What should be a straight forward operation becomes, as always, a bit more complicated.

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.

Step 6: Clean the grinding dust :)

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.

@AerialPhotogGuy 4 ай бұрын

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! 🙂

@Preso58 4 ай бұрын

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......

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.

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!

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 .

We need to hold the jaws in the closing direction to compensate for the play.

I LOVE THIS KZfaq 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!

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.

@Rustinox 4 ай бұрын

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.

@Michel-Uphoff 4 ай бұрын

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.

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..
