- Bone Yard Wars, would really be a cool series for a TH-cam machinist group of guys, but this video is a share on helping a customer use their own bone yard to repair, machinery they still have in use. We all save or hoard spare or extra parts and components, why should our customers be any different, reminding them they have one may come in handy for both of you.
My customer has a full crew of mechanics, so I'm just involved in the cylinder tube repair. ;{)--------
My grand father was a true black smith who fixed farm equipment blade sharpening ect his beads looked like yours [the best] and he was famous throughout the state of Idaho great video!
Top notch as always. I'm a master in my trade (automotive) but would walk away at the drop of a hat to mentor with Keith just for the sheer enjoyment of learning from him. Keith does what very few people in any trade do any more, give customers top notch repairs and saving them $ while making $ yourself and then teaching others to boot !!
43 dislikes were either misclicks or jealous hacks.
What a pleasure it was watching YOU operate and repair junk making look like new!
That was a neat repair, thumbs up. This goes to show how important it is to be precise when repairing machinery that have heavy loads.
It's nice to see somebody do a proper repair.
I've been working around some Machinery in my life with some very cobbled up repairs and wondered if I was going to make it home alive after work.
Remember folks it's others people's lives at stake, do it right or don't do it at all.
Hi Keith, I have watched you do jobs like this and others a lot of times, but there is something soothing and satisfying in seeing it anyhow everytime, thank you Keith for sharing your Repairing America one job at a time, a good old handmade thumbs up to you.
Every time, I watch You or Abom79, I remember how much fun and how satisfying, being a Machinist is. Thanks for the videos. GREAT Work !
I'm blown away that one weld holds the eye to the tube!!!!!!!!! Thank Keith for your work and great skill.
Often When i do field repairs the customer goes like, hey just fix so we can finish this job and we Will come in and get i repaired properly. Problem is they never do... And I know they wont so i try to fix it as best i can on-site. Nice work Keith.
Make a channel with a gopro documenting your field repairs man!!!

Ya temporary usually becomes the most permanent, because it's just not important until broken.
That is the most heard statement by any mechanic that works on equipment. They drive a brand new truck and all fixed up but the track hoe that pays those bills is just get it by for now. Never understood that.
It’s only temporary unless it works.
Never thought I would last the full hour but you made this interesting. Enjoyed the insights you gave and the expertise you showed. Thank you for an educational video.
So much more fun, repairing broken parts, than making new ones. And I can tell You obviously love it too. Prepping a tube and a base, - and welding them together is probably some of the most common jobs I do as a hobbyist in this trade. Always very satisfying when the two come together nice and straight. As usual - I picked up a few tips again from Your great video. Thanks for sharing, Keith!
PS: It's about time the last 3K subs show up! We all think You deserve that "button" on the wall now!
This video brought back memories of years ago when I did what you just did and also made cylinders from scratch.Thank you for the trip !
Nice job Keith, properly done and enjoyed by many of us regular viewers. Thank you.
it's a treat to watch you work.
It's great to see a master who is a total professional. You're shop equipment is well used, but it's clean and orderly which is a major plus when I look for a repair service. If you demonstrate you care for your gear, you'll likely care for my equipment.
Sheesh Keith, welding that freaking close to your chuck! NOW I'm convinced of how darn incredible you are with a welder! :D
Keith, you make this stuff look easy. Your welding is amazing. If I did it I would have welded the chuck to the pipe, burnt through two or three time, and set the machine on fire.
working as a welder in a bush camp all my life for a big company I se to raid the bone yard all the time just as you are doing, just to get the machine going again until new parts can get trucked in in a few days or weeks, the bone yard saved many machines and pissed off the night shift guy on a Friday night as id have it up and running for there shift, aaw now they cant leave for the weekend trip home with pay, they had to work now
Another great repair from the man.
"Just a quick fix to finish this up and get back to the yard" always turns into "Well, it's working, so it doesn't need fixing any more" when you get the damn thing back to the yard. (And then it breaks again, and it's suddenly top priority to get it sorted, rinse, and repeat.)
Best youtuber on line, you show us how it´s done + explain what you do underway.
Big props to you Keith, thank you for the time you put in to this..
Your Job Shop experience is amazing Keith. You tackle the weirdest things with just "meh" it'll all b fine. Wow. Thanks for showing us the proper way to set it up.
I CAN'T SAY IT ENOUGH!!! WHAT A BEAUTIFUL LATHE!!!! NOT JUST ANYONE HAS ONE OF THOSE!!! IM HOOKED, NEW SUBSCRIBER!!!
Thanks for the up-close look at the repair. Really interesting to see the root cause of that leak and how you corrected it with proper weld prep.
Pretty steady hands those jaws were mighty close. Good job.
Thanks Keith, I am a big fan of repair over replacement :)
I watch your awesome videos for that single tidbit of technique I never learned in my non machine shop self teachings
Thanks for all the explanation as you go it’s very helpful
I was an equipment operator and a shop/equipment manager for a company and many times preventive maintenance is only oil and filter changes and a few shots of grease, you're told to run everything else until it breaks. This is not good when you are an operator or a manager that wants to do the right thing by the equipment and repair and maintain the equipment correctly. I can't tell you how many times I was told too just get it running and fast and we will fix it right when we get back to the shop. It never seems to happen and the quick patch only last so long and makes the operator or mechanic look bad when it's not their fault. So many times when I or another mechanic was trying to do it correctly, when we did have maintenance down time I was not allowed to spend the money. It's like that for a lot of operators and shop/equipment managers, we're only allowed to patch it just good enough even when we know it's not going to last. It gets damn old after a while and you eventually move on.
I'm in the same boat.
I actually got injured in an accident and I'm disabled now. I've been going back to college and should graduate with a business degree this fall. I am also working on a degree in Unmanned Aerial Systems Aviation at the same time and should graduate from a different college this spring. I just want to get back to work and I needed more education because of my disability I will no longer be able to operate heavy equipment or do any mechanic work, lost my CDL also. It was a career changing accident, I just refuse to give up and stay home on the couch. Still have to have the occasional surgery but I keep on going. Watching videos like Keith's and others like his relaxes me and relieves the anxiety and helps me forget about the pain, better than a pill lots of the time.
Was the same story for me doing building/factory maintenance. I always wanted to fix things the right way, but production couldn't be shut down, not even for safety reasons (good luck finding a manager that would admit to that one!). The scheduled shutdowns weren't much better, we had no budget, no support, no schedule, and no help.
Good luck for the future ecleveland1, very sorry to hear that you got hurt. Your story reminds me of when I worked at an iron ore mine here in Australia, they often had no time to fix a machine properly, but had plenty of time to fix it time and time again. You have just reminded me of how frustrating that was. I think that it happens more now that bean counters and lawyers have the biggest say in how any business runs.
I just had this conversation with my operations manager, could rant for a few paragraphs.
Id be afraid of all the spaltter I would get on the lathe, Id probably have to grind down the jaw to get the chuck open again (" Good job , as always!
Oh My. This brought back memories of when I used to do this as a machinist. Great video. Keep up the great work.
I tip my hat to you for making an extremely well done video. The commentary you provided was to the point, concise and contained lots of useful information. It shows that you have great skill in the work you do and that you enjoy it very much. The lighting and positioning of your cameras is excellent. I am most impressed. I used to manage an NDT laboratory and have some knowledge of magnetic particle inspection, industrial X-ray, etc. The lab I managed also did chemical and analytical work on pipelines, oils, bridges and such. Keep up the great videos.
Being a pipe fitter and welder for more than 30 years, you would be surprised at how many times I have cut out old high pressure piping and found weld joints that where just butted up together with no bevel or weld prep as you say. Just a simple single pass over the two pieces. Scary to think that some of these joints had 300 lbs of steam pressure behind them for years.
Great repair video! Attention to anyone looking to improve your repair welding skills: Coming from a pipefitters apprentice, on the welding aspect, 3/32" 7018's would be more controlled with a smaller bevel on the end of a thinner tube. And if you need to make an extra cap pass you can. But that smaller rod would fit down in the bevel a little better. It could potentially help with penetration because your able to get down in the bottom of the bevel. Also with 7018 on a restart, strike the rod ahead of where you'll be starting the puddle, long arc slightly back to your starting point, get your puddle started and then hold a tighter arc. With leak proof, seal welds, this will prevent leaks on rod restart areas and porosity. Just some things I've learned from making xray quality pipe welds. PLEASE: anyone who will be making potentially critical/ potentially pressurized welds, please spend your time practicing and doing things properly. Get some proper supervision. Keith, definetly don't take this as any kind of challenge towards your skills. You have some incredible skills that can only be learned by hands on after many years. Just some food for thought for anyone who is learning how to get better at welding! Check my Instagram out @reynolds_er70s6 and message me on here or on Instagram with any questions!
The process you've used used is exactly the same as making custom length driveshafts. Just picture your cyliner clevis end as one half of a "u" joint et-voila! The final procedure being to back off the tail stock slightly, run it at a few hundred rpm with a piece of chalk held to mark the out of balance condition on the run-out then tack-weld a washer to the outside of the shaft to add balance weight. A few times of doing that with various sizes of washers and people get very good at balancing a school bus length of drive shaft that can be run up to high rpm's with no vibration.
Marvellous!! I wouldn't weld in my lathe chuck but I'm not as good a welder as you yet! Great video Keith !!!!!!!!
Thats a nice job you did there, You can tell how good a guy is at welding by how the slag either peels off or practically falls off when you touch it with the hammer, that spot must of been the poor start on the first rod. I can weld pretty good one handed but I'd of probably welded that cylinder to the chuck trying to turn it with the other hand by now L.O.L.
That comment below about pressure testing works good in a factory setting , But I know from my experience out in the field or in the repair shop, it gets fixed and straight back to work . If all that times spent on testing if you can't do it in house, half the jobs the machines doing would never get done with machine downtime while running around. Thanks for sharing the repair with us.
What factory have you seen that isn't a chop shop ran by operations idiots that don't know what maintenance is aside from guys that just spend money and shut down production?
Never seen this stuff done before - ive never used a lathe or welded but youve got me interested now. Great video.
Really enjoyed this one Keith. Thank you for putting this up.
I am sure other folks do the same thing I do. When watching a video of welding, I always close my eyes and look away when you strike a arc. Habit I guess.
I worked in a cylinder shop for years. probably did the same thing to thousands of cylinders.
My favorite video of yours so far and I've seen many. The picture quality is great, especially the welding portion. The editing for time was great, so we also got to see the whole job in an hour though it must have taken you a lot more.
good job Keith. Nice to see...
Fantastic video, Keith, top notch skills on display. Now you just have to go back to 21:38 - 21:41 and create an endless sound loop for those "other" times. Always great to watch your vids, thank you!
Nice repair! Since near day one I too have had my Bernard twist lock whip to use like you have for secure rod holding and positioning and lighter weight for certain jobs. Surprised I very seldom see one used on YT welding channels but know may old timers in the field that have one on their truck when needed. Your hyd. tube repair also shows informative practices when welding drive shaft tubes and yokes. Thanks, Ed K. Cleve. Oh.
I've had to do the field repairs on cylinders when the factory weld cracks just to be able to move the machine. I put a vacuum on the cylinder, use a grinder to find the crack and pre-heat the area. I've had many of these "temporary repairs" last for 5 years. I noticed that you didn't pre-heat these before welding like you do in the other videos I've watched. The heavy end caps suck the heat out of the weld quickly. The factory welds are often machine welded. I've seen leaks that you can't find with soap and 160 psi air pressure but they spray when the hydraulic pressure gets up to 2400 psi. If you measure the diameter of the tube, it increases under pressure, especially with the 4000psi and higher systems in use today. That stretching leads to cracking with enough cycles. The base pass seals the weld but the overpasses control the cracking from expansion better.
Hello Keith, you do a nice job with the 7018. You burn it nice and hot! All the best, Edgar
Must be Halloween coming up, Keith is fixing Zombies with parts from the bone yard! Nicely done.
It's like Frankenstein building his monster.
Nice job on the repair. Thanks for sharing.
Taking a leaf out of Abom's book with this one, Keith.
Enjoyed watching this eating pizza, passing time before my night shifts start. Thanks for sharing! :)
13 minutes from release of a 1 hour video and 23 likes. you just know it's gooing to be good :)
And this is a reason you are the king of the 4 jaw!
you got that right, it is called production for that week, patch it and get it back to work, arc air it open and weld it up, but open all the way around and weld all the way around, many just weld hot pass on top of the weld were the crack ir and never cut it open, it don't last 1 shift doing that.. then in spring when thing are shut town for brake up everything is rebuilt and repaired righ, when a crake comes in them welds or fittings you must cut it wide open all the way around and hit it with brake clean to get the rest of oil out of it, weld right around the whole thing, the high presser in them crakes a fine crack all the way around, and if you don't do them right it will be back in, a fast air arc in the bush and welded up just to get it back to work, but you are back many times doing the same patch as the oil is in it when patching and it keeps cracking past were you stopped the weld or the weld cracks were oil was
Great video and got a smile or two keep up the great work David from Iowa
Thats a common repair down here in Florida, I have never seen guys beat on machines like they do here. Great video as always Keith.
You guys need to check out the logging industry in British Columbia. The motto here is, "if it ain't broke, break it."
Gallagher Metal Works we call that incompetence up north here and fire the operator then sue them or they employment agency that sent them referring them as ‘professionals’. My machines are 38-84 years old, work hard daily and are daily maintained. Operators prove themselves by maintaining for six months to prove they know every machine
You look like a friend of mine. We are both carpenters, but I'm the one that tries to add different skill sets to my bag of tricks. Love your work and subscribing! Keep up the excellent work!
I really appreciate the opportunity to learn from your experience.
At 9 min with the shot down along the tube, it looks like that tube is bright yellow hot. Welcome to Abom country, Keith!
To start off you can't fix a crack leak with weld as seen in your video. To help your starts with 7018 rods start about 2 in. ahead in the grove and come back to your start dragging the ark it lets the end of your rod to get up to temp for a clean start, it helps to reduce porosity with practise you will not see where your second start is. You could use antisplater spray used for mig welding to your chucks its not 100% effective. I would build a turn table for welding up items not in your lathe when you wrap aground cable around you are turning your head stock into a magnet and will collect metal dust inside your chuck and headstock. I have seen what happen to pipe rollers in the shop I have worked for.
Personal preference of control has to do with not having to change stance to control the movement with two hands.
The second cylinder with the weld on weld, you mentioned that the end cap was not square with the cylinder compared to the previous. I bet you that’s why it was welded because it has been stressed, pulled off square which caused the weld to crack and leak.
Though some of the techniques are seen here, what I would really like to see is some driveshaft repair/modification. Seeing how to get around the problems and hazards of working on things that are thin walled and/or longer than the bed of the lathe. I've done a fair amount without a lathe, the result has always been 'rumbly' without a lot of fussing (trial and error) to get things balanced enough so you're not wondering if things are going to break apart while driving down the road... can't say I've come across anyone covering that specifically.
Driveshafts need dynamic balancing, it's a specialised field. And custom driveshafts just aren't that expensive to have made up, certainly cheaper than a driveshaft letting go and shredding your car up...
Balancing isn't just about making it quiet and smooth, there are several orders of magnitude higher balancing needed than what a human can discern, otherwise you end up with short UV joint life, extension housing bushing wear etc....not to mention correct and ACCURATE phasing of UV joints.
This really shows how important it is to always have a good prep or preliminaries to get a yard long bone, or, is it, a bone a yard long .... lol
What you do in your yard is your business. We’re not here to judge you. 😂
Welding is 90% prep and the rest is pure skill!!!
Lower the tone why don't you

What ever you charge people for your services is to little! The years of experience that allow you to repair the vast variety of projects is invaluable. 🙂🙂
Not easy welding with one hand while turning the chuck. Great repair!
Thanks Keith, I enjoyed this repair, a little something off the beaten trail! Could be next bash will be a 4 jaw- welder up competition in the works?
Looking at the throat on your lathe, I probably would have sawed the cylinder off about 12 inches from the mount swivel and chucked that up. Then I'd know my depth of cut for separation by measuring the tube wall. Also would have put in the half V for the welder while cutting the tube away. That's just me though
Love to see things do right.
“Hello thinness my old friend...” you know the tune? Boneyard hydraulics.. ya I know that game...lol
That is scary bad welds maybe more work coming your way. Clean parts and bone yards take down cylinders. Not many repairs of hydraulic cylinders on TH-cam man it's good to see it. Awesome SMAW repair o the cylinders Keith. Zero tolerance on leaks and hydraulic leaks with bad welds.
nice repair. Looks like it was off a case e series or older backhoe. If the operator isn't paying attention you can really jam the boom cylinders into the stabilizer because they are mounted on the outside of the boom. love your videos. I've learned a lot from you already
You did a great job I'm surprised you welded next to your prize Chuck I would have heated the end of that tube and cooked out any residual oil would make for a better weld I really enjoy your videos
Nice work
Keith, Just an observation -- do you (or could you get) an el cheapo automatic darkening helmet for your camera. There were places where it was overloaded(?) by the brightness of the welding. Your camera still did a pretty good job automatically darkening, so we could still see most of your welds and the "cracks" as you approached and welded over them.
Great video about this type of repair! I'm sure that many/most of us learned something from this video.
to mr. demar who rightly said the barrel is bent.. that is what the video did with bone yard parts...
Good engineer!
Nice job but i wouldnt have welded stright up and down i would have been a little from the top to let the slag run out of the way instead of pooling and affecting the weld
When I saw you setting up to weld on your lathe ,it startled me.....at first. I saw your precautions and realized the generation of your equipment, then relaxed. Just so you guys know, on some equipment ,especially equipment with computers and transducers (especially high dollar modern cars and trucks) removing the power source is NOT enough due to whats called eddy currents. When you pass high current through steel or cast iron ,your also creating magnetic waves thru the metal ,on some electrical components ,this magnetic wave can be converted back to electricity. Modern electronics are often extremely sensitive to very low voltages . They have to be .Some modern equipment in fact ,always has a small circuit always in operation and operate on "flea power" to have the computer turn the equipment on via solid state relays etc. It is not disconnected via a proper toggle switch.You can pull the plug....but its still connected ,waiting for a little pulse of electricity. This is why cheap Chinese digital calipers always run the batteries down...even when you "turn them off". They are OFF....but not really. Just wanted to same some hassle for everyone ,especially if you have added aftermarket digital stuff to your old machines.
My fear would be creating an arc in the bearings, hence i never weld in a lathe.
And the good thing having the aluminium spacers is that when weldin there will be no arcing/spot welding between jaws and work, Should have used a bit of anti-spatter spray on the chuck though
Does electrical tape over a used bandaid count? sometimes they just don't stick! loved the analogy.
I agree it was best to weld it in place on the lathe but I was thinking it might have been a good idea to spray your nice chuck with some welding anti-spatter spray, though it looks like you didn't have any spatter anyway.
excellent, beautiful job
what he is failing to say is all the end caps have a machined lip that fits up in the center of the barrel tight with a step cut into the welded side of the end cap, you follow that line in until it opens the 2 metals, a fine line will appear ,, and on the end cap clean up the fit, cut in your bevel at the same time ready for weld
Great repair Keith!
I believe that an error was initially made: the micrometer, used for centering the cylinder , was positioned too far from the face of the spindle , but where the tube was already bent , so that even the turning will be not centered . the consequence will give that , at 18 '56 ", the internal face of the cylinder will not , necessarily , be in line with the previously turned circumference .
Well done. Thanks for the video.
First time I saw your channel. I like the lathe. Was a bit concerned when you welded on it even with the bed protection but you did great.
I bet I would have welded that cylinder on to the chuck. No problem.
But it did gave me the idea of welding up a back plate to fit a big chuck to my little lathe :)
I agree with you ... I have been good at either welding things together that didn't need to be or getting a lot of splatter on things i didn't want it on. I would have never welded that close to my chuck without protection ... but he made it come out great!! shows his great skill in so many areas!!
oh my god, would I want to see an actual "scrapyard wars" with like the production quality of forged in fire. Like a few machinists are allowed to get to know a lathe and a mill and then they get a Job and they are scored on surface finish and time and stuff.
so glad to see you using 1018 stick rod, unlike all the clowns on here with there wire feeds hot boxes,, not how its done, I use to love doing them all day long
You obviously never have worked production mig processes are a must for that yes stick is a solid process for a smaller shop
@@carolshawol6699 in my 59 year as a licesed welder i worked many production lines mig welding, stick welding. robotic as well a number of years working in huge bush camp welding on heavy equipment. this video has nothing to do with a production line or sand blasted clean new materials
And there I was, wondering what he wanted with the "belt sander"... (bell center)... got to get my ears calibrated!
The repair was interesting . Thank you for the video.
my thoughts on it, knowing that you centered the tail stock end that the chuck end was not axial with the axis of the lathe as the ram tube was bent. It would only have been axial if the tube was straight.
I would have thought that the tube would have been cut off before the bend and then machined square using a follower on the stubby length of tube.
once square with the axis of the lathe then the tube machined off to get a square end at the ram base.
possibly a lot more work for no great improvement.
thanks
Good work!
Adam better see this you working on his cup of tea😂😂
He's definitely after Abom's channel. First the glory and now the jobs. ;-)
next thing we know he get his head shaved. :-)
15 years of naval ship repair, I was working on various hydraulic systems before Adam was going to school. I love the videos that Adam brings to the Tube, reminds me of those days in the early part of my career. I would suggest to anyone, that Adams channel would be the go to channel for the heads up on hydraulic machining tips. I do enjoy the pun! LOL ;{)------
Great video.....Thanks
Used to do this every day at the hydraulic shop that I worked for !
Also, customer is very, very lucky that cylinder didn't blow apart and kill someone. Improper welds on pressure vessels kill folks with disappointing frequency. Even the welds you did should be tested properly (brought up to full pressure with the cylinder in a safe location behind a blast shield / under water) before use, in case there's interior porosity that would weaken the weld but not show up on the air pressure test.
The shop I welded the cylinders replaces the seals and pressure test the unit before it is sent out. ;{)-------
you sir are the mister rogers of the fab world. as usual you gave me a long relaxing time. just simple machining and welding. no trump bashing or politicking . always a pleasure.
My silly trick for blowing out the ways: position the shop vac hose to suck up what I'm blowing.
Worried sick about the chuck during the welding op
Nice video and you obviously know what you are about on a lathe. That said, I hate to see a watch worn around a machine tool.
