Repair DAMAGED Cardboard Compacting Auger drive shaft | Machining & Welding
ฝัง
- เผยแพร่เมื่อ 17 มิ.ย. 2021
- In this video we are repairing a damaged auger drive shaft off a cardboard compacting machine. The shaft on the auger drive has been badly damaged from the bearing locking up. To repair this we need to set that part up in our lathe and machine out the damaged shaft material to prep for welding. We then set up the shaft on our rotator and weld with ER70S-6 mild steel MIG wire. The auger drive shaft is then back in the lathe to finish machining the weld down to spec.
In this video we are using:
- TM-26120G Centre Lathe
- WIA 500i Weldmatic welder

Another great repair!! makes sense to weld up instead of replacing the shaft section if machine is just going to be used for a few months, I'm sure it will last along time anyway. When is the Shaper going to be moved into the shop? Looking forward to that one. I've got a 26" Shaper which I bought of a Engineering shop in Rockhampton QLD that closed down around 3yrs back. It come with some heavy duty tooling for internal keyways etc which I will never use. I could send them down to you if you wanted them as I would never use them doing Motorcycle repair. I live up at Gympie which isn't to far away.
Friday wouldn't be the same without you guy's, thanks for week
Já sigo vocês,achei boa a intenção de vcs não aceitarem contribuições para o canal.penso que trabalhão com o coração!
A work of Art !!!
The stuff that you do is grate
your "no Warranty repair" is better than most "Warrantied" repairs I have ever scene
🤣 thanks mate!
Well it's Kurtis, of course it's gonna be amazing work haha
Glad someone seen the scene
Facts.
Spot on. 👍
"Nothing is more Permanent then a Temporary solution that Works"
I'm betting this shaft will be in use for a long time. Fantastic job
I wonder if it's still there...
The machine was pulled out in July this year and was still running with no issues after the repair had been done.
@@bigeggsr2336cool, thanks mate!
How many times have you done a temporary fix, and then gone back there 6 months later and alter the rest of parts whatever they happen to be to be the same as your temporary repair😅
Your camera work and editing is exceptional Karen! I love the hand held shots where you slowly walk into the scene, that really gives the viewer a strong sense of actually being there.
Sometimes I feel like I should be handing Kurtis a caliper or patting Homeless.
Thanks very much! Really great to know it's being enjoyed 😄
It’s so good to see a young guy with his own shop ... doing REAL WORK .... with REAL VALUES! Even though it’s a No Warranty repair you still went above and beyond.
bang on ... you hit that nail on the head .... Kurtis AND Karen give me hope for the future of mankind ... please have children K&K, keep that DNA line going.
@@spangy8405 Whereas anonymous cowards like you should never be allowed into the gene pool.
Not even at the shallow end.
"Machine is going to be replaced in a few months... " , I am * almost * willing to bet dollars (US) to donuts that you'll get this exact same auger drive shaft back in a few years when the bearings fail again. :D
😂 seems to be what most viewers are thinking. Thanks for watching
Have you priced donuts lately?
That or it'll be sold off as refurbished
People that say this shit are 99% just trying to save face and not have to admit "we're broke AF and are barely staying afloat, I/we can't afford the extra $xxx for a proper repair" and are going to be using that machine for years to come. They'll probably even take it to a *different* machine shop next time, again, to save face and not be recognized lol
Edit: I speak from experience. I've had to have stuff repaired and not been able to get a _proper_ job done, just " _good enough_ " to get me by a while, because I was soo damn poor lol
I like donuts!!
Oh by the way Karen you do great camera work I'm glad you talked him into filming these
Thank you!
Fantastic work with the camera and editing!! I suppose you do the editing as well?
I love the way she follows the machinery like the wire feeding through the rollers, takes me back to childhood learning exactly how it all functions.
@@whatyoudo9773 👍
not to mention the superb music selections ... Karen is a natural at creating an award winning video doc. This lady is as talented as Kurtis ... what an awesome couple.
привет из России! смотрю вас и радуюсь, муж и жена вместе делают одну работу. Мир вашему Дому!
I look forward to these weekly videos more than any other channel on TH-cam. I also like that you guys aren’t flooding the channel with videos everyday and instead just producing quality content.
Jesus that bearing must have been howling when you see how much it gouged out.
I bet the operator had to wear earplugs to run that machine before they decided to fix it?
@@hdezn26 Prolly all the time anyway!
From my time in the bearing business that was the first thing I thought of! Just never understood how customers would run a machine to total failure instead of having it fixed sooner (and cheaper)...
"I came in today and it was howling. It must have been nightshift."
I think this was way past the howling phase...
When I see a new CEE video come, I stop and make a cup of coffee and watch from beginning to end, in full screen! No skipping ahead!
Thank you mate! That's a heck of a compliment in the world of TH-cam
@@CuttingEdgeEngineering I also watch non stop. It is 3:20 AM here and way past my bed time but don't dare stop watching until the end.
@@CuttingEdgeEngineering same here watch all new episodes right to the end.
Skipping ahead on a CEE video? Do people really do such things? Is that even allowed?
What a strange concept!
These videos are the one time I know it will end well.
Until I watched this channel I always thought welding was for joining metal together, I had no idea you could add material to where it was lost! Now I watch your videos and try to guess what you're going to do to fix whatever was brought to you. Thank you for sharing your work!
Hey Glenn thanks for taking time to watch mate glad you're gaining some insight from the vids. Cheers
@Glenn Tillema
I do the same thing! I feel like those aquarium fish in Finding Nemo while they watch the dentist 🤣
Wow! That''s really nice to hear something like that! I truly envy you and the more than overwehlming moment you had when you figured it out! Thanks for sharing this man, really! You help me keep some faith in humans after all! Welding is great and so is machining! Enjoy yourself and every new discoveries you make!
@@obviousness8113 Yup! th-cam.com/video/eJvhoYFS0Bs/w-d-xo.html
We both know that shaft bearing has never been changed. What you did was a very nice job and if taken care of that repair will last.
Kurtis your wife has the sweetest voice and laugh so sweet.
Quite a “looker” too! 😉
cringe
Maybe keep stuff like that to yourself….l dunno, that’s just me.
@@deplorablelibertarian 👍
You two are actually adorable. I'm pretty sure most couples would not be able to work together the way you do. Power to you both.
At the start your safety officer is clearly very concerned that this job is too far gone to be repairable. Then right at the end the look of wonder and respect on his face is a picture. His sigh of relief is perfect.
😂 he's very committed to his job!
I am either missing a joke or I'm living in another universe cause I'm not seeing a safety officer lol
@@vincenttrigg4521 It's the dog. He's been known as the safety officer for some time now.
@@vincenttrigg4521 Newby? Must be.
@@jonka1 that's what I was thinking a while after I posted my comment but I could have been wrong so I thought it would be better off waiting on the answer. Thank you :)
I would give that kind of skill and workmanship a lifetime warranty. Excellent.
I absolutely love your content. Karen is the best videographer on TH-cam, she seems to get into the details for Kurtis' masterful work and shows so much ofteh behind the scenes detail and all of the steps. It is fascinating. Homeless is such a joyful pup, always brightens my day to see him healthy and happy you are great examples of how humans need to be. I hope that "Yeah Buddy" was a shout out to Ronnie Coleman!
Customer states, I am going to switch the machine out soon, so don't do a full rebuild, 12 months later, following Kurtis's repair, why would I swap it out it's working fine.😂🤣😂
With a nice rebuild like that , they probally would keep the machine many more years.
I've heard it before and it's more like 5 years later! These augers can really pack cardboard ! 2 to 1 over a standard compactor. They blow apart a normal rolloff box. That's what I work on,
Yea and 5 years later he wants a new one because your repair failed.
@@billy19461 And he'll want CEE to pay for it.
I bet that is exactly what is going to happen.
When a "no warranty" job comes out good as new, you are so humble Kurtis!
It appears that you do better “quickie” repairs than a lot of the permanent repairs we see.
I’ve never been this close to my lathe work and not have any hot ones down my shirt, in my ear or stuck to my nose. Enjoyed everything about this. Nice shop, tools, abilities, work ethic, videography, editing, sense of humor, but most of all the outtakes. Until I saw them, I thought this was the smoothest operation on the planet and now that I think of it-it is! Awesome work, both of you!
Homeless always makes me smile. I lost both my little Terroirs in the last 6 months to Coyotes . I sure do miss both of them. Homeless is such a beautiful dog.
I'm sorry for your loss and wish you well
shit mate sorry to hear that! Glad our big boof head can bring a smile
Thanks to all three of you, Homeless for looking viciously cute, Karen for her excellent camera work and, of course Kurtis, for his frustrating expertise, including all the swear words. Real work, real life, real good. Thanks
Great comment mate you captured exactly what we wanted the channel to be about. Cheers! 😎👍
Homeless? Is that the dog's name?
Just I know Karen is Kurtis's partner. Sometimes I just don't pick up on things unfortunately lol
@@vincenttrigg4521 Yes, Homeless is the name of the Safety Compliance Arfacer...
I'm not from an engineering background, so these vid's are fascinating. Curtis is cool, Homeless is class and the camera operator/director/editor does a great, if not anonymous job. Bravo! 👏
What I really like about all your vids is that, not only doing such fine work, but that you have a bit of fun along the way. Throw in shots of Homeless's antics along with the outtakes, and voila, fascinating and entertaining all in one.
'' I don't want to spend any money on it'' says every Owner ever.
🤣☝️ accurate
Sounds about right. One of my tasks today at work was repairing a cylinder base eye, without doing a reseal of the cylinder.
Weld up with the spear extended to avoid melting the piston seal. Then into the mill for a bore. Just another day at the office.
Best part of Friday morning is Cutting Edge and a fresh ground cup of coffee
Awesome mate enjoy and have a good day 😎👍
Just to be clear, the _only_ reason I watch these is to see Homeless. What a wonderful dog. He has such a great smile. I love the way he walks, happiness in motion. Homey makes the best dog noises I have ever heard. Lovely snorts, grunts, and gurgles. (The truth is, watching genius in action, Kurtis doing his work, is the highest joy. Homeless is simply the icing on the cake.)
That whistle says more than words ever could.
sittin' back watching "Rocky Mountain Race Week" vids, CEE pops up, Pause, Switch, Luvin it, CEE, showin' us all how, the true Aussie Way,
Always something different in the shop, Kurtis (Head Machinist), Giggler (Karen, all rounder), Homeless (Safety Officer)
Hey mate! Thanks for taking the time to watch the video seriously appreciate that support. 😎👍
Hey Kurtis, I've been waiting once again for your video. I look forward to them every week.
Hey mate! Thanks for waiting we've got some bonus vids in the works to make the weeks go faster coming up 😎👊💥
@@CuttingEdgeEngineering More late nights for me here on Vancouver island, Canada as I can't wait till morning but always worth it.
When customers comment “don’t spend too much” they always pay. Awesome work. Thank you for sharing.
Master class work. I’ve been binge watching the channel ever since I discovered it. Your work with a lathe is just simply impressive. I’m a millwright in the states (precision industrial mechanic) and by god this is the best channel I’ve seen in a long time that truly puts great effort into a quality repair.
Got my CEE Australia cap and coffee mug recently Guys!!, thanks for that 👌🇦🇺,………glad to support You in some small way, and You Guys should be proud of everything You have accomplished with CEE,……A Proud Australian business!! 👍👌💪🇦🇺🇦🇺……go well and take care ☺️👍
Hey mate thanks for the support we seriously appreciate it and glad the merch arrived for you. Enjoy the vid Cheers 😎👍🇦🇺
Impressed with the steady hand accomplishing the welding on the rotator, Kurtis. Karen, great videography, as we are all accustomed to👍
Who's a good boy Homeless🧸
Should be in horizontal and not vertical position while welding.
If God could put the world on a welding table, Kurtis could make it right again 😉 Thank you for the videos!😁👍
Congratulations! You stepped closer to your razor! Looking good.
Morning from sunny Glasgow Scotland and strangely it is sunny.
Have a great Friday over there mate
It just doesn’t get any better than this does it boys? A Cutting Edge Engineering video to end the week! 👍
There is, however, one BIG problem with CEE videos. We only get one per week!!
@@Watchyn_Yarwood Agreed!
It can be a stress for a couple to work so closely together, but you two do a great job. As skilled as Kurtis's on camera machine work is, Karen's behind the scenes camera work, editing and scene composition is equally impressive, brava! I do worry about the dog being around so much chips! The metal ones, the other kind he can obviously handle...
It brings back great memories of cranking handles, watching chips roll off the cutting tool. Manual machines are so much more satisfying to operate than just pushing buttons and looking through a shield because you can feel the machine working with your hands.
Manual repair machining rules for repair machining since it's faster to make the cuts then code to make the same, generally few, cuts with a CNC.
I retired out of machine work after installing several CNC machines, doing the moving, electrical and electronic connections and just enough "watching time" to know they were properly installed. I had no desire to continue on without the manual machines.
“Coming soon, Kurtis is getting a quick change tool post” I hope that’s not a joke, I’d be pretty excited to see which one you’d pick
It's not a joke 😏
Not gonna happen .
@@CuttingEdgeEngineeringWTF????? Say what now?????
Karen is Kurtis feeling all right?
@@CuttingEdgeEngineering you might get one but the big question is well you use the quick change post ,, or will it become a costly paper weight ,,,
@@CuttingEdgeEngineering But the real question is what kind: dovetail? Multifix?
Hi Kurtis. I love watching your videos, As I like engineering. I would like to say I think your one of the best engineer I have seen on youtube. Because you explain everything you are doing, or the process you are going to do with anything that comes through your door.Just brilliant.
Hey mate thanks for watching and this comment is awesome we appreciate it!
Very nice feeling in the intro with Homey and the acoustic guitar and machinery set up.
Good day. I have always found that most folks that can weld well are not comfortable in the machine shop and vice/versa. Those that can do both well like you and I are rare beasts for sure. It's great to sit here through the process and the outtakes at the end always break me up. Thanks a bunch and have beauty days to come eh.
Hey Dean hope you're having a good week mate. Thanks for always watching and commenting! Cheers, Kurtis
@@CuttingEdgeEngineering When I retired I lost access to he equipment but not the memories of the one-off repairs I would get. I tried a factory type job and by the end of the first week I was out of there like I was shot out the barrel of a 12 ga, LOL. In my work at the logging shop I never knew from day to day was coming at me. I never really knew what a great place it was. Oh well I have you to help fill that void for me. Great videos mate ! ! !
Found this channel about a week ago, then thought to watch a video I have not seen before. And lo and behold this one pops up just as I finished, must be my lucky day. :-) Great channel, excellent skills, wonderful editing and the safety inspector is the cream on the cake.
Welcome to the channel mate thanks for watching!
I highly recommend watching more of the videos! If you liked this one then you'll love the others as well!!
You're in for a treat mate.
@@vincenttrigg4521 You're right. The last time I found a channel I really enjoyed I binge watched every episode which took over a week, and now I have to wait for the next episode and it drives me crazy waiting. Have learned my lesson this time, to take it easy, and watch one or two when it takes my fancy. :-)
@@andrewsmith6406 More than a treat mate, I get a lot of value from this channel. :-)
No arrows pointing to the damage this time 🤣
Wish they did it would have definitely helped 😂
@@CuttingEdgeEngineering 😂
I am reminded of bill and ted , engineering super hero , we are not worthy , we are not worthy. Hell what a great engineering experience every time.
I see Safety Officer / Quality Control chief is looking to give the Paw of approval !
Always glad to see the STAR of the show "The Pup" is happy. You the Wife and the Pup are always a good show. Thank you for another great Video. Stay safe God bless.
Hey mate thanks for taking time to watch and comment
Always look forward to your videos! Homeless is so adorable
He was being a big sook, cold winter day kept him inside haha
Curtis, once again you have done what my dad always said.
You made a silk purse out of a sow's ear.
Bang up job! Right proper finish too. Always a joy to watch someone else work.......and wish I was still doing it.
Cheers!

Hi, Curtis. I have a title for this video: "Beauty From Beast". Beautiful job. Thanks for sharing! Stay Healthy!
Amazing that you don’t have any “air” bubbles in that weld 👍
I think this is the first video I've ever seen you indicate when you mounted the part. I thought you might have some special Aussie magic or a calibrated eye. :D love the vids!
Hey mate hahaa we've shown a few snippets in older videos just prefer not too, boring AF and plenty of other channels make up for it 🤣👍
I enjoy watching you preform your magic on your projects.
First thanks for making the video and showing it to me.
Fortunately this was only a short, not too thick shaft.
I once did a similar repair on a very large thick axle.
Same problem, bearing stuck.
I also welded this axle.
I only did that welding on a lathe.
Reason: I didn't want to stop welding and attached the welding torch to the support.
Gives a much more regular weld.
The reason the bearing got stuck was because the fit of the outer ring was too tight.
I made sure that the outer ring had a loose fit and put pressure on the outer ring with a cup spring.
The machine has never given a problem again.
If you had used the micrometer as aa G clamp , you would have been spot-on 😆😆😆😆😆😆
Yep, precision G clamps.
Always keeping me entertained on the night shift here in the states. Keep up the great content! Also that pooch NEEDS a girlfriend.
Awesome glad you can watch and enjoy. Haha he's had a girlfriend and ended up making 8 pups 😂👍😏
@@CuttingEdgeEngineering now that’s funny. Probably denying the whole incident.
@@CuttingEdgeEngineering That's what you get with one like a ripper shank.

Why is it so intensely satisfying to watch Swarf being made for so long?
Brilliant job on the cling wrap! The repair was pretty cool too.. Enjoy that beer Carl, you earned it!
Dang, they tore that up real good...
Fantabulous video as usual. Tough work being a safety inspector oh and love the little dig about the cling wrap at the end. Well played Karen...
🤣 cling wrap is the devil! Thanks for watching mate glad you enjoyed it
Your No Warranty is better than any shops I've encountered in the southern U.S. , I'm sure the owner was thrilled with your repair , like I always say , there are machinist / fabricators , and there's Kurtis at Cutting Edge , Your the Man !!!!!!!!!!!!
Hey Barry thank you mate appreciate it
Nice job Kurt, a big thank you to your wife and a pat for Homey
Cheers Mark thanks for watching it!
First question to mind on the start of the video was why not spray weld, answered in first minutes, second question that came to mind, where did the measurements/specification come from, answered a few minutes later. Thanks guys, Friday started off well.
Looks like you saved the day, that was bad, I've built up a few bearing surfaces but that was a save for sure. Great job.
Hey mate respect and thanks for watching 😎👊💥
I noticed that Karen videoed the settings on the welder & put it in the foot notes. That’s nice easy to understand. Thank You Ma’am
I must say the most excited I go was in the last 5ish seconds of the video. I can't wait to see it!!!!
Have to say but, that was definitely one of those pure neglected type machines.
I'll take you're "no warranty" work over many other's so called professional work. Just a pure pleasure to watch and see your quality of work. Awesome work as always, great video. Cheers :)
Thanks for watching mate
Another mint job👌
You should have given him at least a concrete warranty as soon as it leaves the concrete it's out of warranty 🤣
Hey mate will have to use that warranty clause next time 😂👍
@@CuttingEdgeEngineering when I get asked to do a sketchy repair, my favorite warranty is the 50/50. Fifty feet or 50 seconds, whichever comes first. Great video
@@CuttingEdgeEngineering Keith Fenner's SHOP LABOR RATE - IT'S NOT THE COST OF THE REPAIR. IT' THE COST OF THE DAMAGE YOU CAUSED. This is a sign in his shop.
Kurt you have save your customer a lot of money doing this repair shame on them for not doing the proper maintenance the repair is better than getting a new part and no warranty as it should be the damage was so severe. But you came to the rescue. Love the video, I can't wait for the video every Friday here in the states. Thanks take care.
Hey mate thanks for watching and supporting the channel we really appreciate it. Cheers!
Beautiful choices in background music, comforting, peaceful, mellow … ahhhh
Thank you for the vid mate! really appreciate the quality of your work and the camera work of the lady.
Thanks for watching glad you enjoyed it 😎👊💥
Great welding /machining. Pro grade filming/editing. Loved it. Regards to Homeless.
Thanks Ian glad the videos and work are being enjoyed 😎👍
I've watched almost all of your vids guys, the early one's showed that you had just started, must say great to watch, I'm retired now and all that's missing from watching is the smells of the shop, the hot oil, burning paint, new paint you know what I'm on about, I'm surprised the the lady can stand the noise tho that very unusual in my experience,
Then along came the music !
I thought oh here we go just like the American vids they all think they're a professionally produced TV program, but ye know what, who ever is doing the editing has hit a perfect balance, just the lightest of touches with the music and it the right balance of music type as well, I congratulate you all I can watch all day, well I have on some occasions, all the best guys, oh by the way Kurtis your a damn good engineer m8.
Thanks for the interesting things you do on this channel. It is nice to see someone that doesn't take the thrill of the noise made by the equipment when repairing or making something and cover it with music. PS. the dog is the best!
Great end to my week every week is getting home from work and watching these. Great video as always mate.
Nice one glad you enjoyed it and have a good weekend mate
Your vids always get posted at midnight my time.. Luckily, it's the one day a week I work graveyard. Always makes my Fridays go by so much faster!
We do it for you 😉😂
At least the day shifters are asleep by then. At least I can watch videos in peace. Till, I see daylight again and think, Oh crap I stayed up waaayy to late again...
They show up about the perfect time for me in West Aus, finish work, couple of pints at the pub with work then home to watch Campbell work his magic.
I follow Demolition Dave. He does blasting magic.
we've watched some of his videos!
The outtakes are hilarious! Almost the best part.
For a 'cheap' repair that was impressive and cleaned up pretty well! Great camera work on this one too. Hope Homie is OK - he did not seem his usual ebullient self.
Hey mate thanks for the great comment! Yeah he was alright just being a sooky it's winter and a bit colder than normal 🤣
Very good job. I do some turning and I can see you managed an excellent finish.
The packing machine running with the busted bearing grinding into the shaft must have been truly painful to witness.
Aww Safty pup is having a lazy day.
Ok now my Friday can begin.
The man with patience.
Another great video! Thank you!
Side note: I'm not a machinist (yet) and I don't even own a lathe (yet :D), but I've previously seen people express the idea that using abrasives on the lathe (24:45) isn't so great for the ways and thought I would echo it in the unlikely case you hadn't considered it.
Also I think you should definitely make petting part of your business model. "Hello Mr client, we've now petted the part so it's ready for you to come pick it up".
When you said making "petting" part of their business model, I thought you were going to say that people could pay to pet their dog XD
Hey mate thanks for watching and sharing your comment! Yeah abrasives can get under the carriage and damage the bed ways. Using antispatter sprays, regular cleaning and maintenance helps to avoid that. Cheers
Не важно в какой из стран мы все живем, главное что бы вот таких людей было по больше и тогда мы уже спокойно летали на Марс.
I started watching because i love how easy you make it look but now i watch because i love the dog. LOL!!
Super impressed that there were no bad spots in all of that weld. Congrats on another successful project. Skip the welding screen and show more of your dog during those long welds. Cheers
Thanks for watching mate
love the dedication of the plant safety officer..
I'm a retired bowling center mechanic. I used to make similar repairs on shafts, using nothing but a stick welder, file, emery cloth, and a drill press. No calipers, no lathe, no angle grinder. Of course, the shafts were mostly 12-25mm (1/2 to 1 inch), not the 130mm monster you fixed.
File off the worn area with a round file, fill the recess with weld material, chuck it in the drill press, and turn it, using the file to knock down the weld material until it was level with the good part of the shaft. Then polish it all with emery cloth.
Normally took me half a day, and saved the owner a hundred bucks or so (he figured he had to pay me anyway, so didn't count my time).
perfect repair cant even tell it was repaired as we have come to expect with your work so much care and attention to detail !!!
and i would bet Dollars to Pesos that the part that was repaired will outlast the machine that it’s installed on, due to the high quality of the machine work that was done
Sad to see how little they were watching the equipment to have it do that much damage. You did a very nice job on that shaft.
I could swear I could hear everyone shaking their heads "NO" when we first saw that chowdered shaft. Amazing recovery on that piece of crap.
Been welding since 1998 and I worked in a machine shop for 8 years. I've done so much build up like this. I've never seen it done in this position. We were always able to turn the shaft into the horizontal position. Pretty cool to watch.
Regardless of what you are fixing, it is always great to watch a master at his craft. I love the videos and the engineering talent you have is second to none. Thanks for sharing. Very entertaining.
Hey mate thanks for watching and commenting. Cheers!
Hello Kurtis, this was really a lot of welding. Well done. Like others I think that you will see it again in your shop after a couple of years.
man I get a big kick out of your commentary about your work .you are an artist at what you do I love watching.
Glad you enjoy it mate
My wife loves the Staffy. I'm here for your ingenuity....
I'm quite sure, that one of these days in 2031 someone will be pondering: "Huh, they must have had the shaft repaired before!"
