And with more jaws, more surface touching the work. Less pressure
and the same holding power. Chuck soft materials and have plenty
of holding power.

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?
