Lathe: Gripping ID instead of OD ? dragonbreed@comcast.net 05-01-2008

Hello. Looking for a round device that one end can acccurately grip
(via expanding fingers?) a 1/2" round ID of a steel "puck", so the
whole outer surface of the puck can be sanded/polished. The other end
I can chuck into a lathe. Is there anything off-the-shelf available ?

Thank you.
Marcel

Dio you have a lathe? If so, make a tapered mandrel to slide the part
on to.
