Never seen this channel. Never heard of this line of work. Didn’t even realize those joints on the equipment needed this kind of maintenance. Video just popped up in my recommended feed and I’ve been casually following along for about a half hour now.
That level of skill has a value that is almost unimaginable. You guys blow me away with what you do. My brother is a shop superintendent at large construction outfit up here in Washington state, watching him fabricate stuff is like watching a magician to someone like me.
Let’s not be hyperbolic. This skill Is not unimaginable. There are soooooo many things in this industry that makes This look like a Job you’d give the new guy. And
What would be the time cost difference to set the line bore setup up then gouge the tube off and then set the new tube up with the grease connection done right and then weld and then line bore?
I work twelve-hour shifts TiG welding aircraft parts so I feel your pain on those long ass days! That Pie mode welding is pretty slick. I've been dying to attend a Fabtech Convention so I can keep up with all the new tech and processes. well done Sir!!
Absolutely awesome, I’ve been welding on heavy mining machinery for almost 20yrs and weld those bores by hand and never knew a welder existed for that. (I’ve Probably been living under a rock) this is beautiful to watch. Thank you for your artistry.

Been a welder/fabricator for over 30 years and thoroughly enjoy watching the younger generation and following up with modern techniques to "GET 'ER DONE"!!!! Really like that facing fixture you have - sweet!!! Like having a lathe for something you can't stick in one! I hope you showed your customer this video so he can see for himself the excellent workmanship he's paying for.
Nice feature with the back and forth fill up, that bore looked like a railroad tunnel, I expected that you would have to bore it out to the biggest diameter and weld it back to spec, but the vally filling helped a lot! Thx for showing! 👍👍👍
Thank you for the explanations, I'm looking to get into line boring and trying to soak up every bit of knowledge possible. You make a great TH-cam mentor.
Slick repair! Man your making your way up in the rankings of welding on TH-cam! It's crazy how much people watch you just do your job! There's barley anybody out there uploading stuff like this so definately keep uploading!
I don't own or operate any heavy machinery so it is unlikely I will ever need to know this is even possible, but, I can say with certainty, I can appreciate the amount of skill this takes. This is an invaluable skill set.
That's almost the exact line bore I use @ work. It's in a shop so we use the BB5000. It took me a few hours to get to know the machine years ago and it's super cake doing anything nowadays. Nice work, thanks very much for sharing. I do a lot of small articulating dock crane work for the fishing industry. Those guys beat those cranes to death before they say 'Uh...we better fix that.'
We did use someone like you at my job saved us alot of money to repair some errors ,so hope besiness owners will see how very useful you guys are,keep doing what you do sir
That was certainly worn!, quite a difficult operation to maintain lubrication points. Impressive PI or PIE feature and weld interrupt. Great work and video, thanks for sharing. Regards John
Your knowledge of the proper tools, such as the line borer, and skillset in using them properly in field conditions, and obtaining the precision to do such quality work is truly outstanding! You truly have my respect, and I want to express my sincere gratitude to you for making these videos! As a fairly new welder, out of welding school a year, I am learning so much from your expertise….thank you!
I appreciate your excellent discussion and explanations of how and why you are doing what you are doing. The Climax rig is impressive. The only line boring I've done is engine block boring. This is a different caliber! Thanks very much and greetings from Germany.
I started watching your videos a few days ago when one poped up as a suggestion. It was you welding an earth mover which had developed a serious fuel leak deep inside one of the machine's arms. You cut out several large plates just to get to the leak and despite all the flames you successfully welded the many cracks, splits and replacement panels to seal up the tank once and for all. Brilliant job and much skill involved. I was impressed by the shear volume of different situations and problems you dealt with on site and in your workshop. I watched a few videos and subscribed because you do a lot more than set a machine to do your welding for you. I've watched three videos on line boring and this one is by far the most not just interesting but skilful because I had only seen complete revolution welding, but in this one, the borer welded the bottom part first bringing it to a level where full revolution welding was possible. That matchine is bloody marvellous. Your apprentice must be in his element because I would be if I were in his shoes.
There is so much more to this than people realize. The weld build up you don't want to be excessive because of machining time. And its best that finish isn't between layer's so peeling of the weld doesn't happen. Great job!!
I would have thought that you would have to treat the metal somehow if you did something like this. This is fine the way it is, no heat treating or anything like that???
@@mitchweber7868I don’t think you would need to per se. Since its a continuous weld surface on a single parent material. Plus there are bushings on top.
That is the first time I have seen that sort of work from the welder in line boring. That "pie" mode is a really handy function, they rarely wear out evenly!
thats insane. I used to be a commercial landscape foreman and would see you guys come out and work on busted excavators and backhoes etc. I never did get to see what was going on up close though.
This is a really good video that the guys that hate paying for repairs and should see why it cost so much to repair . lots cheaper to replace a bushing and pin then wait till is half way through a arm lol. Great work cheers from Australia.
I have to say you do fantastic work, I have heard of line boring and did not know how special it is. I don't do your sort of welding ,I do mostly regular fab work , not on heavy equipment. On seeing your work I wish I had know of it sooner, great work your are a master welder.
Hey mate, surely that line boring machine is worth every cent that it costs. Helped you turn a mushed up piece of machinery back to near new. Well done.
At your support and skill level to take junk and make look factory when you are done!!! Your videos are so entertaining and educational. Your Equiptment is 1st class and just what you seem to need. Night lighting is above par!!!!! Enjoy
Awesome work man. I’m a heavy mechanic and I really like watching this kind of work done. I try to stay out of the guys way that does this work for us when he is busy.
You are amazing! I would love to apprentice and learn from you! Such professional and clean looking final products. And you have the right tools for the right job! Awesome video, Thank you for posting.
That is a very clever line welder, what with filling the "out of round" bottom of the hole and also being able to jump over the grease holes. The machine designers certainly thought about it. We are definitely an intelligent species. Great video.
I like this style of boring system that you have. It looks light weight and very useful, un like the system that a person is using in Australia.Good job and video!
That's a really nice feature, perfect for that situation. Idk there's something kinda hypnotic about watching that torch going back and forth. The interrupt button is another handy feature, it's a pretty sweet setup. Climax.
This was one of the coolest processes I've ever seen. I wish you had shown a bit more of how you set up your line bore in regards to measuring etc. Another thing i wish you showed was how you knew your last pass gave you the dimension you needed for a press fit? That hydraulic ram must be putting a ton of force into seating those bushings.
13:00. that is cool how the machine uses cams to control the amount of weld distance in PIE cut... .I thought it might be controlled by computer.......great looking job Greg......
It’s not like 3D printing with metal… it’s literally 3D printing with metal. It’s additive manufacturing. Stuff like this has been around as long if not longer than 3D printing. This is the daddy of modern 3D printing. Also, they have actual metal 3D printing in the same format that you’re imagining.
Interesting to see how others do the same kind of repairs. I did one of these in pretty similar shape. Thankfully they had the dog bone pins pulled to do a true bar to bar setup. I always weld up stand offs to put the big bearings on to keep the chatter down and take bigger cuts. I always do all the welding by hand with bigger wire too. Took about a 20 hour shift to knock it out from skimming out old bearings with air arc fixing grease lines and build up faces.
Seems to me that you are one of the best in the business I love welding my dad was one of the best around doing the old school welding he started back in the 40s and was doing it for over 40 years he showed me everything I could know about welding sick arc mig it’s a really awesome thing to know how to weld it’s a great business.
I’m impressed with the Climax machine, does a great job and looks like it has come as a kit. The big blue box visible in the background. Almost all the lineboring equipment I see here in Australia is 3ph or homemade single phase. I note yours is hydraulic, Greg , I’d like to know why you selected hydraulic as the rotational force. Did the Climax come with its own power pack or did you adapt something else suitable? Regardless, it is a very tidy piece of equipment and does a good job. You’re a hand man to have around!
The base Climax kit comes with a 120v electric motor. It’s okay, but the hydraulic has massive amounts of torque. Climax sells all the stuff to make it hydraulic.
Is the new metal that was added back by layering welds as strong as the original metal that was worn down from heavy use? Or will there be flaws in the new metal at a microscopic level that human eyes can't see unassisted that will result in this having to be done again sooner than it would on a new machine? I'm currently at my 3rd job related to metal fab, but I've only gotten to see welds related to sheet metal so I'd love to know the science behind this from anyone that knows!
The weld is the same as the parent material. I don’t care how good anyone is, welding up a bore like this there will be flaws and small imperfections in the weld. But that isn’t really a big deal because the bushing is taking the load and it’s spread evenly over the bore.
Steel is pretty unique as metals go, it’s metallurgy/strength doesn’t get messed up as badly by repeated weld passes as other metals, which helps make repairs like this viable.
If your chips are turning blue, you are running too fast. Slow down until the chips turn silver. The most I ever take on a cut is .030”. On the very last cut, only take .004” deep cut. Never warm up the boss to press in the bearing. Once thembearings are under compression if you heat them you’re going to relax them and they won’t be tight enough. Call your caterpillar dealer and get the hollow 55 ton ram with the 55 Ton puller bolt. It was an issue on this job, but when you bore weld a bore with a seam inside of it and it’s full of grease. Just keep wiping the grease out while it’s welding and keep welding until you’re done. Then take your stick welder with 6010 welding rod at 130 A and burn out all of the porosity. It’s the only way.
I can only imagine how much a specialized, high quality instrument/set like that bore lathe costs. I mean, I get it, sometimes for your trade you NEED to have certain equipment so the price isn't as big of a deal breaker as it is for any random dick like me, but damn. That is an impressive piece of specialized kit. I'm sure it pays for itself pretty quick so long as you can line up the work with it, even if its worth more than I make in a year. Beautiful work, thanks for recording this and sharing it with us boss.
Speaking of being wet with 3 phase; a colleague of mine once briefly held that stuff during a work accident. Company sent him somewhere alone in the middle of the night like idiots. He was lucky to survive that and we couldn't believe that happened because he called me right after. My home was close to the shop we worked at and I almost laughed when I saw him. He was straight out of cartoons, his hair straight up, skin slightly burned here and there and the soles of his shoes were exploded, nearly gone. At that point I realized he was slightly delirious and understood why he was so calm on the phone. Luckily he ended up being alright. Remember boys, if ya don't know what it is, it's buzz!
@@gorillaau it was the only person I've known to not only survive such a shock but also without any major damage. Something must have gone seriously right with his situation aside from being there at night, without rest, dancing with satan. I quit that shithole after a couple of weeks but as far as I know he was ok. Didn't know if he sued and how did it go, I hope he did and ended up shutting down that shop. They were closed after less than a year anyway. I wasn't surprised because the management was a bunch of shitheads
Never seen these tools or this process before and it has to be the highlight of my week seeing your skills in action. Love learning and specialized tools in the hands of skilled workers and this hit all the nails on the head.
Very cool and educational to see, I saw the job at hand and thought to myself ''Man how are you going to fix that?'' and I was not disappointed by the process.
I do the same type of machine repair, but on MUCH smaller machinery. At 41:25 I was thinking, "man. I cant imagine pressing in a component so big that even a torch and hammer couldn't save me". But then Mr. Hammer showed up! and then Mr. Torch! Good to know the basics still apply to the big boy jobs. I guess that means the big machine repair guys also freeze components for interference fits, but it's probably a lot fancier than my upside-down cans of compressed air i bought at costco haha.
That is truly fascinating. It is also something I have to do for a couple of woodchippers here where the bearing surfaces have broken down. At least I can get the bits into a shop. The welder jig is superb..I expected an encoder controlled motor..so the limit switch and sector was a simple joy to see. What happened that you felt the need to move so far away when pressing the bush ? Is it just the fear kicking in. Farther away the better unless there is no option but to get closer. Anyway it's great to see and I certainly appreciate the time taken in making the video. Thanks.
Line Boring for some one like looking in from the outside is absolutely fascinating at first I thought how is he going to get the arm to the shop DUH !!! The equipment is so mobile which make it even more impressive this kind of advanced tool makes me proud to be a man ,we can make such amazing stuff the skill you have is so impressive almost as impressive as your epic truck ! I wonder how much weight is in the entire welding process it has to be a good few Kg that's a lot of metal .
Are you sure that you charge enough for your work? On the positive side you are providing great service. Your very well equipped and always seem have what you need to do the best work you can in the field. This is a tough job.
Brother, I grew up on farm where we make stuff work, worked maintenance on much different equipment, was awarded an Apprenticeship, and have been an "Old School Machinist" for many years. From farm(make this thing work now) to Maintenance (we'll make it work 'til the parts come in) to actually doing shit correctly, That was nice work brother. I understand the equipment helps, how you found that "Zero" is more of a skill. Set-up, lay-out, wisdom makes the equipment make you look like a hero......and you are!...You can do something 99.99% of the rest world can not . I hope you have a couple of young people that want to follow in your trade.
Lets be honest here. The amount of skill that it took to hold the camera, watch the welder, and hit the arc interrupt button at the same is phenomenal. ;)
I've seen it done by a team of welders in the old days. It's probably a lot cheaper this way.

I think I’d pack those bushings the day before in dry ice so they would shrink then just keep them in a cooler and bring them with you.
I agree we used to make the bushing an interference fit and shrink them in with liquid nitrogen. BUT you do have to get the limits and fits correct...

Steel is pretty unique as metals go, it’s metallurgy/strength doesn’t get messed up as badly by repeated weld passes as other metals, which helps make repairs like this viable.
If your chips are turning blue, you are running too fast. Slow down until the chips turn silver. The most I ever take on a cut is .030”. On the very last cut, only take .004” deep cut. Never warm up the boss to press in the bearing. Once thembearings are under compression if you heat them you’re going to relax them and they won’t be tight enough. Call your caterpillar dealer and get the hollow 55 ton ram with the 55 Ton puller bolt. It was an issue on this job, but when you bore weld a bore with a seam inside of it and it’s full of grease. Just keep wiping the grease out while it’s welding and keep welding until you’re done. Then take your stick welder with 6010 welding rod at 130 A and burn out all of the porosity. It’s the only way.
Always good to be busy! You hate the days when your getting interrupted all the time but that's when you know your making 🤑🤑🤑
You are using the technology available (which is practical) to its best advantage. Well done.
being that far gone would it be better just to replace the hole end? or is that a lot more work
It’s a decent amount of work and the end piece is very expensive.
@@OFW I kind of thought that, but thanks for answering my question
Don't know what you get an hr but your work an the precision you do is well worth it ! 👍👍
I can only imagine how much a specialized, high quality instrument/set like that bore lathe costs.
I mean, I get it, sometimes for your trade you NEED to have certain equipment so the price isn't as big of a deal breaker as it is for any random dick like me, but damn. That is an impressive piece of specialized kit. I'm sure it pays for itself pretty quick so long as you can line up the work with it, even if its worth more than I make in a year.
Beautiful work, thanks for recording this and sharing it with us boss.
Your a very talented man you know your trade I'd give you at a boy's all day long from a old retired welder thanks for the videos
Speaking of being wet with 3 phase; a colleague of mine once briefly held that stuff during a work accident. Company sent him somewhere alone in the middle of the night like idiots. He was lucky to survive that and we couldn't believe that happened because he called me right after. My home was close to the shop we worked at and I almost laughed when I saw him. He was straight out of cartoons, his hair straight up, skin slightly burned here and there and the soles of his shoes were exploded, nearly gone. At that point I realized he was slightly delirious and understood why he was so calm on the phone. Luckily he ended up being alright.
Remember boys, if ya don't know what it is, it's buzz!
How many days in the hospital? Sounds like a big bang, rather than a buzz. Ears might have been ringing also.
@@gorillaau it was the only person I've known to not only survive such a shock but also without any major damage. Something must have gone seriously right with his situation aside from being there at night, without rest, dancing with satan. I quit that shithole after a couple of weeks but as far as I know he was ok. Didn't know if he sued and how did it go, I hope he did and ended up shutting down that shop.
They were closed after less than a year anyway. I wasn't surprised because the management was a bunch of shitheads
@@mistaowickkuh6249 Probably everyone else in the trenches got out after you did. Walk out before you are carried out in a body bag.
awesome work! puts into perspective how much work could have been avoided with proper greasing and pre-work inspections lol!
Amazing what a small amount of us humans can do, thank you for documenting your work it is much appreciated.
Moral of this story: Don't let holes get that sloppy.
Great filming. That was a complex repair, well done.
that wasn't a bor watching you boring the apatur... what a beautiful peace of equipment and very well done sir. 👍
When he was pressing in that bushing, in know the threads on that nut were screaming! Great video!
Super awesome! I watched the whole video. Thanks for taking the time to make this video. Nice job!
Never seen these tools or this process before and it has to be the highlight of my week seeing your skills in action. Love learning and specialized tools in the hands of skilled workers and this hit all the nails on the head.
These pops when the new sleeve moves in after tons of force were present are pure satisfaction
Pure anxiety lol.
I love finding repair videos like this. I didn't even know this was a thing and it's very interesting!
Very cool and educational to see, I saw the job at hand and thought to myself ''Man how are you going to fix that?'' and I was not disappointed by the process.
Amazing skill! Fascinating procedure. I'm guessing that repair equipment, line bore, welder, press, doesn't come cheap!
I do the same type of machine repair, but on MUCH smaller machinery. At 41:25 I was thinking, "man. I cant imagine pressing in a component so big that even a torch and hammer couldn't save me". But then Mr. Hammer showed up! and then Mr. Torch! Good to know the basics still apply to the big boy jobs. I guess that means the big machine repair guys also freeze components for interference fits, but it's probably a lot fancier than my upside-down cans of compressed air i bought at costco haha.
That is truly fascinating.
It is also something I have to do for a couple of woodchippers here where the bearing surfaces have broken down. At least I can get the bits into a shop.
The welder jig is superb..I expected an encoder controlled motor..so the limit switch and sector was a simple joy to see.
What happened that you felt the need to move so far away when pressing the bush ? Is it just the fear kicking in. Farther away the better unless there is no option but to get closer.
Anyway it's great to see and I certainly appreciate the time taken in making the video. Thanks.
Great arc shots in this one Greg!
good morning from hurricane infested Orlando, Florida.....cheers, Paul
Line Boring for some one like looking in from the outside is absolutely fascinating at first
I thought how is he going to get the arm to the shop DUH !!! The equipment is so mobile which make it even more impressive this kind of advanced tool makes me proud to be a man ,we can make such amazing stuff the skill you have is so impressive almost as impressive as your epic truck !
I wonder how much weight is in the entire welding process it has to be a good few Kg that's a lot of metal .
Are you sure that you charge enough for your work? On the positive side you are providing great service. Your very well equipped and always seem have what you need to do the best work you can in the field. This is a tough job.
Можно только позавидовать технологиям, инструменту и оснастке. Высший класс!!!
Brother, I grew up on farm where we make stuff work, worked maintenance on much different equipment, was awarded an Apprenticeship, and have been an "Old School Machinist" for many years. From farm(make this thing work now) to Maintenance (we'll make it work 'til the parts come in) to actually doing shit correctly, That was nice work brother. I understand the equipment helps, how you found that "Zero" is more of a skill. Set-up, lay-out, wisdom makes the equipment make you look like a hero......and you are!...You can do something 99.99% of the rest world can not . I hope you have a couple of young people that want to follow in your trade.
in the field. savage. i've only ever done things in well equipped shops but the lure of doing stuff in open air looks sick.
Excellent work. 👍
That looks brand new.
This is one of the greatest things I've ever witnessed. Super impressive!
Look at that beautiful weather! With love from Canada lol
Very nifty feature that pi partial weld!
Love the channel man. You have some awesome and unique equipment, thanks for sharing!
I don’t what you’re getting paid, but you should double it. Incredible amount of know how,logic and grit to do this work.
That was really cool to watch how you did that. I come from a family of machinists and metal fabricators, that's why I became a carpenter...🤣
nice equip, nice skills, good job, work done, keep going! cheers from Germany
Профессионал с большой буквы и с золотыми руками!!!!
That was fascinating, great camera work and good explanations of what you're doing and why.
