Does anyone use those tumblers that you can buy from Rio Grande
to finish pieces?
What is it you're (your Boss) wanting to do with them?
Depending on the media (shot, grit, other) you can do different
things with them. They also come in 3 different types, barrel,
vibratory & magnetic. The vibratory & magnetic are faster than
the barrel type. They're usually used in the finishing steps of
castings or finished jewelry. They can also be used to tumble
I use a small vibratory tumbler with steel shot to finish fine
silver & sterling chain & other small pieces. The shot performs a
burnishing function on the items, they must be free from
scratches before put them in the tumbler. It's the easiest way I
know to polish chain!
Others can address tumbling with grit & other media as well as
'flow through tumbling'. Tumbling in one form or another, is used
throughout the metals (steel, iron, brass etc) & plastics
industries as a 'mass finishing' process.
