I’ll suggest that you purchase Judy Hoch’s book, “Tumble- Finishing
for Handmade Jewelry.” It explains the process very well and will
answer your questions… and others that have not yet occurred to
you. Rio carries it and the price is very reasonable.
Be sure to get stainless shot in several shapes. Those pointed
cylinders (Judy calls them “long pins”) work on tiny crevices and
details. I’ve had good results with a mixture of shapes. I use a
rotary tumbler and add a low-sudsing liquid soap. You can tumble
everything but set stones in steel shot. Yes, I tumble fabricated
pieces with bezels - not a problem.
Those little rotary tumblers are not very expensive. I have a couple
and each is dedicated to a different media. Just call me doing things
the easy way… or lazy!
Judy in Kansas, where triple digits are making things miserable
outside. So glad to have AC!
