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.
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
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.
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.
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 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.
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.
А если бы поставили шпонку с графита перед наваркой или еще с чего жаростойкого то вообще было бы идеально И зачем по всему валу так много шлифовать после наварки вала Размера то не будет уже 😢
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.
"Saving money," isn't that always the case when something goes sideways =) Hey, how's that Arc Captain holding up, still think it's a good machine for the dollar?
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.
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!
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 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.
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
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.
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 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 . )
Looks like a shaft from a pc6000. Curious to know which competitor 😂 Have worked with diamond grinders my whole life. We put these shafts thou hell man 😂 have had 3 in the machine shop in the past month. Something crazy to think, to stack on of these shafts is about 280 diamond blades which will run you about $60,000. but they last about half a season usually.
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
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! 😂
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.
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.
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.
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.
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
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.
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.

Kurtis and his evil twin Karl offer an ongoing master class

Watch all videos from those three channels.
Milling machine
My dad was a machinist. He passed away last August. I recently stumbled on your videos and they remind me of him. Thanks

Masters of their trade comes from decades of experience and learning from them is a rare chance that is priceless.

put a vid up and show us how its done
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.
he sure is....

You should have put it in the lathe. Grind marks on the end of the shaft don't look good.
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.
Always enjoy your videos. You are the ONLY Californian I've ever liked or respected, but I'm from Montana.
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.

woo late night upload!
“Good enough for who it’s for” - if the customer chowdered it with the torch, no lathe work earned
You make the repair to the keyway look easy, thats just your skill bro keep the videos rolling
Nice job
That’s why I love your videos, you don’t know what’s coming through the door next
Olá amigo trabalho perfeito como sempre!!!
Boa sorte !!!!
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.

Before I sound like an arrogant ass… Killer job man! Your skills and abilities to repair such a wide range of equipment is phenomenal!
Hello .
Congratulations on your great work! Technically, this is very impressive and very interesting. .👍👍👍👍👍
"Saving money," isn't that always the case when something goes sideways =) Hey, how's that Arc Captain holding up, still think it's a good machine for the dollar?
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 !
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.
I would have absolutely turned that in the lathe, instead of grinding it. You didn't even make a go/no go ring to check your work.
You don’t know what I did or didn’t do to check my work. This would not have spun true in a lathe.
@@OFW you probably would have spun a bearing in your lathe before spinning the part
Great fix. Cant expect perfection on an imperfect part. That was darn close though!❤
Easy money
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.

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.
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.
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.
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.
The customer's maintenance man ain't one.. That keyway is big enough to arc gouge the keyway and save the shaft.. A burr bit. I despise them..
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.
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
Did he just drop his grinder to the floor? Unbelievable! I guess he doesn’t care about his tools!
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.
Always interesting
👍
Been a'while...shop is new, bigger, or just cleaner. *-)
Don’t do any of this shit but love to know how things work. Love the channel.
Making a sled for the mill was smart. Nicely done all around.
Using a key way it is the weakest part of the assembly...A press fit is the strongest...
Nice work, it's amazing what you can repair when you know what you are doing 😊
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.

No, not a Union shop.
Yeessss!!!
oppsy
At least that shaft and a nice ring tone when you was chipping away at it.
Brilliant 😊😊😊😊
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.
Also welding spatter will not stick to Acetylene soot
Another solid repair, Greg!
Yeah somebody lied to you no way 80,000
Nice. Good job
Nice repair
nice welding!

What holds the work to the mill?
There was a clamp on there.
Great approach, Greg!!
You have a very nice audio on your vids!

Ran bump grinders and groovers back in the day southeast US. Lots of diamond blades. Eagle Grinding and Grooving Co.
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. 😊

Greg, late to the show, but always showing up sometime, cheers from Florida, Paul
Sometimes manual and simple is better! I thought it nice when you started with hammer and chisel!!!! Enjoy the channel!
I call those die grinders “the devils toothbrush” those shards always find the worst place to get lodged into after I’m done

Thank you for sharing, always a pleasure watch your project, I learn a lot 👍👍👍👍
That keyway looks factory made that's a job perfectly done my dad once told experience keeps the devil where he is
What a job. You have to keep your thinking hat on with this job. Never boring from where I sit
you can use mild steel wire on a shaft like this?
Yes
687 👍's up on fire welding thank you for sharing 😊
Bit rough ...
Thank you.
the ArcCaptain seems to being working great........
Someone please ,answer the damned telephone !! Good job!!!
Brilliant set-up solution to milling the key way. Genius
Sounds like you are a bit under the weather ?
Ya. I have had a cough I can’t get over.
what a fun project. always learning thanks
Good stuff
Well done
Your mission should you choose to accept it...................
