"I used an electric motor from a Beam central vac powerbrush. To control the speed I used a router speed control. Motor cost is about $30.00. Mounting is no problem but the speed control is necessary. Ken"
I asked for verification of the drill used on - Micro Drill or Mini Drill. He replied:
"HI Allen. RE: drill press motor. The motor fits the mini drill press and is an exact fit. Brackets can be made easily and the shaft is .250. It is a 120 v motor and once again this motor is fitted into the beater head of the Beam central vac. I use a router speed control to monitor the speed. I have more pictures. Thanks, Ken"
