This large heavy duty pulley wheel accepts standard V-belts and can be used to provide power to the Wonder Junior Deluxe mill from a variety of power sources. Whatever power source you may use, the Wonder Junior needs to be turned no faster than 300 RPM (revolutions per minute), which is about twice the typical speed of hand cranking. Power sources are limited only by your imagination. One popular approach is adapting a standard or exercise bike so you can use leg power rather than arm power. An electric motor can be used, but note that motorizing the mill voids the manufacturer's warranty. (Use of the manufacturer's separate Power Drill Adapter accessory does not void the warranty.) The Pulley Wheel includes a special tool that makes handle removal easy. If you motorize your mill, a full belt guard is essential to prevent injury.
