Hey folks,
I have been messing around this chuck for like 2 hours without getting even close to be dialed in at all.
I ordered it from Chris Hightower his 3 jaw chuck to install on the back of the spindle of my metal lathe.

It has 2 sets of screws on the sleeve (small screws and the big screws that are closer to the TAIG chuck).

I am not sure if anybody has the same setup from Chris and what was their approach on getting this dialed in.

Even if I do this on my own I know that one way or another I will get this right but a few nice hints or ideas would be nice.

This setup is not threaded.

Are you talking about Zeroing it!!

If you are trying to Zero the chuck, take a dead Center and put it in the chuck, then just tighten the screws that hold the chuck in place so that if you lightly tap it with a RUBBER maillot you will get small movements.

Next put a dial indicator on the dead center and zero it, then turn the lath on slow and look for the high point and lightly tap the chuck with the Maillot. Stop the lath re-zero your dial indicator and check it again, repeat until the chuck is within one thousand run out or less, I would continue until completely Zero.

Hope this is what you are looking for.

Tapping is not the solution for this type of set up. Put a ground steel dowel rod or dead center in the chuck as was mentioned. Rig your dial indicator up to touch the rod. Use the large screws to zero it in. It should take less than ten minutes to set up. Once set then just snug the other screws up for additional support.

Thanks Chris. I will try that. I was using both big and small screws and that multiplies by a lot the chance of errors and patience

Is this just for the rear chuck?
 
Tony if that's got that tiny little chuck with aluminum jaws , you need to Bor them if thats the case call me I will walk you through it . When you get serious this is the chuck on my main lathe and I lap the jaws every six months to keep them super true. the chuck it self costs half of that little lathe does.

Where did you get that backplate???

It doesn't look like a Bison..

I have a 6 jaw PB laying around and I'm wondering if I can avoid spending the 300.00 they want for one...

Here is a picture of the chuck threaded and mounted on the lathe.
My runout? 0.001" ;)

One more picture.
The picture was taken without the gear cover. The lathe has the gear cover with that chuck mounted.
