This is one of the tumblers I use.

I got the idea from Barb, the owner of a hardware company in New England.

She told about having set up a whole wall of these running off one motor.

Each pail can have a different grit polish in it.
parts can be loaded into a pail of grit and placed into the tumbler mechanism
then removed and dumped onto a screen to sift out the parts and polish.

The polish goes back in the pail for the next batch,
the parts are cleansed and loaded into the next finer polish pail,
and that pail is loaded into the mechanism.

Works great. though I need to make a better lifter than just the 2x2 on the side, that puts too much stress on a single spot on the plastic pail.
It needs to be wider at the base where it sits on the plastic pail side.

The mechanism is a commercial paint stirrer I picked up at an auction of an old hardware store.
I just drilled another hole in the angle adjustment to make the pail more horizontal so that parts could tumble.

 Here are some tumbled parts.

Tumbled tools: Repoussé tools tumbled clean after hardening. They were tumbled in a sawdust/course hand rubbing compound mixture. (available at your local auto parts/paint store) This removes all the caked black oxides and cooked on corn oil from quench.
