ball mills
Our pyro plans out compete our production rate. I know mine did. Plenty of people use the Thumblers Model B. If you can find a high speed version, even better. They run at about the right RPM as is, so you don't need to modify them. Another similar mill is the Rebel 17, which is supposed to be a heavy duty version of the Model B.
