Making a 100T Heavy Duty Mining Jack Cylinder Rod | Machining & Threading
ฝัง
- เผยแพร่เมื่อ 3 ส.ค. 2023
- This video is a job we did to make a new cylinder rod for a 100 Tonne Edmo heavy duty hydraulic jack that is used to lift mining trucks and excavators. The rod has scratches and dents in the chrome and the top of the cylinder rod is damaged. This shows the step by step process to make the new cylinder rod including machining and thread cutting. To start, we remove the piston off the rod and that will be used to test the thread on the new rod. We machine up the new cylinder rod using a 6” inch diameter induction hardened chrome bar. We need to machine both ends of the cylinder rod, the first end we drill and bore the hole to suit the load cap. Then we machine the other end of the rod by machining through the induction hardened chrome layer before turning down the OD and cutting the 8tpi external thread for the piston. We finish the job by installing the piston before drilling and tapping a hole for a grub screw to lock the piston on the cylinder rod.
In this video we are using:
- Hafco TM-26120G Centre Lathe
- MetalMaster HPM-150T Hydraulic Press

Thank god... That was the longest week of my life lol
Hello Karen and Kurtis....hope your short break was fun.
so good to see you back with new videos at 3 am here
in the Other Sunshine State.....
Enjoy the full Moon this weekend,
It is the Blue Moon I heard.....
as always, sending you best wishes,
Paul
Recharging equipment batteries is important sure, Recharging your own, absolutely priceless. Cheers guys.
@3:30 you were both expecting a struggle lol. that "oh" as it just came off easy.
Wonderful to see you back 🙂
CEE has to be one of the most productive and successful 2 person work company on earth. These videos are so well done!
You forgot to include the safety operator Homie.
@@armandhammer9617 your right! I can’t believe I didn’t add homie. Make it a company of 3
@@armandhammer9617 what about George and George and George?
I wonder what the suppliers of the raw materials are thinking... it must be a 10-20 people company to process so much.
And somehow they manage to get a lot of machining done in between all the videoing. 😜
I'd hardly use the word "cheap" to describe your craftsmanship, Curtis. "More affordable" may be a better way to describe it. You guys are extremely valuable in your workmanship all the way to how you make your parts, handle your shop and even make the videos! Glad to have you guys back this week!
Cheaper != cheap. This does seem to be something many purseholders have trouble with. I doubt Kurtis and Karen are giving out quotes that needlessly undervalue their time. Amusingly in many industries you can run into the problem that too low a quote means you get ruled out. Even when it is the honest cost to do something right. A problem often run into by IT people 😂
*Kurtis
Cost affective alternative to having to pay in digits or limbs for OEM or Factory parts...
@@ZaphodHarkonnen As an IT person, I can only agree. The consultancy fees are sometimes ridiculous, but it's still good value for the customer. We have sometimes been calling in consultants with fees upwards of 2k$ per hour, and it's still incredible value for us compared to having someone with that expertise on staff full time.
Also, weirdly enough, a more expensive IT consultant is automatically considered to be higher skilled than a cheaper consultant. Thankfully I'm in a big enough company we rarely need to call in any external support.
@@teeanahera8949 Kojak don't you mean???
Can't be said enough that Karen could have a career as a video editor/producer. Plenty of other channels DREAM of having such well shot and edited content.
Not to mention her beautiful voice!
i am a retired person in the USA. I missed you folks. Glad you both had a great time taking a break.
I am a retired electronic and computer engineer from Perth Australia. Although your work has little to do with mine I find your precision and quality of your work excellent for some one as young as you. Diligence is the word. Well done to both of you. Your wife's camera work rivals the BBC. Keep it up, I always look forward to it. Pete
One of the biggest problems in our culture (Canada) is our underestimation of our children
I wanted to be & was capable of working at 14
However I was FORCED to spend 4 more years in school not doing anything productive or useful in my life
Been turning parts for over 10 years now but when I think of all the wasted time I get a bit pissy
Awesome camera work and video keep up the good work God bless from GA stay safe
Same in Australia, gotta find a patient teacher, otherwise older blokes are very selfish and try to put the young guys down.😡
Karen’s camera work is WAY BETTER than the British Bullshiting Corporation, cos she’s none bias and doesn’t try too scare the population with agenda driven BS ✌️🇬🇧
@@Sweetchilliheat18 I know what you mean. I was supposed to do 5 years of high-school (in Australia), but left after 2 years. I had had enough of teachers and their silly rules, teaching at a slow pace so the dimmest kid could keep up, a science teacher who knew nothing about science, and a social studies teacher who was a communist. Best decision I ever made.
By the time my peers had left school and got half way through their apprenticeships, I was already fully trade qualified and in charge of a workshop with 30 people.
School teachers are kin to government ministers - both think they can solve any and all problems by thinking up more and more rules/laws.
Hey Kurtis, great to see you both back - many thanks to both yourself and Karen for all the effort you both go to to get these videos out. No idea why, but watching you work your ass off is a real pleasure (and really interesting to see you work on all the different projects and how you complete them) - I look forward to the next video every Friday.
hey mate glad you enjoy the videos and thanks for the words of support we both appreciate it. Cheers!
I love hard work. I could sit and watch it all day!
Agree. I'm grateful to both of them for making these videos.
Listening to a master musician, watching a master artist, or, if you can tolerate it, watching a master surgeon operate, is similarly enjoyable and impressive.
True talent is impressive in any profession. They make the difficult look easy.
@@Absaalookemensch I once spent an hour or so watching a bloke dig a trench. And he was a MASTER trench digger. It was honestly a pleasure to watch.
The end result looked like it had been cut out of the ground with a laser. Straight walls, flat bottom, perfect arc across the yard -- bloody beautiful!
@@dfross87 Any master in their craft can be respected.
That's why I look for those who master their profession when needing work.
My wife has cancer and we're blessed that her Oncologist is a master in his specialty. She started immunotherapy treatment and didn't do radiation treatment because proven protocols were just released a few weeks before her diagnosis.
A master continues their professional development their entire career and is never too old to learn better skills.
This is great content. No gimmicky music or effects and makes you feel like you're there. Well done guys! Appreciate it.
Hello Down Under,
Karen do you ever get tired of watching Kurtis work his magic? Well, I don't. !!!!!! This the second time I've watched this particular vid. I love them all.
I've commented before about the rigidity of your equipment and how easy you make it look to cut threads. Beautiful work.
I find it amazing that kurtus can make a brand new rod that is much tougher as apposed to just getting it rechomed.
Better than new!
Not to be a spelling nazi. But, it's KURTIS as in Mr. Allen
its actually much cheaper than rechroming, at least where we do it...
@@quadrannilatorwhat makes rechroming so expensive?
@@hannahranga Where I work, our chrome plater uses electrolytic plating. The only other alternative being thermal spraying.
If the cylinder rod is just plain carbon manganese steel, you can de-chrome it using chemicals. But, many a times cylinder rods are made using steel with alloying elements, most typically Nickel and Chromium which enable them to be hardened via heat treatment, such as this induction hardened rod which Kurtis used in the video. So electrochemical dechroming is not an option because it will also leech away the Chromium inherent in the base metal.
Such rods are also badly damaged with deep dents and scoring, in which case the chrome deposition also has to very deep. Typically cylinder rods are chromed and then ground in multiple passes with radial chrome thickness typically not exceeding 75microns.
Straightness, Runout, Size and Surface Finish of the rod are very important for good functioning and life of a hydraulic cylinder. You don't even know how bent an old rod might be - so rechroming it may need high thickness and make it difficult to achieve geometrical accuracy. The old material will have internal stresses and micro cracks which may have already weakened it.
Electrolytic plating is a very hazardous process involving toxic chemicals and gases and hence is done in only special facilities under licences and big environmental regulations. So this makes the overall plating and regrinding process an expensive affair.
Its just much easier to buy a plated rod or get it plated and ground from new base metal. The cost of plating, which also consumes a lot of electricity, as its area gets larger and maintaining all its accuracies in long and big rods often far exceeds what you pay for a new bar of raw material. And you also have full control over the alloy composition, heat treatment and chrome plating process if you make a new rod.
I hope my experience was a used reply for you! 😀
And finally we got our entertainment for today 😂😂
This video is not boring, we'll it's feature boring but entertaining all the same. Love they qualiry of the work,.
Kurtis, you guys don't ever do work that's cheap. You offer exceptional quality engineering goods and solutions that are more cost effective for your clients. A very niche enterprise conducted and orchestrated by very respected people. Hats off to you guys once again !!
A friend at a wire rope sling manufacturer company needed your services years ago. Too many years. It was a 300ton x 6inch stroke machine press and it pissed all over everything pinching large collets/collars the barrel was huge. If it didn't have an electric pump? It wouldn't have worked at all. Hand pumping would have bled completely off. God how I love your work! Phenomenal!
Kookaburra sits on the old chain link fence....wait, I feel a song coming on. Great stuff, thanks for posting.
No CEE and no Matty's Workshop last week. I thought the world was ending so I'm glad to see you back.
thanks for your support, send lots of positive vibes Matty's way please!
Yeah, sure hope Matty gets well sooner than later. His 'Rust' video says it all. Quick recovery for sure!
@@CuttingEdgeEngineering Absolutely. I sure hope everything ends up working out for the best and a speedy recovery.
glad you're back from the mini vacay - missed you all and specially homeless - and george.
Dear Kurtis, Karen, and Homie I happened on to your channel a couple of months ago and have binge-watched nearly every video. Being an old man from rust belt Ohio USA I've always had a soft spot for tool and die folks. Your skills are only surpassed by your wonderful wife and dog! Thank you keep up the great work!!
Watching Kurtis double check his settings for the threading .. reminds me of doing the same thing with fuel transportation when loading/unloading. Cuts down on the mistakes.
I got a laugh out of the "checking my scratch pass" on the threading. 😂
Karen, listening to the out-takes, I reckon you're ready to start your own machining jobs. Great viewing as usual. 👌
I do so enjoy how you interact with your lady, the dog (Homie) and the magpies.
Kurtis you need to do a video explaining step by step how you progressed from a service truck employee working in the field to getting your start in renting a building and getting your first lathe and building a business that thrives today for you and Karen. TH-cam, obviously, has helped you immensely, but your 6 days a week 10 hour days customer attention has sure helped. If you were in America we’d call it living the American dream. And that’s high praise, my friend!
Well, it’s 1AM here in Idaho, USA. I was planning on going to bed “early” tonight, but now I’m not so optimistic.
Howdy Right here near Priest River ,Idaho, USA and had the same problem Kurt, Karen and the critters kept me up and of course always love the turning lathe.I remember my first thread job, how time flys.
love the butcher birds moving in.
As a sidetrack...
MATTY's WORKSHOP is on PAUSE till he recovers from a medical issue. He may pivot, and create videos of his recovery IF there's an interest.
Nothing but the BEST for our friends from down under.
Bronx Love guyz 😎
Blows my mind every time I see threads done on the lathe. Intellectually I understand it is just gears and cogs moving all together to make a repeatable pattern, but there is something magically about this process and how it works.
The outtakes show the critical process of checking the pitch with a scratch pass before proceeding. 😉
Try setting everything up again next day when you've run out of time in HS shop class! He's also got that foot brake, woulda loved that!
Midnight on the west coast but what’s another 30min 🤝
The right choice was made here 😂👍
Good to have youse back..I didn't know what to do with myself last Friday 😁
The close up of the centerline of the facing cut on the threaded end was fantastic. You make this work look so easy dude. Love to see an animal friendly shop.
A work of art by a craftsman. I’m 99% sure when it got to the job site a bunch of dipstick mechanics were dragging the jack around with a bobcat. Keeps Kurt and Karen in business though.
Compared to some of your recent larger projects, this one was really easy and quick! Hope you had a good time off last week.
Man that ceramic on induction has my tinnitus, going thru the roof. I couldn't do it all day nice work man.
and I reduced that audio by about half 😅👍
I am truly pleased to hear many of the followers of CEE recognize the level of precision , level of detail , professionalism and the master craftsmanship of both of you . I am old now , worked hard and saw many blue collar men . Few focused on reaching there goals . Thank you Karen and Kurtis . HBN ,is a very cool dude .
Good post, getting rid of the induction hardened layer used to sound like nails on the blackboard. Nice simple job, shame that the old one got misused, but gives you business. We made a gearbox for Heathrow airport which jacked up the 747''s nose wheels so they could change the tyres. That was misused, and eventually seized up. I had to repair it within 24 hours due to scheduling, which we did. All for the sake of some oil and grease. Loved the birds, thanks Kurtis and Karen, be safe and well 👍
What is this "oil and grease" you speak of 🙄?
I feel that you using the term heavy duty is superfluous at this point as I can't recall you ever doing things on the small scale, I love the content :)
I think Kurtis would go cross-eyed at trying to do some MEMS work 😅
@@LadyAnuB what's MEMS?
Microscopic stuff?
@@Sebastian-ed5kt Microelectromechanical systems
you know what’s cool about your videos? I don’t even have to watch it to hit the thumbs up. I already know it’s gonna be good. Lol 😊
thanks heaps for that support we appreciate it!
CEE again yourself and Karen such great video I sit here on the knife edge watching I totally love all the process of the job in hand absolutely amazing best regards from Scotland 🏴🏴🏴❤️❤️❤️
Good old imperial thread angle on that. 55 degrees was what was standardised across Whitworth and BSF threads early in the 20th century.
I had to call my broadband supplier last week as there was no CEE video and I thought it was broken. Good to see you back. It was worth waiting for. Thanks for another quality instructional video.
I amlost died last friday without movie.... fortunately you are back :)
Missed you last week. I liked the triple check of the lathe setup when threading. Check the chart, adjust the machine, double check the machine, recheck the chart. Excellent procedure and discipline. Saves a wasted and very expensive blank. Love the channel.
Had to watch it twice to get my fix from not having a video last week😘😘🤣🤣
Good to see y'all again. I hope your rest and reorganization was most beneficial.
Yes it sure was! Was a bit weird with no video last week but we both had plenty to do so it was a good change
Friggin' better, harder, thicker induction hardened chrome. Better and less expensive. You're a black fire opal of a gem out there.
it wont be long and your going to have one of those birds sitting on your shoulder while your running the lathe....how cool is that gonna be,well done and again,thanks for sharing!
I haven't slept in over a week, no machining, no squeaky toys, no George and friends, missed the giggles, a lack of 'Fuck off train', or 'Is my hat straight?'. It's so good to be back to normal proceedings. Thanks guys, have a great weekend.

The next time I ever have anything machined I'm going to just STFU and not complain about the cost. You show so many sides of what it takes to do your jobs that I'm sure a lot of people didn't know about. Just thinking about your overhead and all the work involved is amazing. Thank you both for all of these awesome and informative videos. Hats off to you both and your dog and birds. You all make these videos fun to watch.
Nice job. Love those birds.
... Welcome back, Kurtis, Karen and officer !!!
I love the birds in the shop! And what a treat see such a vast piece of steel being handled so well! Thanks!
That Butcher Bird is nearly too fat to fly . He is living on Easy St.😊
If they ever left droppings on my machine & tools, we’d come to a parting of the ways. I’d declare war on the birds.
Nice to see you back! Can't wait to see Curtis work his magic.
I hope you two enjoyed your break! This part is fairly simple in comparison, but that doesn't mean it's easy and I think the great majority of people here get that.
P.S. treat those magpies like family. Scold them when they are bad and reward them when good. They are smarter than you think, and they never forget 😊👍
George isn't a magpie. Kurtis says he is a butcher bird. Looks like a magpie, but about half the size. We also have pee wees. Same colouration as well, just a little smaller again.
I just watched one of your videos from three years ago when Homeless would only peek out from behind the lathe. You've sure brought him a long way to such a happy dog.
we've all come a long way, Kurtis talking still needs some work 🥴😂
@@CuttingEdgeEngineering Yeah, I always watch the outtakes.
@@CuttingEdgeEngineering Kurtis will talk pretty one day 🤣
@@LadyAnuB That'll be the day the audio packs up, and Karen won't realise until she goes to edit 😇.
@@dfross87 😂
Welcome back! Keep the quality content coming. Love from UK 🇬🇧
Cheers mate we will do!
Thanks for all the great work you do. I have a deep appreciation for those whose pride in their craftsmanship allows them to accept only the very best they can do. I also had a panic attack last Friday. Hope you enjoyed your week off from video editing. By the way, that 3-part series on the D8 dozer blade rebuild was simply amazing from both of you. Oh, love the birds and of course Homeless. Rock on. Oh, by the way, you are never "cheaper". You are "less expensive." I don't believe "cheap" can be applied to anything you do.
Hey mate! Wow cheers for the super thanks and your generous words! We appreciate it mate! 😎👌
I've seen a lot of similar videos now...but no one who handles their material and machines so carefully! You can learn a lot of things...but it's in your blood or it's not! Love your videos!
Greetings from the States! Hope you guys enjoyed your break last week. Glad to have you back. Oh, not to mention another top quality project out the door. See ya next week! Cheers!
I also love how you save big old machines I've never seen. 🖒
6" x 550mm. I love it. You're bisystem. I'm in America and I wish we would convert to metric faster. Eventually we will, but it's taking too darn long. Having tools in both systems is a pain. Needing things like 11/64 rather than 4mm is just silly.
I love your work. If I were a kid, I would have wanted to apprentice with you to become a machinist.
Aren’t you afraid that one of those small snake’s will get him. He’s a beautiful little guy. Love you guys from Jackson Michigan USA
I'm here, pint in my hand. Hope you guys are doing great!! Hey Karen, I saw the split screen during the threading. Very nice! You need a raise!
Thanks mate we are, hope you are too!!
The humor of checking you thread pitch AFTER the scratch pass probably flew over the heads of most folks. Good one! Cheers! You folks are very good at what you do. Keep on keeping on.
It's not humor. It's confidence!
That joke probably flew over your head too. I KNOW he knows what he was doing, but a scratch pass is done to verify if your machine thread cutting setting is correct after an actual scratch pass as a sanity check before you go to town and cut the threads to full depth.
It's 05:00 here on the East Coast of the States, and the first thing I see this morning is CEE-A.
Don't go anywhere; I'm headed to the kitchen for my first cuppa joe. Be right back. What a great way to start the day.
Okay, I'm back; carry on.
Excellent video, as always, with loads of giggles at the end. Nice job on the threads, it's always good to see someone doing it the traditional way. As for the Butcher birds, most Aussie birds will take a very long time before they will take food from an outstretched hand, I found years ago with Magpies that they will happily take food from your finger and thumb but not the open hand. We had generations of them in our back yard and I used to feed them dried cat food pellets, they loved them and would come into the garage while I was working and stand behind me - I'd sense someone was there and turn around to find a couple looking up at me. A few cat pellets and they were as happy as Larry (whoever he is, or was).🌞
Good to have you back.
Those pins in the top can act as a consumable and also will spin when needed in order to lessen that rotational scoring they had. Sometimes they will be knurled to avoid slippage also. Five bucks says the customer has lost the one that is supposed to be there.
I'm surprised that you didn't turn a new cap for the piston.
Thanks for the vid - hope you enjoyed the break.
That piston came off way too easy 😅
All the best,
Paul (sending good vibes to Matty).

Bonus points Kurtis for the wildlife documentary. Cheers to you and Karen and Homeless and George. Staff numbers getting larger and larger eh? Nice job too.
That was an excellent cut from when he dropped the rod to the forklift coming into the scene. Nice!
You learn something everyday. I have never used the higher functions on a dro, just the minimal.
Wonderful, a new video! Needed my fix of a new CEE video 😂. Thank yall for the quality content as usual, Cheers from California!
Love it when the video starts with Homey squeaky toys!!!
Another fantastic video! Thanks for posting!
Hi guys, hope you had a good time off.
A nice fix this will surely be.
Cheers!
👍💪✌
The MAN. the Mythe the BIRDS 😉 love it !!
8:29 Look at that cute little pilot drill 😂
I like the way you take care of your shop tools and equipment. a clean place to work makes a job easier
Using the packaging the stock came in to protect the finished product is genius.
Everything is big at CEE Au, even the scratch pass! Another great video. Thanks.
I love it when you two lovingly snark at each other. :)
I just love hard work. I can sit down and watch it for hours.
Good to see you guys enjoyed your break from filming, everyone needs a break to stay fresh.
I see that ‘Inheritance Machining’ is getting behind the banana as a legitimate measurement, I get strange looks and also identify some closet CEE fans when I use it. Keep it up guys, great channel.
Inheritance is American. They are a funny lot who won't update and use the metric system, because it is un-American (or Not Invented Here).
Apart from that he's pretty good though. I've learnt a lot from Inheritance, Artisan Makes, and Kurtis. Learnt a lot more from Kurtis though.
Six bananas in diameter the rod. Not possible to be all metric- wheel diameter inches, flight height from ground feet & nautical mile at sea in knots. Learn both, conversion apps are essential.
Hi Guys, a bit late to the party but I have watched nearly all your vids. Homeless isn't spoilt, he is a pampered pet. Just waiting to see more of the new yard crane. keep up the great work. Cheers
Edmo are just down the road on the Gold Coast. Just one of those little old school companies that makes good stuff. Doug Storey was the original proprietor, his brother Mal is well known in the Land Rover community around the world for his diff locks, axle shafts portals among other things under the MaxiDrive brand.
I think Edmo also made or make mining tyre change equipment.
Finally George are from your hand, nice progress.
Great work guys, keep it up 👍
Thank you! Will do!
Becoming my new Friday arvo ritual of having a beer and watching something get built.
22:53 DAMN! He just plunges right in! Full Bull! I'm usually very skittish and overly cautious whenever I start. I have baby start it by just making a scratch pass, then check it with thread gauge to make sure it is correct. Our boss drills that in to us to double check so we don't end up scrapping a pricey rod. Which I have done more than once by accident.
Well, Kurtis, you screwed that up beautifully - again.
I deeply enjoy watching your videos! While I don’t machine large parts, I do make pens on a lathe. Kurtis your ability to tell us what you’re doing is exceptional. And Karen just keeps getting better and better with the editing and filming. You make a fantastic team. Glad you took some time off, but also glad to have you back as Friday just isn’t quite Friday without a video from y’all!
Couldn't have asked for a better video to watch before bed
Your "scratch pass" made me spit my coffee halfway across the room. Good video, I always enjoyed turning that 65 rockwell stuff.
Cool how the birds come right in and hang out . Always wanted to visit Australia
Even your more "simpler" jobs are a joy to watch because you take the time to explain where the piece is used and how it got to the condition it is in now. Excellent work with the videography and editing Karen. Thanks you two, three. I'm still amazed at the knowledge you have Kurtis in the field you work, at such a young age.
Hey mate, @2:12 If they are putting these jacks under extreme "tension", then you will probably be seeing more of them come through your doors 😄😉
Love all these videos. Takes me back to my metal work lessons at school. And I’ve got my new hat delivered here in 🇬🇧 UK.
It's always a good Friday watching Kurtis and Karen. Question Kurtis what is the logic behind using a spiral tap instead of a normal tap?
Hey mate good question, Spiral taps for the metal chips/swarf out of the hole and not push it into the hole 😏
@@CuttingEdgeEngineering thanks
Welcome back to you both, And of Corse the safety officer. Now not lets forget the Murray Magpies as well :) Top Job Mate as always. Nothing Cheap about the work You Knock out. I like this induction Hard Gear pretty Dam tuff stuff. Great to machine once you Get through it.
That was a nice little warm up job. Welcome back you two.
😂😂 ‘Check my thread pitch after my scratch pass’… damn I had to pick myself up off the floor as I was laughing so hard.. 😂😂😂
