Greetings, I’ve just begun my first foray into tumbling as a
polishing/burnishing step. I’ve read with interest the debate on
vibratory vs. rotary tumblers – for now, I have a small rotary
tumbler and I’m using mixed steel shot with Vital TM-121 polishing
powder compound and water. This is for sterling, by the way.
My question is this –
How do you know how long to let it tumble? Do you stop it
periodically and check it? Any general guidelines?
I’ve read about using clean sawdust to dry your pieces when
they’re done. I don’t have any sawmills around to get an easy
supply of the stuff. My husband pointed out to me that if the goal
is complete drying, uncooked rice might work just as well, as it’s
even more of a dessicant than sawdust. Has anyone tried this? How
about the wood chips you get (i believe they’re aspen?) for lining
Do you dry your shot in the sawdust as well? If so, how do you
get it all out of the sawdust and clean again without getting
sawdust into your next round of polishing?
