Gday Gary, that is a very impressive result, you mentioned it was a credit to the manufacture but I’d say it’s a credit to you for how accurate the backplate was machined and fitted, beautiful job mate, that’s one bloody nice chuck, thanks for sharing, cheers
Wow Gary that is one nice chuck, it's hard to believe that it has been sitting around unused for half of a century. I like the two part video series. If you don't have a hour to spend it is a good way to break it up. Another thing is that it allows you to show the whole process on doing a proper job. Seems that I am always learning more from you, thanks for your time!
Harald, I figured it would be fairly accurate but quite surprised when I seen just how accurate it was. Always nice to have you stop by the channel. Gary
2 parts is great Gary, I watched them back to back this morning (Sunday) to be honest I can binge watch you all day buddy, wonderful work and presentation 👍
Doesn't get much more satisfying than watching that dial gauge barely move. Breaking these vids up or letting them run long doesn't much matter to me either way. Just cause you asked, Lol. Thanks for sharing. Stay safe.
I know guys like you take compliments begrudgingly, however your talent and machining intuition, is at a level which gives you a right to be a little boastful and smug, yet sir, you present your valuable content humbly and unassumingly, I salute your style. I find your content to be the most engaging of any utube machinist, it feels like a buddy showing you how to do stuff. Cheers and many thanks.
I am impressed, WOW Gary, that is amazing. It appears to be within 3 tenths. Always a pleasure to watch you work. Says a lot for the lathe as well. The care and attention to detail is a pleasure to watch. I wish I had a 6 jaw on my lathe but I doubt it is worthy of it. Maybe someday I will have my bucket list Monarch 10EE. Thanks very much for sharing Gary.
I love the trolley. It seems the older guys are masters at designing and fabricating the best jigs.,,,,,....must be why we call them master machinists.
Watched both parts, One then two. a lot of good information and techniques. I appreciate that you took the time to do it "right". Like when you took off the little Cushman logo disk. A lot of people would pry it off and ruin it, or not take it off at all. And of course using new drive rivets when you put it back on. The concentricity when completed was very impressive. That much weight spinning around would scare the hell out of me.
Jim, I appreciate you watching and leaving a comment. It’s funny how you can get used to the big chucks. They always seem big at first until you use them for a while. Gary
Wow Gary. That chuck is a beast. As to the split videos - split or not split, all the same to me, I'm going to watch whatever you share. I don't mind longer videos. Thanks for sharing.
Impossibly Accurate ! ...... must be a faulty gauge (LOL) ! I know on some of my scroll chucks with 3 tightening positions, that going around and tightening each of them while indicating the workpiece ( similar to independent chucks) I can improve the accuracy somewhat . Not sure the physics behind that, but it has kept me from throwing a chuck, that I had thought worthless, into the scrap pile . Are we going to see Gary making a new chuck key for that beauty sometime in the future ? ........ or you gonna stick with the breaker bar . Great set of videos ...... and yes, I vote for the two-part ones ! Great job as usual .... you the Man !
I was just getting used to the breaker bar LOL And it’s amazing how you can tweak an indicator to behave the way you want it to behave LOL I have found in the past that when you get different results depending on where you put the chuck key tells you that you have a little extra play where the scroll fits into the chuck. The scroll will always wanna push away from where you put the chuck key. I hope that makes sense. I appreciate you watching the video and leaving a comment. Gary
Hi, it looks like you are a very talented, I have only just found your territorial on other machinery restoring is I’ve just been watching the one that where are you made of thread adapter for a Watkin RU , This is a serious bit of kit and I think without perform most modern lathes today. I have a Wadkin R8 which I restored back in the mid 90s I’ve just left a comment on territorial that you done. Stay safe keep up the good work look forward to seeing some more of your work. Phil from the moulin France
Hi Gary, take my hat off to Cushman, certainly a masterpiece of machining. We had the same Lathe in our shop in the refinery, operator accidently tore off the taper turning attachment whilst removing a flange from the chuck using the gantry crane, didn't see the chain wrapped around it!
More like big ASS chuck than big AZZ! Great find, it's hardly done any work! I like your ingenious system for mounting it - yes it's over 300lbs quite a lump!
I think you should break up your long videos into 12 to 23 parts!!......yea that's it! Lol Great job on the chuck, looks awesome! 2 parts works for me 👍
Don't you have a ring to secure the chuck for lefthand threading? This chuck is a gem. So accurate and in splendid condition after your restoration. What a great find. Your work is perfect, thanks for sharing.
Frank, with an L Series long taper they use a key in the spindle shaft to lock the hub so running it in both directions is no problem. They use a large nut that threads on to the hub in tightens up the taper. Hope that makes sense. Gary
The scrapyard I bought the chuck from buys out a lot of companies. I’m sure the company had it sitting on the back shelf for many years. I’m glad I got it before it spent too much time out in the weather.
My smaller lathe is a gunsmithing Sheldon with two 5-in original Cushman chucks. I knew that Cushman had a great reputation, but these old chicks seemed strangely constructed. Surprisingly small screws through the face, just a handful of odd choices. They have very little run out, but the guy I bought it from also sold me his tool post grinder so I don't know if and how many times the Jaws have been ground though they are still quite sharp. Does the reputation hold for their especially small chucks? They both seem slightly undersized to me, there's an 11-in swing. I've been planning on replacing them with an 8-in six jaw but my budget would require an import. Do you think the 5-in chucks are worth putting in the work to rebuild them? They are both really pretty tight and show no signs of ever being crashed.
They are strictly for show. LOL To be honest, I do more natural gas compressor Valves than anything and they just require light cuts. And the wall stays cleaner because I do not like using oil on the Lathe, to me it’s way too messy. I appreciate you checking out the video, thank you. Gary
Amazing quality and quality of materials used back then. So your demonstration of the sensitivity of the indicator begs the question about deflection when in use. If you have a piece projecting 12” or so from the mouth of the chuck, under load from the tool post, you must see an incredible amount of deflection during the cut. What’s your take on that and how it affects accuracy of the workpiece?
Eric, when I was showing the indicator moving while I was pushing on it, what I was doing was pushing on the indicator base. I was not pushing on the work itself. Of course anytime you clamp up a piece of material that hangs out you’re going to get deflection that’s why you use the tailstock to support the other end. But with the wrist pin that I had mounted in that chuck I don’t think I could’ve pushed it hard enough to get the gauge to move. I hope that makes sense. Gary
Gary you find the best stuff and that chuck is now like brand new , great job as always . I want to ask you if you prefer a thread on type chuck or the cam lock type and why . I'm looking to buy another lathe and would like your opinion . thank you for the videos , and I think splitting longer videos into two parts is a good idea , but to me it doesn't matter .
Otto, I have a few Lathes and I have L Series long taper and D1 . Which ones do I prefer, that is a good question. This is only my opinion, and some may have different opinions. But I like the positive lock up of the L series long taper. But with that being said there are times where it is more difficult swapping chucks than it is with my D1-6 mounts. The D1 mount is an awesome mount and in my opinion much easier when swapping chucks. I hope that helps. Gary
I understand that in your case it was irrelevant, but this set through the chuck feature seems to add quite a bit to the price tag. I'm very much a novice so forgive me if this question is ridiculous, but from how I understand the set through systems, it does not seem like something that would be terribly difficult to add to a chuck's backing plates. It seems like the backing plate might need to have a slightly longer neck, and tapping the three holes at 120°, seems pretty doable. The rub as I see it comes in with mating a surface to a tapered round nose like an L-1. That sure seems daunting, but investing in the right grinding wheel and using a softer brass seems significantly more difficult, but still doable. Have you heard of anybody attempting a DIY set through adaptation? What am I missing or underestimating that makes doing this so difficult? I'm sort of surprised there are not companies selling aftermarket set through backing plates for consumers desperate for an option besides replacing their chuck or regrinding the Jaws. Or are there? Please don't take any of these questions as a critique of the methods you chose. I always learn quite a bit from your channel and the finishes you get out of Rusty mistreated equipment kind of blows away all of these evaporust based channels. If I take the time to take something apart and clean the whole thing, I don't want something shiny nearly as much as I want massively improved performance. And shiny. Thanks as always for your videos. I really feel like I learn the right way to redo things.
Tom, It’s always hard for me to decide how to do a video. I personally don’t care for long videos but I think it’s because I don’t have much free time. But I get comments from a lot of people that want to see more. I know at the end it’s impossible to please everybody. Always nice to have you stop by. Gary
I don't consider anything under an hour "long" Also I DO NOT watch the "short" garbage that TH-cam has been encouraging lately, partly because they force the "phone" vertical format, but mostly because it's a waste of time. Thirty of 'em aren't worth one of your halves.
Thanks for posting both parts together. I don't mind them being split at all. Thanks for your time and effiort put into making these videos
The only thing better than a old iron machine works is two old iron machine works video's, great video Gary, keep'um coming..
Gday Gary, that is a very impressive result, you mentioned it was a credit to the manufacture but I’d say it’s a credit to you for how accurate the backplate was machined and fitted, beautiful job mate, that’s one bloody nice chuck, thanks for sharing, cheers
Thank you Matty, I really appreciate the kind words. Gary
I've worked with some great machinists in my day and ive said before and I'll say it again. You good Sir are amazing at your craft.
Randall, I really appreciate the kind words. Thanks for checking it out. Gary

Thank you Andy
Makes you wonder how many "got away", thankfully Gary you rescued this one, great work old boy.
Real Hollywood job!!! Ready now for decades of reliable service, thanks to your careful attention to detail.
I wish my little 3 jaw chuck would be that accurate. That is one nice chuck.
Harald, I figured it would be fairly accurate but quite surprised when I seen just how accurate it was. Always nice to have you stop by the channel. Gary
2 parts is great Gary, I watched them back to back this morning (Sunday) to be honest I can binge watch you all day buddy, wonderful work and presentation 👍
Thank you Ralfy, you always have such kind words. Sorry I’m hit and miss on keeping up with your videos, I have just been crazy busy. Gary
😳 NEVER seen a 'standard' lathe chuck that accurate before!!!!! 😃
.001” or less anytime on a single chuck is awesome 🤩
Brian, It was definitely a pleasant surprise when I finally got to run it.
I always appreciate when you take the time to check out my videos. Gary
Very nice restoration, Gary. Thanks for taking us along.
Thank you Joe, I appreciate you taking the time to watch. Gary
I'm sure that a LOT of machinist's out there have cracked jaws from dropping them so hard at that accuracy! Amazing.
Beautiful chuck, like new and super accurate, heck of a find. Enjoyed, cheers!
1&2…great video production/discussion/demonstration….enjoyed and very nice restoration
Thank you Chuck.
Split was no problem whatsoever. Thanks for posting!!
That accuracy for that size of a chuck is amazing! What a marvelous job you did on the restoration of that beautiful tool. Thanks for taking us along.
Thank you Bruce
Hello Gary,
The obvious quality of the Cushman chuck and your skills is a fabulous combination... See you on the next one...
Take care.
Paul,,
Thanks Paul, I appreciate it. Gary
I always love these repair and resto videos. Splitting the video is fine with me. I just piggy backed to part 2. Thanks for sharing.
Thank you Terry
Doesn't get much more satisfying than watching that dial gauge barely move. Breaking these vids up or letting them run long doesn't much matter to me either way. Just cause you asked, Lol. Thanks for sharing. Stay safe.
Wow. So that's how the bug boys do it. Makes me want to look at my little Prazi the next time I have a job to do.
2 Parts. Glad to get the detail, trying to learn here, need the instruction. Thanks for posting
Thanks Gary. What ever is convenient for you , works for me.....cheers
Thank you Gary! Really like your videos and look forward to the next ones!
thanks for sharing your diamond in the rust!
What an awesome chuck. And an awesome job of getting it running true. Love LeBlond lathes! Thanks for your time and effort!!
Thank you Danny

Rupert, I think this is one of the nicest comment I’ve ever got. I appreciate the kind words. Gary
I like the detailed look at the process, if takes two or more parts bring them on! cheers!
Thanks Steve
Two part videos are A OK, thanks for the interesting material.
Being that accurate is ridiculous. Beautiful chuck great find.
I am impressed, WOW Gary, that is amazing. It appears to be within 3 tenths. Always a pleasure to watch you work. Says a lot for the lathe as well.

Thank you Greg, anything that makes handling heavy stuff easier is always a win. Gary
I'M BLOWN AWAY.
Wonderful
nice video of how to refurbish a chuck. I too am amazed that a non-set tru chuck will be that close Good "barn find"
Watched both parts, One then two. a lot of good information and techniques. I appreciate that you took the time to do it "right". Like when you took off the little Cushman logo disk. A lot of people would pry it off and ruin it, or not take it off at all. And of course using new drive rivets when you put it back on. The concentricity when completed was very impressive.

You get used to it the chuck on my big Monarch is over 1000lbs! At 750rpm right next to you it is very attention getting. 😂
Jim, I appreciate you watching and leaving a comment. It’s funny how you can get used to the big chucks. They always seem big at first until you use them for a while. Gary
very good job
Wow Gary. That chuck is a beast. As to the split videos - split or not split, all the same to me, I'm going to watch whatever you share. I don't mind longer videos. Thanks for sharing.
Thank you Alan
Nice work👍🏻 enjoying the channel, keep the videos coming.
Dam that is a great find, nice work
Gary, great work. Worth all of the $20 you paid for it😉 👍🏴
Two parts is fine Gary. we can spread out the fun! Edit: A few tenths? That's fun!
Nice work. Thanks for sharing 👍
Great job 👍
Zero complaints about long weekend watch material lol
Very nice! Wow, even!
Great video, down right interesting

GREAT SERIES !!!
Having two parts is just fine.
There good for another100 years!
That's one sweet chuck.
Nice video!
Hi Gary, take my hat off to Cushman, certainly a masterpiece of machining.
We had the same Lathe in our shop in the refinery, operator accidently tore off the taper turning attachment whilst removing a flange from the chuck using the gantry crane, didn't see the chain wrapped around it!
Willem, ripping off the taper attachment accidentally would definitely ruin somebody’s day.
Thanks for watching. Gary
Man, that turned out nice 👍
a few tenths in the gears, bearings, main shaft and chuck... i guess it will work!
amazing what you can feel with your fingers after stoning very nice work.
Thanks Mark
Great find! Nice work!
nice.. id like to find a big chuck lathe someday. you did good on the chuck 👌👍
Thank you Doug
Great work. The accuracy makes up for all the work. Just noticed you have no backsplash/chipguard on that monster.
John, no backsplash. Just some high tech wall texture and paint LOL.
Thanks for stopping by. Gary
two parts i like
More like big ASS chuck than big AZZ! Great find, it's hardly done any work! I like your ingenious system for mounting it - yes it's over 300lbs quite a lump!
She's a beauty!
Two parts is fine.
Two part videos are fine. Have you thought about making a adjusting plate for the that chuck
No, not for this chuck.
One part, two parts--whatever it takes is fine with me.
I think you should break up your long videos into 12 to 23 parts!!......yea that's it! Lol Great job on the chuck, looks awesome! 2 parts works for me 👍

Crazy they didn't just sell the chuck instead of letting it rust away. Takes up a bunch of space also.

that’s a masterful restoration. The chuck is a showpiece. Can you keep it from rusting?
Thank you, and yes it should be easy to keep it from re-rusting. I appreciate you stopping by. Gary

You sure do pay attention to every little detail
2 part videos were Fine.
Two part videos should work well with some of the repair work you do as it takes multiple steps to put a unit back into service. AL B.
😁😇😁
Split video’s are fine with me.
Came out awesome. I think shorter videos are better for viewers attention.
Tom, It’s always hard for me to decide how to do a video. I personally don’t care for long videos but I think it’s because I don’t have much free time.

Enjoyed the 2 part series, for my 2cents. As far as the work, all I can say is "BEAUTIFUL" ! Thanks for your time and education.
Thank you John, I appreciate that. Gary
