I like the way you guys mention things you have learned from other channels. I learned the soot thing when bending 1" aluminum torsion arms for Sprint Cars years ago . Yourself, I C and CEE are all nice to learn from.
I had to roll a few aluminium wheels and a piece of wood Is a great indicator of the material being at the right temp as it skates along the aluminium.
Even better than just a mechanic. He’s a welder machinist mechanic. Not just that a mobile guy to who line bores in the field not just in a shop. Heavy duty repairmen who can do all 3 trades and are skilled are pretty rare in this industry.
I can’t tell you how many key ways I’ve had to weld up. My company had a very well stocked machine shop with great machinists. Most of the time we welded the entire key way up with weld and re-machined it. But there were times when I did what you just did, especially on shafts that were not real critical. I’ve also had to weld the entire shaft from one end to the other so that it could be machined back to its true size. This was done with rotators and submerged arc welding. I don’t comment much but do enjoy your videos. Keep them coming because it brings back memories of my welding for 40 years as I have retired.
I had an engineer customer who designed and built tuna/fish processing factories all over the South Pacific. Tuna factories! It's amazing how many talents people possess to make our world go. Hell, I'm a barber/stylist. I didn't know how valuable I was to others till I retired. My customers were devastated. One started crying! Wha'?
I work with these shafts and cut key-ways in them steady at the mill. Just a heads up for next time at 13:00. Your buff out was fine but just keep it on the weld and key-way that shaft needs to be perfect otherwise. Dont touch any other part. The guys assembling the sheave will emery cloth any high spot down to get the maximum area contact fit. I have cut/nicked shafts with torches, grinders and gouging and its always important to just address the one spot, any more and you risk the coupling or sheave loosing grip on the shaft. Cheers man, love the videos
When I was watching, I said out loud 'darn it' when you announced that you weren't going to turn it in the lathe. 😂 In all seriousness, I really enjoyed watching your repair job. You really hit the nail on the head with this one! Not only were you able to efficiently repair the shaft, but you were also able to communicate your process effectively through a concise video! 👍🎉🎉🎉❤
Nice to hear you support Izac from I.C. Weld. I also subscribe to his channel and apart from the vast amount of old school knowledge he has in that brain of his, not to mention his sense of humour, teaching his son to follow in the old man's footsteps is a wonderful thing. How you dealt with welding up the keyway was epic. Personally, I would have used stick weld, but hey, each to their own right. Mind you, I would have cleaned everything up as you did considering the spindle is not micro precise. A job well done, thanks, mate.🤘🇬🇧🇺🇦🇮🇱
I'm not in your industry. I just do some hobby welding but your channel is fascinating to me. Great work and I love watching how you tackle different problems
Very creative/ innovative milling. I watched about 10 of your videos to understand that your variety of skills is “next level “. And your finished product is as close to original as anyone can possibly get, especially in the field. True professional.
Greg; used Cubitron grinder disk for the first time today per your recommendation, purchased in your amazon store. Absolutely Amazing!!! The best grinding disk ever. Thanks so much./ jim
Very interesting video. I have a small chipper/shredder that has this same problem with a worn keyway and I need to figure out how to try to fix it. It would be more hassle and more money than the machine is actually worth to pay to have it fixed, but, I've had it for decades, it works very well, and I like to keep old, quality machines working for as long as I can. Thanks for the ideas.
Filling the torn keyway is fine, but after welding up the keyway, I would have rotated the shaft 180 deg. and cut a new keyway. That's how we used to do it, no issues regarding shaft integrity.
I use the smoke trick as well, I heard that once it burns off it’s about a 400° preheat. I have one of them arccaptain welders for small road jobs and it welds pretty nice for a cheap welder.
You know what I love about watching these videos, I learn through others experiences what not to do like what he said at the end of the video and the part probably not being true I like taking in those little tid bits of information it does help when I run into other scenarios I remember what someone else did or didnt do and make hopefully better plans.
Nice setup and result OFW! You might suggest attaching that key to the shaft with a couple socket head screws and tapped jack screwhole to your customer.
I built a 550hp 350 chevy. all the right parts. the HotRod book I used said that the bolt to hold the harmonic balncer on the crankshaft was unnecessary, save some weight. So I did.. Well it worked loose. Everything was spun balanced. I dropped the crank and left the conrods inplace. No Easy Task. Then I took the crank to someone like you and had the crank end flame welded by some one like you. To replace the crank was cheaper but this was a 7800rpm engine. (sidebar, I didn't use a cam button and so the cam walked which in turn wore, elongated, the cams distributor drive gear, producing an interesting ignition advance effects phenomena on the distributor. So I replaced the cam after 700 miles. live and learn. use a cam button and use the harmonic balancer bolt. this was over 40 years ago . )
Before Road Safe bought IMS I had the wonderful pleasure of maintaining and repairing the fleet of paint trucks, grinder trucks, and the cone trucks. Yes that shaft stacked full of diamond carbide cutting heads is well over $80k!! Just as a comparison. A single truck in the fleet, had 3 auxiliary engines, plus the coach engine. Grinder heads and paint tanks. It could grind the rumble strip and paint the yellow and white lines simultaneously. That vehicles build cost was $2mill.
I think it's best for you to repair the damaged area and then change the position to process this keyway. The damaged area has undergone thermal deformation, and its strength will decrease.
We used another trick, take a piece of copper or brass the size of the keyway and weld using it as a dam. Saves a shitload of time, we did it on a mesh welder and didn't even have to remove the shaft. Used a crayon on the shaft and slid the taperlock on till it bound, so we found the high spots and with a grinder/flapwheel then a file. After several times we got it done, we got it down very close to round, less than 0.005" runout and less for the overall diameter.
Another fine example of why one calls the experts and not do it ones self. I have the problem of a new reman sitting in my garage for my wife's SUV. I'll let the best mechanic I can find do the job, pay a fair price and save myself a world of hurt by doing myself. Common sense I say, is the best option. Besides, if I screw it up I'll never hear the end of it! 😂
soot is a good indicator of when aluminum has reached the annealing temperature. soot it up and heat it until the soot is gone. got taught that by Charlie Rainville of IMSA fame, 1978.
They use those for grinding concrete and asphalt pavement for rideability, its not for milling asphalt. It does cost a huge amount of money for that stack of grinding wheels. Last set I remember dealing with was about $84,000 to replace them.
They definitely know how to use it, but they usually use an impact and when it doesn’t move, they keep impacting so it strips the holes out or breaks the ears off the bushing.
most sheave that I have worked will are cast iron. They are very expensive but if needing one off just cut a groove with a big 6 or 8 inch grinding when and throw a chisel and crack it off shafts are expensive and take time to replace if you damage it.
Taper bushings have a second pair of threaded holes that the clamping bolts get put into and that separates the taper from the hub. Why did they not do that?
@@OFW I am glad for you that you got the work, but there must be ways to drill and tap new holes to push in or use a puller with bolts in new threaded holes. The carnage here and destruction of the timing cog pulley is really disturbing. Do you think alcohol was involved?
@@2OO_OK honestly I don’t doubt it. This type of repair is common from this customer. I have done a lot of repairs that could have been prevented. I have made suggestions on things to change and it never changes.
@@OFW So you have the best of both worlds. You have tried to help them so your conscience is clear, and you get regular work and a source of content and amusement for your videos. Win - win!
I have seen people claiming to maintenance mechanics just struggle all day with QD and SD taper bushings. And I have seen them do this a time or two not able to break the taper lock then goof it up with a torch. Typically using a torch to heat up sproket or gear would break the locked hub enough to separate. Or take some 6 inch wedges and put them between the hub and sprocket would sometimes separate the two halves while heating the sprocket. My only concern would be the circumference of the shaft not being in tolerance within speck of the hub. Goofups always allow to skilled mechanics shine.
Very nice job on that repair. I've done similar work over the 48 years as welder. It's alway a pleasure to watch your vids, I always learn something and just wanted to thank you for making the video's. Question, are you a union shop as other vids you say you have apprentices. Im just curious .
I have a unpowered bridge crane over my mill and lathes that can lift #2000. On longer pieces I take all of the weight off the outboard end and the bridge follows the mill.
Wow they cut the pulley / sheeve some of those are in the 3 to 5 k and hard to get hope it wasn't that expensive, had to do many times on big Peterson and Vermeer grinders
Thats pretty much what i would have done minus the mill since i dont have one. just stack welds the grind and file to shape. Would have taken a bit longer but hey it would have worked
I used the saying when the customer wanted a quote and they didn’t like the quote and they say that they can do cheeper! My reply was pay me Now or pay me later it’s going to be more expensive later!
My dad was a machinist. He passed away last August. I recently stumbled on your videos and they remind me of him. Thanks
I like the way you guys mention things you have learned from other channels. I learned the soot thing when bending 1" aluminum torsion arms for Sprint Cars years ago . Yourself, I C and CEE are all nice to learn from.
Kurtis and his evil twin Karl offer an ongoing master class

Watch all videos from those three channels.
I am 61 years old. Been a pipeline welder my whole career. But I would give it up to work alongside you. You are a great mechanic.

I'm looking at the carnage, all that comes to mind is, 'someone wanted time off to go hunting!'
Best wishes from the far North.
Nice job
That’s why I love your videos, you don’t know what’s coming through the door next
You follow Issac too…he’s cool, funny and a good welder. His weld beads are not as good as yours, but close. You have talent!
Issac's cutting torch work is some of the best that I've seen. I can't understand why both of their channels don't have 500k subs.
Brilliant set-up solution to milling the key way. Genius
I see why machinest are a dying breed. Y'all always end up with the "saving money" jobs. Good job man.
Outside machinist used to be a job title.
Making a sled for the mill was smart. Nicely done all around.
Filling the torn keyway is fine, but after welding up the keyway, I would have rotated the shaft 180 deg. and cut a new keyway. That's how we used to do it, no issues regarding shaft integrity.
What a job. You have to keep your thinking hat on with this job. Never boring from where I sit

Isaac is a solid welder I started using his acetylene trick too on chrome really makes a difference and is fast and easy to do
Shoot, alum foil and old leather sleeves. The 7/70 torch pressures work good to but add up by the end of the day.
Another solid repair, Greg!
Nice setup and result OFW! You might suggest attaching that key to the shaft with a couple socket head screws and tapped jack screwhole to your customer.
Hello .
Congratulations on your great work! Technically, this is very impressive and very interesting. .👍👍👍👍👍
Great fix. Cant expect perfection on an imperfect part. That was darn close though!❤
Great approach, Greg!!

Before I sound like an arrogant ass… Killer job man! Your skills and abilities to repair such a wide range of equipment is phenomenal!
I think it's best for you to repair the damaged area and then change the position to process this keyway. The damaged area has undergone thermal deformation, and its strength will decrease.
put a vid up and show us how its done
Greg, late to the show, but always showing up sometime, cheers from Florida, Paul
Tidy job that young man, well done!
Thank you for sharing, always a pleasure watch your project, I learn a lot 👍👍👍👍
Sometimes manual and simple is better! I thought it nice when you started with hammer and chisel!!!! Enjoy the channel!
Olá amigo trabalho perfeito como sempre!!!
Boa sorte !!!!
Don’t do any of this shit but love to know how things work. Love the channel.
Nice work, it's amazing what you can repair when you know what you are doing 😊
what a fun project. always learning thanks

woo late night upload!
At least that shaft and a nice ring tone when you was chipping away at it.
That keyway looks factory made that's a job perfectly done my dad once told experience keeps the devil where he is
Great job on fixing that

Glad to ser you using good straps.
I didn't notice any clamps.
What holds the work to the mill?
There was a clamp on there.
soot is a good indicator of when aluminum has reached the annealing temperature. soot it up and heat it until the soot is gone. got taught that by Charlie Rainville of IMSA fame, 1978.
You have a very nice audio on your vids!
Looks clean !
Looks pretty good boss
2:51 hey brother, not here to talk shit I’m just curious, would a needle scaler have worked equally well as a hand chisel + die grinder?
It would be similar to the chisel but a die grinder was necessary to get it shiny.
They use those for grinding concrete and asphalt pavement for rideability, its not for milling asphalt. It does cost a huge amount of money for that stack of grinding wheels. Last set I remember dealing with was about $84,000 to replace them.
Nice work.... Great fit !
you can use mild steel wire on a shaft like this?
Yes
I have busted key ways on my equipment over the years but never made repairs because the shafts were hardened. I just assumed it would never hold up.
Nice Work. You show them how to use the jacking screws on the QD bushing!
They definitely know how to use it, but they usually use an impact and when it doesn’t move, they keep impacting so it strips the holes out or breaks the ears off the bushing.
Nice repair, Greg! If that job required it, could you have used your Climax gear to machine that shaft end true?
Technically yes, but I do not have the OD cutter yet for the climax.
At 2:18, I felt an urge to start meditating... ;)
most sheave that I have worked will are cast iron. They are very expensive but if needing one off just cut a groove with a big 6 or 8 inch grinding when and throw a chisel and crack it off shafts are expensive and take time to replace if you damage it.
Nice. Good job
I believe that customer would have saved himself some money by having you come out and do the whole job rather than trying to save a penny !
You should have put it in the lathe. Grind marks on the end of the shaft don't look good.
Nice job man!
Been a'while...shop is new, bigger, or just cleaner. *-)
the ArcCaptain seems to being working great........
Take care of your shaft you guys.

Question, are you a union shop as other vids you say you have apprentices.
Im just curious .
No, not a Union shop.
“Good enough for who it’s for” - if the customer chowdered it with the torch, no lathe work earned
I have a unpowered bridge crane over my mill and lathes that can lift #2000. On longer pieces I take all of the weight off the outboard end and the bridge follows the mill.
Nice video, thanks.
Don't you clean the weld after doing it with a wire wheel to remove the slag inclusions
There's no slag with hardwire. E70s6
OK great. 😊
Always interesting
Morning coffees on!! ;-)!!
Also welding spatter will not stick to Acetylene soot
S45c???
Nice repair! What filler metal did you use? Thanks
Er70s6
Wow they cut the pulley / sheeve some of those are in the 3 to 5 k and hard to get hope it wasn't that expensive, had to do many times on big Peterson and Vermeer grinders
Thank you.
That's a bad day when you realize you torched the keyway.
It usually came with 3 days off. So only the brave would volunteer to cut a bearing race or coupling half off a shaft.
Thats pretty much what i would have done minus the mill since i dont have one. just stack welds the grind and file to shape. Would have taken a bit longer but hey it would have worked
Nice Work
Someone please ,answer the damned telephone !! Good job!!!
Good stuff
I used the saying when the customer wanted a quote and they didn’t like the quote and they say that they can do cheeper! My reply was pay me Now or pay me later it’s going to be more expensive later!
Sounds like you are a bit under the weather ?
Ya. I have had a cough I can’t get over.
I call those die grinders “the devils toothbrush” those shards always find the worst place to get lodged into after I’m done
