another surplus gear motor.

The Lloyd Sponenburgh ball mill design works great as a tumbler, and
you
don't need a gear motor:

Similar, but my version is a bit beefier: http://wpnet.us/tumbler.jpg

With water and media, the tank weighs ~45-50#.


Please, Pete. Don't confuse that design (which was based on mine) with
mine, exactly.

My mill design will handle two jars ("tanks") of over 50lb each.

It can't be based on yours, since I built it nearly a year before ever
seeing your design
