Among various stuff that followed me, there was this six jaw chuck:

this is a plain back chuck, and I wonder if it makes sense to keep it
and adapt to my Clausing lathe. I can buy plain back mounting adaptors
for my lathe easily. I did it once when I had to machine it to fit the
four jaw chuck. This machining actualy improves lathe accuracy.

The question is, do I really need the six jaw chuck.

When was the last time that you had to use it, and for what reason?

It appears that that chuck was crashed, based on the gouges in the jaws.
Before I spent much time figuring if I could used it, I'd check that it
was still useable.
