I got the variable speed DC motor at Surplus Center, and provided a cheap rectified power supply, and sleeved the rollers with firehose from the same surplus center. One does need a 1/3 to 1/2 Hp motor to drive it. grind media was purchased at a ceramic surplus equipment Co. near Sacramento. Works a charm, Hank
