I read a lot of remarks about tumbling in the archives but I still
have a last question.
This is what I would like to do: After sanding, smoothing my pieces
(14k or 18k gold, maybe platinum) and giving them an intermediate
polishing step I would like to work harden them by tumbling them with
stainless steel shot in a rotating barrel. Do you think it is
necessary to give tumbled pieces a last polishing step to finish
them? Do I loose the hardening effect when I polish my pieces with a
very fine grit?
I will appreciate any comments, I really enjoy reading the posts on
