[@MikeKincaid79]

My dad was a machinist. He passed away last August. I recently stumbled on your videos and they remind me of him. Thanks

[@Tinman-dm4cx]

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.

[@jamesriordan3494]

Kurtis and his evil twin Karl offer an ongoing master class

[@costaht]

If you like machining too, I recommend abom79. His videos are therapeutical 😅

[@rogerhutchings5811]

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.

[@jamesdegraff]

Watch all videos from those three channels.

[@richardbunch5160]

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.

[@frank-t6857]

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

[@GeneralSulla]

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'?

[@glenngosline1710]

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.

[@ypaulbrown]

he sure is....

[@DanielOzark]

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! 👍🎉🎉🎉❤

[@MrRebar15]

*On Fire Welding* Bravo well done. always a pleasure to watch. Thank-you sir for taking the time to bring us along. GOD Bless.

[@boogiewoogiebubbleboy2877]

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.🤘🇬🇧🇺🇦🇮🇱

[@christopherw4527]

Always enjoy your videos. You are the ONLY Californian I've ever liked or respected, but I'm from Montana.

[@garthadams9765]

You make the repair to the keyway look easy, thats just your skill bro keep the videos rolling

[@terrminatoragain461]

Nice job That’s why I love your videos, you don’t know what’s coming through the door next

[@cheeseymccheese7249]

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

[@robinjchambers845]

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!

[@jamesdrake2378]

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.

[@woodartist2021]

Another solid repair, Greg!

[@vicchiapetta4166]

Great approach, Greg!!

[@carlthor91]

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.

[@johnbichell8023]

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.

[@intensemojo]

Making a sled for the mill was smart. Nicely done all around.

[@jeffsimonar7161]

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.

[@jmckittrick1]

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

[@frfrpr]

What a job. You have to keep your thinking hat on with this job. Never boring from where I sit

[@brian_2040]

I see why machinest are a dying breed. Y'all always end up with the "saving money" jobs. Good job man.

[@afish43]

Outside machinist used to be a job title.

[@michaelschulz4317]

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.

[@Gazman110]

Brilliant set-up solution to milling the key way. Genius

[@johnvalencia7488]

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.

[@user-yc7nv2qx2n]

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.

[@SHADOW.GGG-]

put a vid up and show us how its done

[@GatorsNest]

Great fix. Cant expect perfection on an imperfect part. That was darn close though!❤

[@jimyoungquist1687]

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

[@MBwelding]

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

[@dwarnermg]

Shoot, alum foil and old leather sleeves. The 7/70 torch pressures work good to but add up by the end of the day.

[@anthonymarino4260]

what a fun project. always learning thanks

[@IrnDsl69]

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.

[@IrnDsl69]

Before I sound like an arrogant ass… Killer job man! Your skills and abilities to repair such a wide range of equipment is phenomenal!

[@sackvilleweldingservices]

Tidy job that young man, well done!

[@user-vy8lp1zv8z]

Nice work, it's amazing what you can repair when you know what you are doing 😊

Olá amigo trabalho perfeito como sempre!!! Boa sorte !!!!

[@carloskawasaki656]

Thank you for sharing, always a pleasure watch your project, I learn a lot 👍👍👍👍

[@RestorationVideo]

Hello . Congratulations on your great work! Technically, this is very impressive and very interesting. .👍👍👍👍👍

[@rebel3353]

woo late night upload!

[@mjm7187]

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.

[@TheHypnotstCollector]

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 . )

[@sergiomedina7119]

Looks clean !

[@dougsweldingfabrication953]

Nice work.... Great fit !

[@robertpeters9438]

Glad to ser you using good straps.

[@donniceblakely1075]

Looks pretty good boss

[@jamesdegraff]

Don’t do any of this shit but love to know how things work. Love the channel.

[@randycordes464]

Great job on fixing that

[@billcarlson1730]

Nice job man!

Nice job, thank you.

[@davidholder3207]

A neat repair sir.

[@donnykiofetzis5775]

nice welding!

[@ypaulbrown]

Greg, late to the show, but always showing up sometime, cheers from Florida, Paul

[@duggandh]

Nice video, thanks.

[@bubbapate5740]

At least that shaft and a nice ring tone when you was chipping away at it.

[@jspice-kl2wc]

Thank you.

[@harveystephens6115]

Sometimes manual and simple is better! I thought it nice when you started with hammer and chisel!!!! Enjoy the channel!

[@SiboBushings]

Nice job, nice video

[@hubertrobinson8825]

That keyway looks factory made that's a job perfectly done my dad once told experience keeps the devil where he is

[@marctrossbach6560]

Hope you feel better soon

[@wmweekendwarrior1166]

Good stuff

[@michaelwatson4822]

Nice repair

[@rustyul]

You should have put it in the lathe. Grind marks on the end of the shaft don't look good.

[@scotthultin7769]

687 👍's up on fire welding thank you for sharing 😊

[@12Georgia83]

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

[@thomasheer825]

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.

[@user-di4bt7qu2i]

Great trick! Thanks for sharing!

[@Jamestreeman]

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.

[@a-fl-man640]

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.

[@vankatanemuedobre]

You have a very nice audio on your vids!

[@jblackops99]

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.

[@chuckmiller5763]

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.

[@iainkinsella4708]

Nice Work

[@MySynthDungeon]

Morning coffees on!! ;-)!!

[@GeneralSulla]

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! 😂

[@jamesriordan3494]

“Good enough for who it’s for” - if the customer chowdered it with the torch, no lathe work earned

[@rossnolan2883]

Brilliant 😊😊😊😊

[@victorjeffers1993]

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 !

[@AK2I47]

Always interesting

[@roryconiglione9486]

Well done

[@ypaulbrown]

the ArcCaptain seems to being working great........

[@bt9653]

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.

[@mikeschmidt7980]

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 .

[@OFW]

No, not a Union shop.

[@afish43]

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.

[@kenbouchet7874]

Nice Work. You show them how to use the jacking screws on the QD bushing!

[@OFW]

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.

[@danstiurca7963]

That's a bad day when you realize you torched the keyway.

[@afish43]

It usually came with 3 days off. So only the brave would volunteer to cut a bearing race or coupling half off a shaft.

[@user-fd4qx2yg9r]

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 😢

[@rbelang8331]

At 2:18, I felt an urge to start meditating... ;)

[@ericchisamore7168]

Nice repair! What filler metal did you use? Thanks

[@OFW]

Er70s6

[@cowthedestroyer]

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

[@davidfleishman2275]

Great thought on that shaft not been straight for the lathe.For sure a waste of tome to chuck it up in the lathe.

[@Hey_Its_That_Guy]

Nice repair, Greg! If that job required it, could you have used your Climax gear to machine that shaft end true?

[@OFW]

Technically yes, but I do not have the OD cutter yet for the climax.

[@larryburns4605]

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

[@lniner1]

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.

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!

[@jimsvideos7201]

Nice. Torch soot is good for giving accurate temperature readings using IR temp guns on shiny or curved surfaces.

[@hfdzl]

Also welding spatter will not stick to Acetylene soot
