Thumler Model A-R12

The Thumler Model A-R12 tumbler. This is a 12 pound rated machine, with a rubber barrel. You might expect it to be quieter than the Model B, but it is not. This is one of my multi purpose machines. I generally use it to finish larger stones (ones that are too big for a 3# drum and most of my stones are too big for a 3 pound barrel) and it is handy for testing new techniques. I made several movies while running with a plexiglass lid.
