out takes at the end bring it all together perfectly, not off by even 0.001 of a mil !!
Awesome! Thanks for taking my suggestion and measuring the change in size when using LN2 and doing it with the brass as well. I will share this with the schools I go to give liquid nitrogen presentations at. I used to do the banana thing but it got tedious always buying bananas. Plus, the students always wanted to eat the -200F banana ahaha. Our main business is a LN2 Ice Cream shop and the science presentations are part of our business model. Of course, the main thing students remember is that we made ice cream 🤣🤣
It's so good how you take time to explain the problem, often what caused it, some different options for repair, and why you chose the way you show us in the video. I often learn more hearing you discuss what you decided against and why, than I do in the actual videos (which I usually learn from and are high very quality). I appreciate your interference fit tips / rules of thumb a lot, I am sure you learned them from experience. Cheers!
I really enjoy watching you and all the information you pass on. I work on a very large farm and have over a hundred pieces of equipment I work on. The equipment varies from the 1940s to current. The issues we have is a lot of the equipment is obsolete and parts are no longer available. So saying that a lot of improvising is performed. To finally be able to learn the different methods you use is worth it’s weight in gold. Thanks again for posting your extreme knowledge of the different topics you cover. You are certainly a professional.
For such a young man , you make everything you do seem like old hat, done it many times. That’s TALENT , pure n simple. Being able to get through a tough job without swearing ? That’s EDITING !! Y’all are rockstars. !!
As has been said the videaography, thanks Karen, is sweet. And Kurtis' expertise, on the job, shines through but what I'm really impressed by is the job information you give. Do 'this' and you'll save time and money. I'd say that quite a few companies wouldnt be as open. A longer job means more money to the company so It wouldn't be in their interest to be as open. It shows that your a genuine and honest guy Kurtis. Impressive and inspiring...
Even a small job for you is big……love the old big equipment you get and restore back to operating condition …….Kudos on the videos informative and very entertaining……the dog is very entertaining…….keep up the good work……..👍👍👍👍👍👍🤔🤔🤔🤔🤔🤔😁😁😁😁😁😁
I am just amazed at the line boring machine/technology. Your descriptions of what has happened to the part and why really helps the viewer understand what you're planning to do. Excellent video by Karen as well. Beautiful country you have there. I spent time there years ago in Surfers to watch an Indy Car Race. Thanks for what you and Karen do.
Good call on that boom. I would every year get one of these booms and their bases on the machine to re-sleeve all the boom base and sticks each year. It always wondered me of that the fact of an operators fear of a grease gun can cause such extensive damage but hey, , , they keep us well paid eh, LOL. You well know how I love that line bar of yours. Still love every time you take it out. I think Mr Safety is in nervana after getting his latest treat. He really is a neat fella eh. I remember one breakup I ran out of any Nitrogen or Co2 so I went around camp and gathered up all the spare fire extinguishers and got the job done. As a bush mechanic we do what we need to do make the equipment get back to work asap eh. I have always stayed at .001 per inch of an interference fit suited the job perfectly. I have never had a failure using that formula. After an extinguisher has been compromised the rest can be used on a hot summers day to cool our day drinks and after hours have a few cool ones, Fosters comes to mind, LOL. Take care mate. You two sure put up some great videos. Take care eh. That banana was major funny you two. Ya have to have some fun every day eh, LOL.
The machining content was great ... but Homeless and the Duck absolutely made a tough day disappear!!! Some days you need a reason to smile, and Homeless being that excited was perfect! Thanks for sharing 🇨🇦
Your description of a dewar was spot-on. As a cryogenic storage professional once told me, nothing insulates quite as well as nothing. :) Also - the CTE for steel is about 11e-6 m-C/m, so assuming you took it down 200 degrees C, you would expect a little over .2 mm on a 95 mm part. Just like you observed. It is always nice when the theory and practice work out. The coefficient of thermal expansion has little to do with density. It is related to the bond energy between the atoms in a material, and so generally most closely related to melting point. For example, magnesium and lead have very similar CTEs, and tungsten has a very low CTE. There are some materials engineered to have virtually no CTE, like Invar 36. It is often used in optical assemblies and was awful to machine (gummy gummy gummy) before a free-machining version became available.
I absolutely LOVE the common sense, no bullsh*t approach to upgrades and modifications! The KISS method! (Keep It Simple Stupid.) It’s effective on soooo many levels. Well done folks! Well done indeed. 😎👍
There’s so much to love about your videos: the dog, obviously, and the way you both do the film and narration together. In this one, it’s fun that you’re repairing yet another thing whose equipment brand you don’t know. The biggest thing, though, is that the videos are all of manual machining; as a hobbyist who doesn’t want to do yet another thing on my computer (CNC) it’s great to see manual machining at the pro level.
Wish you were near me In the USA Kurtis! I would love to be there watching you work! I’m 64 and I always loved machining but never did it myself. I like your work ethic. Keep up the videos
Being a retired machinist myself we would fit speedo bushes into axles for locomotives using a dry ice in a pellet form to shrink down the bush. In all the years I did that job I only ever had to m/c out one bush cause of too much interference. Learnt from that mistake!
I saw my dad removed bushings and bearings races that way he called it welding them out course we're from the south but you do things almost the same way he did is a pleasure watching you in all your little tricks cuz my dad had the same type of tricks be safe have a great day Sam
Fricken frozen bananas!! I knew it was gonna be good when you mentioned LN in your post! I hope that was hard surface welding on the stick and not a “structural” repair! I have a feeling this boom needed more than a re-bush!
Fajną macie tę maszynę Meccanica WS2 i dużą wiedzę w obróbce i naprawie elementów ze stali. Pracuję jako mechanik samochodów ciężarowych i szanuję takich fachowców jak Ty. Zdrowia dla Was. 😊
I have a degree in chemistry, and used liquid nitrogen to run chemical reactions, which is were two chemical are mixed in a liquid, and a day later they have combined to make a new chemical. I have a degree in physics. The physics lab I worked in had liquid helium which was in a bottle suspended in liquid nitrogen. I spent 30 years in a medical research lab, and we had several Dewar's of liquid nitrogen. I am amazed at the explanation Kurtis gave. It was perfect. I have not the slightest quibble with anything he said. Other men in his profession speak of it, with obvious misunderstanding.
the traffic on the way home tonight was very bad having reached home all i could think about was my friday fix of you three repairing something thank you for relieving my stressfull commute and homey was on form poor ducky

Hey mate can u do liquid nitrogen in a bottle I think it will became a great video as the banana one was fun to see
МОЛОДЦЫ)😍🥰
I learn something new every video. I'm not a machinist/welder/dog owner so it's all new to me! But I can drive a fork lift, that's about it.
I went to university for Engineering, and outside the computer lab we hung out in until 3 AM, there was a huge dewar of liquid nitrogen. I would take that night's empty pop bottle and put in a couple cm of nitrogen and then take it outside - capping it only once we were leaving via the loading bay and setting it down then walking away. A couple of minutes later the pop bottles would rupture, sounding just like a bomb going off halfway across the campus - because that's basically what we'd made. It was incredibly stupid, don't do this. Seriously.
Fucking Ducky😂🤣. Yes I learned a lot about liquid nitrogen. Fuck that shit is cold
My imperial banana is now cold. (Shrinkage man) Thanks 😂 I love watching your channel
Grandma Carol loves your videos as do I. A little bit about grandma Carol. She is actually my wife's grandmother who moved in with us when she went blind to the point she had trouble taking care of herself. She turned 91 feb 26 2022. She had never heard of TH-cam until she moved in with us. She finds it amazing the videos I watch. And she loves watching you work and she loves homie even more. So watching a video one day she saw homie open up a package and I said to my wife we should send homie a gift and grandma said yes send it from me so we did. When grandma saw homie open the gift she had the biggest smile I had to play it over and over again she loved it so much. Thank you guys so much for making grandma Carol's birthday.
That is awesome!!!
Karen’s’ photography is so clear and well positioned, the editing so good and Kurtis’s descriptions are so understandable I’m sure these video could be used training. Even if just to show the operators and site mechanics how much damage can be done by not taking proper care. They also show CEE’s customers how much skill, time, equipment and care is invested in their jobs.
And don't forget about the safety officer's unique safety training techniques 🤣
Kurtis's descriptions have to be good, it looks like he says them 1000 times before getting one camera worthy... that or a train shoots by lol
Hey Trevor thanks for saying so, it takes a pretty big effort on both our parts (Karen says her job is harder lol) with making these videos and appreciate support and comments like this. Cheers 😎👍
Yes, and even going back to their original posts, the photography was excellent.
Curtis' narration has constantly improved with more information and I look forward to every episode.
@@JS-th2ho yeah pretty much 🤣🤦♂️Sometimes it takes a few tried before my brain to mouth filter gets it right lol
I’m gonna assume this is another quality production by CEE. (Leaving a comment before I watch the video this time) It’s 10 pm here in North Pole Alaska, like clock work, upload notification came on. Just 30 minutes of a solid production, 30 minutes of excellent craftsmanship, and 30 minutes to escape the worlds problems. Thank you guys for doing what you do, keep killing it.
Hey Cameron, that is late and must be cold where you are watching from! Thanks for taking time to watch and comment we appreciate it
No I don’t, I work for myself as a mobile millwright and I sub out all of the machine work.
Camoron Sady there 2 things you can set your wristwatch setting on.
An clock from switserland and your assumption.
Both are spot on.😉😉
Been to North Pole, AK!😀
Lived in North Pole AK for 12 1/2 yrs, love it up there.
A few things I've noticed about this channel, first quality work...goes without saying, both the machine work by Kurtis and the recording by Karen are top shelf. Secondly, the viewer learns what the parts that are getting worked on are for and how they are used. Third, The Safety Officer always makes an appearance. Fourth, seeing the bloopers at the end are priceless. Fifth, They are involved with the comments here...means they are paying attention to what's being said and finally, the amount of positive v negative comments...a crapton more positive, means they are doing something right!
That's a pretty great summary of our channel mate thanks for the comment, we think we've got an awesome community of subscribers & viewers here and always appreciate the positive support.
This may sound odd but I find myself missing them.. like today. Super wholesome content imo.
Couldn’t agree more.
One of the many things I admire about Cutting Edge is that Kurtis and Karen always take safety seriously. So many channels jokingly say “Safety Third”. It’s refreshing to always see safety glasses, crane use to move parts, proper lubrication for safe cuts, etc.
When your business is on the line, you don’t take chances. If Kurtis gets hurt, the job doesn’t get done. Losing an eye or worse isn’t good entertainment as far as I’m concerned.
Great job Kurtis. I like to see how you repared this part. Greetings from Portugal 🇵🇹
Glad you enjoyed it!
Beautiful job on the repair Curtis! I am still amazed at the line boring machine you have. It makes the setup we used look like stone hammer and chisel work.
I froze bushings on heavy equipment along with aircraft parts later on.
One night on night shift in the Air Force my guys and gals were welding up parts with all the doors open. It was a beautiful summer night and perfect for work.
One of my guys was TIG welding some parts and a bat kept swooping down close enough it was distracting him. He timed it to when the bat swooped down he was going to swat at it. Instead the bat ended up in his glove.
Now this was one of our tough guys, lifted weights, ran marathons and went hunting naked with a knife in his teeth. You know the type.
When he saw that tiny little bat crawling around on his glove he freaked out and screamed like my 7yo granddaughter! He shook the poor creature off his glove onto the floor and killed it.
We always had a cooler full of nitrogen and it was decided while I was on the phone to freeze said bat. About the same time I came out of the office one of the ladies from another shop came in. My guys deemed it necessary to scare her with the bat so tough guy grabs the frosty critter with his pliers and holds it out for it to be seen. A small part of the wing broke off and the rest landed on the floor an shattered into a dozen pieces. Everyone is standing there in shock except me.
I just stood there and said, "Guys you better get a broom and dustpan and sweep that thing up before it thaws out or you are going to mop the floor."
They swept it up.
Homeless was so happy with his ducky he just couldn't control himself......LOL!
Karen once again beautiful camera work and editing. You actually got Curtis to smile just a little bit.......
Cheers
Terry from South Carolina USA
Hey Terry that's one of those stories that sound so crazy you just want to be there to see it 😂 Thanks for sharing gave us a laugh, take care over there mate
A lot of us understand exactly what you're doing, and with your excellent explanations, the reasons you have for how you approach the jobs you undertake. However, many of your loyal viewers, especially here in the USA, have never had the opportunity to learn and perfect the skills needed, or to work with and understand the unique problems associated with the different kinds of equipment you repair on a daily basis. My understanding is that you learned most of your useful skills and repair methods on different jobs repairing a variety of brands & types of heavy equipment, but always wanted to have a one person/ one dog shop and watched the market for the used equipment you needed to become available as other shops either closed down or bought newer equipment. Recognizing the value of the helicopter hanger, with its high and wide doors, and its electric lift in the roof structure, to your planned operation, and being able to negotiate a deal to buy or lease it was genius, as was recognizing the value of the 4 wheel yard tractor/boom lift you had noticed languishing for years in a local field and were able to acquire. Having Karen, the genius videographer, on board has helped potential clients see your attention to detail and your wide knowledge of heavy equipment repair, and what is involved in making a proper repair, including your ability to quickly make new parts to minimize equipment downtime for your clients and save them time and money. But Karen is the person who has encouraged you to continue to make these videos, despite what we learn from your vocabulary lessons, etc., in the out-takes. She has helped you earn a world-wide reputation, and by showing examples of your approach to problems, has encouraged others to set up their own shops when they have the knowledge and skills to succeed, and are ready to make a move.
If she has any spare time, video instruction from her would be a great way to help other videographers learn how to do a proper job of understanding and presenting work methods in a variety of shop situations. Keep up the good work, and greetings from another viewer in South Carolina, USA.
Hey mate that's a pretty awesome overview of our history and almost spot on understanding so thanks for watching & supporting for so long to get to know us and our business. Karen said she might make a video one day about her setups and methods etc with video and editing. You South Carolina viewers are some of the kindest people!
I have the same impression as well. It's obvious that besides being a great machinist , he is also a savvy businessman. And it's also obvious Karen has some real video production skills. I dont know if she was trained or not, but she's on a professional level.
I swear,your videos never cease to amaze me. I’m a retired Airline Mechanic and I’ve never seen anyone do the jobs that you do. I thoroughly enjoy watching you do your work. My compliments to you and your lovely wife on the quality of your videos,they are amazingly clear and sharp.👍🏻👍🏻👍🏻
Wow, thank you!
If you like this guy watch ic weld
Kurtis for a person who has no formal education I am amazed at your depth of knowledge of metallurgy and mathematics. Your dry humor is very entertaining please keep your videos coming they are very well done. I hear Karen (your boss) in the background guiding you through these videos and she is very entertaining as well.
All The Best from Boston Massachusetts
hey Fred thanks for that mate the support is appreciated from us both 👍
I really love the short lessons on things I have little to no experience in, like handling liquid nitrogen. I don't learn stuff very often in my years in the trades, but when I do, it's absolute platinum!
Great to hear!
It is so refreshing to see a younger man like you, Kurtis, being so open minded, willing to try new things and not being afraid to stand up for your convictions. I am thoroughly impressed with your improvisation, skills to think on your feet, size up a list of options and move forward deciding with confidence what to do and a path to do it. I love your channel and look forward to each new video! Best wishes and good health to you your wife and the sweet puppy dog!!
Knowing where your bush starts and where your bush ends sounds more like a personal grooming tip then a industrial repair tip. Lol
plenty of double entendre's in this video 🤣👍
You know, oversize bushes were the in thing back in the 70's!
Checking the grease groove for the bush. How he says that with a straight face!! 😂🤣🤘😎
If you trim your bus your deck looks bigger
Personally, I’ve always loved an oversized bush. Probably TMI but it is what it is.
Karen: leading with Homie at the beginning of every video is genius. Makes me smile every time. Thanks.
it is a fortunate customer that hooks up with this fella. the amount of things he's seen in his years of heavy equipment repair is priceless.
Hi there. Always good to see you doing another skilled job. I guess what I'm impressed with is your canny knowledge of materials and 'process' . This takes you beyond just a good Turner or Welder. You have the expertise to make, mend or create just about anything you turn your hand too. Good on you mate. You're a class act in a world of bullshit baffles brains.
Hey Mark cheers mate appreciate the comment 👍
@@CuttingEdgeEngineering Your knowledge and skill are OMG THERE'S HOMELESS !!! WHOOZE A GOOD PUPPY DAWG ?!!!
@@mars6433 😁👍
This was another gem to watch, you guys! Thanks Kurtis, Karen, Homeless, Ducky and Karl - the Man Who Isn't There.
Good old Karl, good memories!
I'm a retired Tool Maker for General Motors Corp. Detroit Diesel .
I'm watching from Florida .
I have great admiration for your workings and tools.
Thank you for being there for us.
Kurtis, I always enjoy watching you even though I am 75 years old you teach me things every time. Thanks! I love hearing your wife giggle every now and then she sounds so sweet.
With an expansion rate from liquid to gas of 600/1, liquid N2 cannot be capped, bottled nor sealed until expansion complete. I have worked in the welding supply industry for 30 years and we had a 10 liter dewar that was returned off rent and wasmissing cap. The dewar was placed at the edge of the doorway of building and water from roof was hitting top of the dewar and creating an ice plug, which once this ice plug sealed the dewar, BOOM. The dewar rocketed out of the storage area and landed about 600 yards away.
damn the stories coming through in the comments about LN2 are crazy 😂👍
Now that would be something terrifying to see! Students always ask me to cap my dewar vent...if they only knew!
Yes, the stories can be very intimidating, but , like using a cutting torch, treat it with respect, you’ll be fine, but take it for granted for one sec, it’ll bite you in the ass. On another liquid gas story, I’ve seen a glove dipped on motor oil then , very carefully, subjected to liquid oxygen explode violently.
@@jeffreyullrich8511 Pressurised Oxygen is also interesting for the same reason as you gave. Do not add lubrication the oxygen bottle of your torch set!
Well done Kurtis & Karen yet another very informative and interesting video. It is especially good to be able to see all of the steps in full from start to finish, the high speed parts are a great help also. I’m sat indoors recovering from a recent heart attack and it is honestly the highlight of my week to watch a new CEE masterclass in machining. Thanks you also for the added spectacle of Homeless and his squeakers. I remember fondly my Staffie from 25 years ago, what characters they are, and possibly one of the friendliest dogs especially with children. Only 6 1/2 days more to wait until next time. 👍
Hey Simon hope you keep resting and recovering there mate, glad you enjoyed the vid 😎👍
This was one of the best yet. The explanations and video especially the closeups are getting better all the time. The banana was great. When I was younger I worked on a fleet of tractor trailers that used liquid nitrogen for keeping the products cold and being young we did all kinds of stupid stuff with it. However I witnessed a technician get burned badly cause he thought it was too hot outside to wear the protective gear and a blow off valve failed. That sight is in my mind forever, it should be treated with respect. Homeless so excited was great. A happier dog you'll never see.
When that pop off blew, oh golly, that was ugly
right on mate, thanks for watching and commenting!
I appreciate the fact you show what the part does by the clips of the actual machine in operation. It adds a better understanding of how the part was damaged and the steps/tooling needed in the repair.
Hey Kurtis, chemical engineer here, you are absolutly correct about the dewar works, there is a lot of different ways you can transfer "heat" or energy, but what you are mostly interested in here is conduction. Heat is essentially how fast molecules bump into each other, so warm thing, collid often and vice versa. By pulling a vacuum, you remove ""all" the molecules that heat can use to transfer, thereby stopping heating. So it is important to keep it free from holes :) in the bin if there is an air leak, it is far less expensive than the LN costs. To answer your last comment, you will most likely find absolutely nothing inside. The real fun starts when playing with Liquid Helium, that is surrounded by LN and then surrounded by vaccum.
Great content. Good to see that the customer lisrened to the educated advice of one of us that deals with these multi grooved sleeves when that fail. The multi groove sleeve you showed looked like the grooves had been gnawed in by a rabid rate. As always great work behind the camera and the safety officer.
hey mate yeah was glad they went with the different bushing on this one. Thanks for watching 👍
Homeless reaction to the gift from Gma Carol was my first smile of the day! Thank you for that! Love your videos Karen! And you’re pretty good too Kurtis! 😉
A note about liquid nitrogen; my Dermatologist uses it to burn small skin cancers off and it leaves pretty nasty blisters. So just having it splattered on you is going to hurt!
We reckon the world needs more smiles and good news lately so glad you enjoyed the video mate
The cool thing about liquid nitrogen is it instantly evaporates, so you can spill it on you with little effect. It's the prolonged +1 second direct contact in the same spot that gets you.
@@VegasEdo I never thought about that, but it’s absolutely how he applies it!
@@VegasEdo yes you are correct. a youtuber bust the myth by splashing a cup full of it directly into his face. The king of random is the channel.
@@VegasEdo yes, it's something I could never try but random splashes have never hurt me(I am an industrial refrigeration mechanic and used it a lot)as long as your hands are DRY. I had to treat a labourer who got too big for his boots and ended up with about three cupfuls down his sleeve- thing about a hot burn is you blister but everything is sterile- with a cold burn you still get all the dead tissue and big blisters but it isn't totally sterile. He fought tissue loss and infection for 18 months. Can be nasty stuff in careless hands.
Interesting use of weld material on getting the old bush out. Nice work on the line bore. With the freezing of the banana should have used the "Banamicromiter" on it to see how much it shrank. Maybe next time.
Karen again - great job on the video work.
Homeless was to happy to lay down with his chicken, wanted to show it off.
I must be getting old. I thought everyone knew that trick. Good reason to listen to the old codgers yarning. Just for the memories, you can straighten stuff with that trick too.
These videos are extremely satisfying. Not only from getting to watch the process, but by the end I get the sense of accomplishment from a job expertly done as well. Thanks to Kurtis, Karen, and Homey for sharing with all of us. From Detroit Lakes, Minnesota U.S.A.
Glad you enjoy it!
I must compliment both of you again. Kurtis, your explanations and experience coupled with the calm no compromise attitude you display inspires a great deal of confidence that you are giving the customer the very best repair possible short of buying a brand new part. Karen's ability to frame the shots used in the final videos are just epic and compare with anything I've watched - that includes television shows and motion pictures. I notice the struggle she has getting Kurtis to stand up straight and not lean to one side or the other. She has a gift there is no doubt. Finally, Homeless certainly was on a mission with that duck. What a joy to watch him get excited and then be rewarded with his favorite toy - time to gut another duck!
Thanks again for the content - you two have a winning formula!
Fantastic video guys!!
Dropping knowledge bombs left and right.
The video quality paired with your explanations and workmanship makes these videos really enjoyable to watch.
I just started using liquid nitrogen a few years ago and wished I had discovered it many years ago. Thanks for all the cool videos you do. I've been doing machine work for almost 40 years and still enjoy it every day. I haven't done but very little heavy equipment repairs and enjoy your work. Keep them coming. 😎
I really like that you explained the shrinkage of different materials. Thank you for that! Now I know what I (amateur hobbyist) did wrong with my bushings. It´s ten o'clock in the morning here in Sweden so you are hopefully having a beer after a long week there down under. Cheers! /Jesper
Good morning to you mate glad you enjoyed that and learned something out of it
The amount of info as to why and how things fail, why this should be done instead of that tells your customers a whole lot about you and your skills, that makes for a happy customer when the job gets done. The know their part is in good hands and will get it back even better than it was before.
For us watching you it tells us just how huge a set of skills you have, your thought processes when fixing a thing and why you do things the way you do. The moment I saw you with the welder to pull the wrecked bushing I knew it was to shrink the remnants of the old one. I'm going to remember that trick.
I'm not a metal or wood botherer, not even a fabricator or mechanic. But I have more than a passing interest and I learn a whole lot from watching experts like yourself turn a broken thing into something working.
Absolutely awesome video as always, belly rubs for homeless too, hee daft woof
Curtis, your channel should really be required viewing for all undergraduate mechanical engineering courses. It's just full of so many practical engineering design considerations, which you present so well!
Thanks for everything.
32:10 Kurtis says "it's not funny, this is not funny". Yes, it was funny. The effort you both put in to properly record what you are going to do is greatly appreciated. Oh, make no mistake, it's not the information that's great, it's the bloopers. And Karen giggling. But Homey and the duck, he stole the spotlight... again!
entertaining the world one fuck up at a time 😂👍
@@CuttingEdgeEngineering - In this video it was one duck and one fuck at a time.
@@CuttingEdgeEngineering The screw ups show us that you're one of us ordinary humans and that even us ordinary blokes can rise up and make a decent career out of whatever we're good at.
You and Karen inspire the rest of us to make something out of our dreams. Y'all show us that it's doable for the rest of us!
CEE, the little shop that could!
Great work guys! Thank you for continuing to do this stuff!
Y'all are much appreciated! :)
The content of your engineering ability, with the description of what and why so that even simple people like me can follow, is always a great watch. Thank you as always for that. I've mentioned before that the out takes are always an entertaining add-on to the production. I'm going back through them to count how many times 'Phuq' is used :-)
Thanks for the channel mate.
Cheers
Pete' N.Z.....that other island.
Hey Pete thanks for the great comment mate, glad the video's are enjoyed over the ditch. When you count the phuqs actually double them, Karen edits out at least half so we don't get TH-cam strikes 😂
@@CuttingEdgeEngineering Hahahaha. Another interesting vid could be you videoing Karen doing machining. Just a thought, but then I am just a Kiwi :-)
Cheers
Pete'.
@@Bristoll170 second that!
And Kurtis can run the camera, I’m sure that would be interesting.
When I was farming I tried to do the AI & we used a Dewar similar to your’s when the semen was thawed out worked just fine
Great job! I appreciate the safety instruction, well presented! You probably should add one more caveat: Use in well ventilated areas. Nitrogen might not be dangerous on its own but as it boils off it can displace large amounts of air.
Amusingly tall glass thermos flasks are pretty good at storing small quantities of LN2 as they transfer heat even less than metal dewars and the boiled off nitrogen is so cold it will just sit in the neck forming an effective stopper. In our lab we used just a wad of cotton wool as a stopper for them.
Another amazing video! Thank you. I have been in the hospital/rehab clinic for 3 weeks and have gone back and looked a lot of the CEE videos for second or third times. I had a titanium knee installed in my left leg. I had planned on coming to AUS to have the job done by Kurtis, but what with Covid, etc. I had to have it done locally. Thankfully, no welding was required, but otherwise the surgeon seemed to be quite well versed in the use of power tools and equipment. I now have two titanium hips and a titanium knee. My body has definitely gained in monetary value! Thanks to you, Kurtis, Karen and Homey, for making my stay here much less boring. I love your videos.
BRUCE! We noticed your absence and were wondering if you were okay mate. That sounds like a valuable upgrade and good thing you had a surgeon with the right tools and know how to get it done. Hope your recovery continues along and you feel great again soon. Take care!
@@CuttingEdgeEngineering Thanks so much, Karen and Kurtis. I'm getting better by the day.
Kurtis is a great teacher in his trade. These hints although short, share so much knowledge about the job.
Your knowledge of these big machines is just insane, its almost as if you've designed all those machines your self. Awesome video's, I love it, good on ya!
had my fair share of experience not only operating but repairing them
@@CuttingEdgeEngineering and that experience is paying off right now. And also, a bit of fun around the workshop is mandatory I'd say, your place appears large enough for some banana hammering haha!
@@CuttingEdgeEngineering I'm curious if you've ever made the mistakes you mention your customers making! I love how you explain how to do it right even when that knowledge is exactly what people are paying you for.
Kurtis,
Rest assured, EVERY vidro of yours is educational!! I look forward every Friday, to the next instalment of my education!! Keep doing it mate, we love what you do!👍
awesome mate appreciate that support!
Learning something new each week and it's always entertaining. Really gets me thinking that the persons who invented these machines had a seriously big brain.
yeah it's pretty crazy what humans have invented over time
Love your vides I work at P&W Quality Machine in Texas A 35 year job We do the exact same jobs you do and the same machining techniques We do a lot of Caterpillar parts and Hydraulic cylinder repair stubbing shafts and bearing repair on rod eyes You are a very talented Machinist
Awesome mate respect to you!
I work in an engine factory and we used nitrogen to shrink the pin bushings on the connecting rod when their pressed in. Then we bought a cryogenic freezer that keeps the bushings at -80° F. It's not near as cold as nitrogen but for bronze bushings it's plenty cold enough for pressing into a rod pin bore. As a machine repairman we when we rebuild a spindle we will place the bearings in there the night before and they fall into the bearing bore in the housing. No impact needed at all. We also have an old pizza oven that we will place the cast iron housing into and get it to 400°. Heat/cold is a blessing when you're a repairman
Thanks for the class on liquid nitrogen I really like it. I never get tired of the quality of work that you do.
Thanks for watching glad you enjoyed it 😎👍
Great content! Glad you showed how cool, potent, and dangerous liquid nitrogen can be when used. The linden (sp?) frost effect, think that's it, will protect people for a few seconds against the freezing effects of liquid nitrogen, however, liquid nitrogen is still no joke.
You can make rockets with it by using warm water in a soda bottle and quickly tipping it over, but that's kinda dangerous as it could blow up.
Loved the vid - thanks. Favourite bits were:
* Homey being so happy and excited, running round the office with his new ducky 😀
* Putting weld bead on the inside of the old bush - I actually knew what you were doing before you explained it! (thanks to other vids I've watched on TH-cam)
* The panning shot from the first bored end to the second - Karen added the sound of the line borer traversing - genius! 👍
All the best,
Paul
Awesome Paul the only thing missing was measuring the banana shrinkage using our awesome banana calipers 😂👍
@@CuttingEdgeEngineering I'm working on something else 🤔 - keep a look out for the mail in a few weeks 📬
Welding to shrink that bushing is genius. The mark of undeniable expertise. Well done.
Love “playing” with LN2. We have some cameras that use it to reduce the thermal noise and electrons captured on the cameras detectors. One camera has a dewar inside of a dewar to get temps down to view Mid to NIR. It’s older technology, but still works. Love seeing it used in other ways.
Love this channel. Kurtis is a first rate professional, and insanely talented. Karen does an outstanding job with filming and editing. I predict this channel will easily surpass 1M subs by year end ‘22.
Thanks, Kurtis, learned a lot about interference fits. Like the way you explain things and why you are doing it. Great video. Ps Stanley my 5-month-old Labrador enjoyed the bit with Homeless and the duck. His head was looking at the screen and moving side to side trying to make out what was happening. Hilarious. All the way from the UK
Another great upload! I see that there is a lot of scrap left on the cutting surface. We used to have so many problems with this on some jobs that we created a constant airflow to keep the cutting surface clean. It's some extra work and setup, but it worked out great. Excellent film work, as always!!
Assuming “scrape” is autocorrect for scrap or swarf?
@@asw19B100 Thank you, you're right, a slip of the pen on my part
My grandfather ran a horizontal boring mill for 43 years back in the early 1900s. Through you, I am learning some of the things he did. Thanks 🙏!
I am a American machinist and tool and die maker and I really enjoy watching you work on your jobs. I always see somthing new or learn things, so thank you! Thank you to the lady who does a great job filming!!! Great channel!
Отличная работа!
"One of the other COOL things about LN2 dewars..." - Comment of the century, right there @21.15. Yesssssss!
Thanks for an interesting episode! Watching your episodes is like going to a workshop school. Have you gained more customers because they watch your videos and discover your skills and knowledge?
Hey mate glad you enjoyed it, yeah we have picked up a few new customers because of the channel
Something about bringing machines back to life that’s beyond rewarding.
That liquid nitrogen would work brilliantly if you needed to chill a few beers in a hurry.😜Thank you Kurtis for sharing your knowledge with us mere mortals, much appreciated. Awesome camera work and editing Karen, you are truly a natural. Hugs and big kisses to Homey. All the best, take care.
Now I’m going to have to watch the video a couple more times…. I just won’t be able to go to sleep until I count how many times Curtis said BUSH
I just copied the transcript over to Word and did a "find" on the word "bush". It counted "bush" being said 44 times. Sorry you had to stay up so long. You can get some sleep now. :D
Hey, i was wondering if you could export your videos to 1440p or 2160p in the future? even if they are recorded at 1080, the increase in bitrate TH-cam uses for the higher resolutions will mean it'll look significantly clearer & i'd really love that
Great content still!
hi nordern
Well hello there Nordern
hi Nordern thanks for the feedback I can definitely look into doing that for future uploads! 😊 Karen
May you consider make some vids with 60p or even lower? I like diffuse color patches with no clear boundaries... Though nice content, thanks a lot... Cheers

ah liquid nitrogen...really miss playing with the stuff..in a previous life we used to use it to fit bushes and bearings on
F/A-18 Undercarriage legs..fun days..
Once again great video/editing Karen..you make Kurtis look good🤣🤣
Haveagreatweekend team...regards Patchy 🍕🍻🍕🍻
Ps.. next time you use the sir mechanica can you do an info session on it...
Hey Patchy glad you enjoyed this weeks vid, that sounds like something you would not want to F'Up! Yeah we do have a "tour" video of the line borer still on the to do list. Have a good weekend too mate, cheers
Karen does some great shots and editing alright.
Another great job, as usual, Kurtis! And you are right on about the weakening of bushings and pins by grease grooves/holes. Having run and repaired lots of these kinds of units in the Pacific Northwest woods of the US, I know you are speaking the truth. Keep up the great work, enjoy seeing how you approach repairs. After fifty some years around machinery and repairs, I still try to learn something new, and you provide it!
Every time I watch one of your videos I’m blown away by simply how brilliant you are. You seriously know your shit Curtis!! The filming is spot on perfect and of course the insets of homeless and then the out takes at the end bring it all together perfectly, not off by even 0.001 of a mil !!
Awesome! Thanks for taking my suggestion and measuring the change in size when using LN2 and doing it with the brass as well. I will share this with the schools I go to give liquid nitrogen presentations at. I used to do the banana thing but it got tedious always buying bananas. Plus, the students always wanted to eat the -200F banana ahaha. Our main business is a LN2 Ice Cream shop and the science presentations are part of our business model. Of course, the main thing students remember is that we made ice cream 🤣🤣
Having some kid eat a -200F banana, I'd hate to explain that to the insurance adjustor.
Nice to wake up to this. Might seem like a daft question but do snap gauges have any form of calibration or testing?
hey mate no calibration needed on them, we are using a calibrated instrument to measure the snap gauge instead 😅
It's so good how you take time to explain the problem, often what caused it, some different options for repair, and why you chose the way you show us in the video. I often learn more hearing you discuss what you decided against and why, than I do in the actual videos (which I usually learn from and are high very quality). I appreciate your interference fit tips / rules of thumb a lot, I am sure you learned them from experience. Cheers!
I really enjoy watching you and all the information you pass on. I work on a very large farm and have over a hundred pieces of equipment I work on. The equipment varies from the 1940s to current. The issues we have is a lot of the equipment is obsolete and parts are no longer available. So saying that a lot of improvising is performed. To finally be able to learn the different methods you use is worth it’s weight in gold. Thanks again for posting your extreme knowledge of the different topics you cover. You are certainly a professional.
For such a young man , you make everything you do seem like old hat, done it many times. That’s TALENT , pure n simple. Being able to get through a tough job without swearing ? That’s EDITING !!
Y’all are rockstars. !!
Thank you so much. Kurtises out takes are pure Australian gold😂😂😂❤❤❤
As has been said the videaography, thanks Karen, is sweet. And Kurtis' expertise, on the job, shines through but what I'm really impressed by is the job information you give. Do 'this' and you'll save time and money. I'd say that quite a few companies wouldnt be as open. A longer job means more money to the company so It wouldn't be in their interest to be as open. It shows that your a genuine and honest guy Kurtis. Impressive and inspiring...
Even a small job for you is big……love the old big equipment you get and restore back to operating condition …….Kudos on the videos informative and very entertaining……the dog is very entertaining…….keep up the good work……..👍👍👍👍👍👍🤔🤔🤔🤔🤔🤔😁😁😁😁😁😁
I must confess this is the first time I've ever seen align boring done in essence in the field. Pretty neat!
I am just amazed at the line boring machine/technology. Your descriptions of what has happened to the part and why really helps the viewer understand what you're planning to do. Excellent video by Karen as well. Beautiful country you have there. I spent time there years ago in Surfers to watch an Indy Car Race. Thanks for what you and Karen do.
You have some amazing equipment I've never seen before.
Good call on that boom. I would every year get one of these booms and their bases on the machine to re-sleeve all the boom base and sticks each year. It always wondered me of that the fact of an operators fear of a grease gun can cause such extensive damage but hey, , , they keep us well paid eh, LOL. You well know how I love that line bar of yours. Still love every time you take it out. I think Mr Safety is in nervana after getting his latest treat. He really is a neat fella eh. I remember one breakup I ran out of any Nitrogen or Co2 so I went around camp and gathered up all the spare fire extinguishers and got the job done. As a bush mechanic we do what we need to do make the equipment get back to work asap eh. I have always stayed at .001 per inch of an interference fit suited the job perfectly. I have never had a failure using that formula. After an extinguisher has been compromised the rest can be used on a hot summers day to cool our day drinks and after hours have a few cool ones, Fosters comes to mind, LOL. Take care mate. You two sure put up some great videos. Take care eh. That banana was major funny you two. Ya have to have some fun every day eh, LOL.
The machining content was great ... but Homeless and the Duck absolutely made a tough day disappear!!! Some days you need a reason to smile, and Homeless being that excited was perfect!
Thanks for sharing 🇨🇦
This is one of the best warning to liquid Nitrogen I have seen by far. big up on that honestly.
Your description of a dewar was spot-on. As a cryogenic storage professional once told me, nothing insulates quite as well as nothing. :)
Also - the CTE for steel is about 11e-6 m-C/m, so assuming you took it down 200 degrees C, you would expect a little over .2 mm on a 95 mm part. Just like you observed. It is always nice when the theory and practice work out.
The coefficient of thermal expansion has little to do with density. It is related to the bond energy between the atoms in a material, and so generally most closely related to melting point. For example, magnesium and lead have very similar CTEs, and tungsten has a very low CTE.
There are some materials engineered to have virtually no CTE, like Invar 36. It is often used in optical assemblies and was awful to machine (gummy gummy gummy) before a free-machining version became available.
I absolutely LOVE the common sense, no bullsh*t approach to upgrades and modifications!
The KISS method!
(Keep It Simple Stupid.)
It’s effective on soooo many levels.
Well done folks! Well done indeed.
😎👍
There’s so much to love about your videos: the dog, obviously, and the way you both do the film and narration together. In this one, it’s fun that you’re repairing yet another thing whose equipment brand you don’t know. The biggest thing, though, is that the videos are all of manual machining; as a hobbyist who doesn’t want to do yet another thing on my computer (CNC) it’s great to see manual machining at the pro level.
Wish you were near me In the USA Kurtis! I would love to be there watching you work! I’m 64 and I always loved machining but never did it myself. I like your work ethic. Keep up the videos
Being a retired machinist myself we would fit speedo bushes into axles for locomotives using a dry ice in a pellet form to shrink down the bush. In all the years I did that job I only ever had to m/c out one bush cause of too much interference. Learnt from that mistake!
I love when during a long technical explanation, I can picture in my mind how many hilarious throw-away takes I'll get to see at the end of the video.
I saw my dad removed bushings and bearings races that way he called it welding them out course we're from the south but you do things almost the same way he did is a pleasure watching you in all your little tricks cuz my dad had the same type of tricks be safe have a great day Sam
とても尊敬しています。いつもWSの使い方を貴方の動画を見て勉強しています。
Fricken frozen bananas!! I knew it was gonna be good when you mentioned LN in your post! I hope that was hard surface welding on the stick and not a “structural” repair! I have a feeling this boom needed more than a re-bush!
Poor ducky is this video’s unsung hero… Great explanations on nitrogen shrinking and related engineering ! Keep on, guys !
I think the "boring process" is the most exciting part! Thank you for the great videos!
Fajną macie tę maszynę Meccanica WS2 i dużą wiedzę w obróbce i naprawie elementów ze stali. Pracuję jako mechanik samochodów ciężarowych i szanuję takich fachowców jak Ty. Zdrowia dla Was. 😊
Homeless's antic were a riot! That poor rubber duck was screaming for mercy. Thanks for posting, as usual - top class. 😎👍😎👍😎👍
can you imagine how cool a high school/college shop class would have be, with Kurtis as the teacher!
I haven’t seen that cool portable boring machine before. That’s awesome. Thanks for entertaining us.
That line boring machine is awesome. Never seen one before, and what an essential piece of machinery. Cheers
I have a degree in chemistry, and used liquid nitrogen to run chemical reactions, which is were two chemical are mixed in a liquid, and a day later they have combined to make a new chemical. I have a degree in physics. The physics lab I worked in had liquid helium which was in a bottle suspended in liquid nitrogen. I spent 30 years in a medical research lab, and we had several Dewar's of liquid nitrogen. I am amazed at the explanation Kurtis gave. It was perfect. I have not the slightest quibble with anything he said. Other men in his profession speak of it, with obvious misunderstanding.
the traffic on the way home tonight was very bad having reached home all i could think about was my friday fix of you three repairing something thank you for relieving my stressfull commute and homey was on form poor ducky
argh traffic congestion is the worst! Have a good weekend mate
I gotta say the pitty is the star of this show! I love seeing a happy pup and skills!
Regardless of how many times I watch this type of content it still fascinates me.
I admire the quality of your work Kurtis,Also the pride you take in it.
