I managed to pick up a lightly rusted, never used, 6 jaw, Adj-Tru, Buck Chuck with non reversible jaws. I cannot buy a factory ready back plate for the chuck since the mounting I need is 1 1/2 x 8TPI, they don't make those. So I ordered a pre-tapped blank Iron back plate.
I know how my non adjusting back plate fits in my current 3 jaw chuck, super tight. What would be the spacing needed between the shoulder and the plate for this adjust true chuck?
The new chuck is 6" and has 3 mounting holes, it came without the cap head mounting screws. Does anyone know the screw size, or how much play should be in the screw slot?
Any help or support machining the back plate would be appreciated.
