I'd like to get some soft jaws for the 3-jaw chuck on the Clausing 5914
lathe. This appears to be the chuck that came with the lathe. The jaws
are two-piece, and can be removed and installed the other way.

The chuck body is marked "BP71/6206", and is 8" in diameter.

Apparently these jaws are the "American standard tongue-and-groove"
type. The lengthwise groove is 0.31" wide, the crosswise tongue is
0.501 wide, and the centers of the screw holes are 1.75" apart.

There seem to be a lot of people making chuck jaws, none of whichg I
know anything about.

What sources/makes are good, are bad, and why?

Thanks,

Joe Gwinn


They're easy to make if you have a mill, Joe. I've never purchased soft
jaws in my life! The best choice is mild steel, so the jaw can be rebuilt
by adding new metal after they're served a long and useful life. I have
also used both 7075-T6 and 6061-T6 aluminum.
