Hello Michel. Fabulous result all down to your intelligent problem solving. Having problems to solve is what keeps this hobby interesting. Here’s to the next problem. 👏👏👍😀
Good job Rusti. Well done. What is happening on YT today, I have just watched Paul threading a potato, and now you have a plate with cutlery on your machine 😀😀.
Thanks Michel. I have to do the same on my big chuck because the jaws are bell mouthed. I bought an 8mm carbide drill bit hoping it could drill all three jaws for dowel pins. Your 3 plate method looks simpler. But, I have a drill bit......
Nice work Michel. I did the same on my lathe years ago. The bar would run slightly off axis so I ground the jaws. It now seems “ happier” if I wrap the bar with a strip of .010” or.25 mm paper for repetitive results. Very enjoyable video as I am on a vacation from my shop and the snow, enjoying the Florida sunshine for a couple of weeks. Enjoyed your video and the break you provide every week. Stay healthy and enjoy your life my friend, adieu!
Your homemade "tool post grinder" is friggin brilliant. I've thought about doing something similar with my little die grinder. Your setup looks rock solid rigid too.
Hi Michel ☺ your inventiveness never ceases to amaze me, you got a good result, accurate for government work anyway, lol. And I'm sure further modifications will keep your interest going. Thanks for another interesting video mate, enjoy your wkend, best wishe's to you and your's, Stuart UK.
That is almost exactly how I set mine up, except I use thicker blocks so I can put the pressure at the tips of the jaws instead of at the face of the chuck. I want the pressure at the tips so it doesn't have a taper to them (some people refer to it as "Bellmouth"). Well done! 🙂
Good result there Michel. For your issue, could you have bored a hole in a piece of steel then opened the outside jaws into that hole? Then you would have plenty of room for your grinding stone to clean up the inner jaws, and nothing will be in the way of the grinding stone.
Winner, winner, Chicken dinner, for that plate you had on the lathe 😁. Nice result. I am considering casting a holder for my Die Grinder so I can grind with it on the lathe. 👍
I did the same although I used aluminum between the jaws and used the boring bar to cut the jaws. You got better results but I don't think the grinder had anything to do with it. My chuck was completely worn. The boring bar worked very well.
Good job Michel. That's ten times (or more lol) better than before. Under one thou is bloody impressive ! Everything working without a hitch first time? Nah never in my lifetime!
Dear Michel, Thank you for making this video. I loved the plate gag! I know that eating chips is bad for the health but this?! However more seriously, I have read in the model engineering press several descriptions of grinding chuck jaws. The problem is always trying to hold the jaws whilst under pressure from the scroll within the chuck but also leaving access to the jaws. I have never previously seen such an effective method described. I have to set up an old lathe of my own: a Pools Special and in the likely event that the jaws are out of true I shall definitely use your method. Simplicity is genius. Thank you for sharing this.
Hi Michel, that is an amazing improvement, well done!!. If you need it any better then looks like the spindle would need attention first. I expect there are lots of videos showing how to do this, the one I watched was done by Mr Crispin. Your outros always make me laugh!! Have a great weekend!!
I LOVE THIS RUclips CHANNEL!!! Please do not regard me as an internet safety nazi for sharing my story: In the early 19and70s I was a long-haired auto mechanic in a small shop along with a number of other young long hairs. One day one of them was tuning the carbs on an Austin-Healey Sprite, when suddenly a long bit of his hair got caught up in the fan belt. He made a GREAT noise and I looked up from my work to see a white circle, about the size of a US silver dollar, in the side of his head. In a short period of time, that white circle started turning pink, then red and finally it was bleeding. He began wearing a very short crew-cut hair style after his mis-adventure. I chose to begin tying my hair back and tucking it down inside the back of my shirt ... a practice I still follow if I am wearing long hair, as is my wont, all these many years hence. Please do be well ... and careful my fellow long-hair!
Love the humor 👍. What would happen if you took a scrap of sheet a few mm thick , bore a hole on the lathe, big enough to later spread the jaws in the hole keeping them under tension .
Step 1: Make tool post grinder out of what is in the pile. Step 2: Make up clamping system for 3 jaws without pins. Step 3: Make trial cut and move clamping blocks. Step 4: Do final grind and make the chuck more accurate than it was from the factory from whence it came. Step 5: Do a happy dance and go have a beer 😁 As always, nicely done.
i have several sizes of pipe cut off in thin slices and tightened them out to the inside of the rings. I turn the chuck by hand in neutral, back and forth and then on to the next jaw. I got mine to .0025 in both sides of of my reversible jaws
Good mix of solutions Rusty, preloading the chuck jaws evenly is tougher than it looks. nice work. My wife draws the line when it comes to bringing the fine china out to the workshop 😂😂
Information you could take an big ball bearing ring to clamp the chuck open and round. Ballbearing rings are almost perfectly round. I wouldnt trust 3 soft steel pieces i clamp on.
@@fearlyenrageI thought you meant holding the ring by opening the chuck. Robin made a groove in his chuck jaws to be able to hold on the ring while tightening. That's brilliant.
Take a look at the fixture that Don from the RUclips channel "Don Dyar Machining" built, it is simple and quite safe compared to other jaw grinding fixtures and can be used whenever needed as a tool. You can see it in action in the video "Advanced lathe chuck fitting part 2 the grind".
Kurtis at CEE drilled holes in his chuck jaws using a carbide end mill, so that he could thread them for attaching soft copper pads. I'm going to try it when my new to me lathe is finally running.
Thank you for this video, I was wondering how to do this on my machine without special grinding tools. When you say you 3 "one hundreths" of runout, is that one hundredth of a mm?
great stuff as always... how did you true or align the center axis of the drill and stone to the chuck?, insuring they are set up perp/ or at 90.............. does it even matter ? ..
Before grinding the jaws should the bed be leveled first? I have a MX210V lathe that the headstock is horizontal misaligned by .020" over 6" when the bed is leveled. My headstock is not adjustable.
Hé naamgenoot, goed gedaan! Je zou nog even de runout kunnen controleren bij assen met andere diameters. Natuurlijk kan slijtage van de klauwen de oorzaak van de oorspronkelijke runout zijn, maar het kan ook een oneven slijtage in de spiraalgroef zijn, en dan heb je bij een andere diameter toch weer runout. Die is dan niet te verhelpen met eenvoudige middelen.
Lovely video once again. Though you showed 1 jaw being grinded, is it silly question to ask about remaining ones?was worth the effort to grind the jaw reading you mentioned showed great improvement. My lathe is down for electrical problem which will be dealt wih tomorrow. Thanks for great video may there be many more😎🙂
To make sure the 3 jaws are concentric, they need to be done in one setup and grind them at the same time. So, that's what I did. Maybe it was a bit confusing that I showed only one jaw in my hand.
@Rustinox sure, fully understand. I'm from Poland and they are totally not typical here. Will need to change whole chuck probably... Thanks for the videos, I really like them.
sinse you have another lathe - why not do a ring to go on the outside of the jaws? thightening outwards - or is that pherhaps a stupid idea due to the coiled thread inside the chuck,that most likley has a couple of hundreds of play,and differs slightly from otwards thightening and inwards thightening..
If you would have had the lathe running MUCH slower it would have worked the first time. You want the chuck to go about 50 rpms and the stone spinning as fast as you can. (At least 2500 rpm)

I would call that a win too. 👍
Indeed. Thanks Tom.
Hello Michel. Fabulous result all down to your intelligent problem solving. Having problems to solve is what keeps this hobby interesting. Here’s to the next problem. 👏👏👍😀
You're right. Thanks.
A simple project can quickly escalate into a headache. You identified and recovered from the problem very well. Nice work!
Thanks.
Great one. I had to watch it this evening - did not want to wait until the morning. Simple rig, great result. It's a job I need to do sometime. Cheers
Simple and effective.
@haxbyshed your potato threading was 😂
Excellent innovative idea on 3 jaw spacers to allow grinding, very clever Michel 👏.
Always a school day Sir.
Thanks for sharing.
Don't know if it's innovating but it works :)
Good job Rusti. Well done. What is happening on YT today, I have just watched Paul threading a potato, and now you have a plate with cutlery on your machine 😀😀.
I had the same thought 😂
It's getting crazy 😁😁
Why not? :)
Nice prop, the be World needs more sense of humor, less stress and wars 👍👍😁
And two pancakes on the plate would have topped it off 👍👍
Nice job Michel. I gotta do the exact same thing to my 10 inch 3 jaw.
Go for it, Randy.
Michel with this type of hobby, the blue bird of happiness is always circling from my experience. Good onya
Lol. Thanks.
Considering I rarely get to do ANYTHING without any farting around, I think that was a challenge accepted and well met. Always entertaining.
Lol. Thanks.
Absolutely great. Trying different possibilities until it "works", as you like to say.
Congrats !😊
That's the spirit.

A job done in half the time is half the fun .
You'e right.

I want the pressure at the tips so it doesn't have a taper to them (some people refer to it as "Bellmouth").

It works great.
Good result there Michel. For your issue, could you have bored a hole in a piece of steel then opened the outside jaws into that hole? Then you would have plenty of room for your grinding stone to clean up the inner jaws, and nothing will be in the way of the grinding stone.
We need to hold the jaws in the closing direction to compensate for the play.

That did work out perfectly in the end. A nice simple toolpost grinder Michel. Cheers Nobby
Thanks Nobby.
What a great old lathe Michel. Nice work on the Jaws.
Steve.
It's indeed a nice machine.
I hadn't seen the technique of using those little tabs between the jaws. I will have to do the same when I get to this project on my lathe chucks.
Simple and effective. That's how we like it.
Hi Michel, that is an amazing improvement, well done!!.
If you need it any better then looks like the spindle would need attention first. I expect there are lots of videos showing how to do this, the one I watched was done by Mr Crispin.
Your outros always make me laugh!! Have a great weekend!!
Indeed. The spindle is on the "to do" list.
Thank you Michel and have a nice weekend.
Thanks.
From now on no setbacks nor the need to make fixtures! Good result. I am emboldened to true up my chuck jaws. Thanks Michel.
Go for it. It makes a big differance.

Thanks.
Great job Rusti. I am going to do mine now. Thanks for the video.
Go for it.
Problum solving is the second best part of your show.
Your humor is the true star.
A simple ring to open against?
Could hold jaws in place?
Thanks.
Thanks Michel 👍 🇬🇧

so the ballbearing idea from RRenzetti will only work on not clamping into the middle?

Can’t argue with success!👍🏻👍🏻👍🏻
Thanks.
Nice job with outstanding results!
Thanks.
Nice to see you are going to the milling machine first.
The Shaper is having a rest.😮
This part was easier on the milling machine.
Hi! You 're best!!! ))) For drilling hardened steel You can reshape bits for concrete. It's work. I tested it.
Indeed, it works very well. But not in these jaws.
Weer een prachtige video met duidelijke uitleg!!! Bedankt!
Dankjewel.
Good Job Michel! Now you won't be making bananas!!!!
Indeed.
Thanks

As Sammie always said,,,, Get it Done" and you got it Done 👍👍.
Yep. Thanks.
Thank you for this video, I was wondering how to do this on my machine without special grinding tools.
When you say you 3 "one hundreths" of runout, is that one hundredth of a mm?
Yep, I'm metric.
great stuff as always... how did you true or align the center axis of the drill and stone to the chuck?, insuring they are set up perp/ or at 90.............. does it even matter ? ..
I see that if it's only working the corner of the stone it's radius remains equal.. great stuff. thanks for all your insight.
The movevent of the saddle is the aligement. But I suppose you already figured that out :)
Good one !!
Thanks.
Hi . Nice job with good descriptions.
I've a question: why you didn't use a ring shape piece on the outer edges of the jaws to preload them.?
We need to tighten the jaws outwarts, as if there is a workpiece. The ring would push the jaws inwarts.
Thanks
Yeah that is all right
Well done!
You're a true vizard...... Taking the chuck off to get the distances in place.... Like the Colombi Eggs?
Just a bit more work to make things easier.
Before grinding the jaws should the bed be leveled first? I have a MX210V lathe that the headstock is horizontal misaligned by .020" over 6" when the bed is leveled. My headstock is not adjustable.
I don't think it matters much over this short distance.
Hé naamgenoot, goed gedaan!

I'm glad that you didn't try improving on the run-out and end up making it worse as someone else I know might have.
Making it worse would't be a real progress :)
Brilliant. Too easy, if only.
It works.
If there are no problems, you are overlooking something! Don't forget to take the chuck apart to clean out the grit.
You're right. Will do.
Did you clean out the scroll and jaws to be sure it is tightening even before you ground it? I didn't and now need to find replacement jaws.😂
Yep, all clean before grinding. And clean again after grinding.
Why drill holes when you could just clamp the ring using the steps in the jaws?
We need to hold the jaws in the closing direction to compensate for the play.
Is this a RöHM 250 chuck? If so, maybe you have some spare outside jaws to sell because I have a real problem to get them. 😊
The jaws you see in the video are the only ones I have. So, I suppose you understand I don't want to sell them.
@Rustinox sure, fully understand. I'm from Poland and they are totally not typical here. Will need to change whole chuck probably... Thanks for the videos, I really like them.
ROBRENZ did a very detailed video on grinding chuck jaws and why he did it the way he did. I would recommend it to anybody undertaking this task.
I will check it out.
sinse you have another lathe - why not do a ring to go on the outside of the jaws? thightening outwards - or is that pherhaps a stupid idea due to the coiled thread inside the chuck,that most likley has a couple of hundreds of play,and differs slightly from otwards thightening and inwards thightening..
We need to hold the jaws in the closing direction to compencate for the play.
Deserved its own custom toolpost holder. You could have kept, and also added more rigidity.
No need, I don't use it often.
@@Rustinox would you use that logic with a parachute?
👍😎
Thanks.
If things were always easy how boring that would be. Every challenge is a learning opportunity.
Absolutely.
And "too easy" would be boring! :) :) :)
You're right.
If you would have had the lathe running MUCH slower it would have worked the first time. You want the chuck to go about 50 rpms and the stone spinning as fast as you can. (At least 2500 rpm)
Could be. Who knows? :)
Why don't you just make a block three-way like that
I'm not sure I understand your question.
Too easy 😂
The inspiration needed to grind my lathe jaws👍
Go for it.
Everything working first time ? ...
Too Boring.
God job.
Well done.
Thanks.
I am Indian sir I am working sir lathe operator
That's nice.
You just make it look "too Easy" ! Nice work Rusti. Always enjoy.
Well, it is easy. If it works :)
