The way to think about using tumblers is that they are simply
machines doing what you do by hand. First you have to smooth the
metal. By hand you would use files and sand paper. In a vibratory
tumbler, you use abrasive media. With gold I like to use at least
two separate batches - the first one being more aggressive, and the
second batch with a finer media. As in hand work, you need to clean
and rinse the work between batches.
Then to polish - manually, you would use a buff. With a rotary
tumbler, I suggest using stainless steel media for a short time,
about 45 minutes. Then for a high flawless shine, go back to the
vibratory tumbler and run for 24 to 48 hours in a dry media of wood
chips and pegs charged with simichrome or a rouge paste.
Stones are set after all mechanical processes.
