Customer Testimony

"What is the Power Pro? Simply put, this is a headstock powered with a DVR, digital variable reluctance motor, whose performance goes beyond that of DC and AC variable frequency motors."

"While the old Shopsmith headstock achieved a useful 7 to 1 speed variation, using variable pitch pulleys, the DVR powered Power Pro has a 40 to 1 speed range, 250 to 10,000 rpm, providing full torque throughout. The computer/controller also has a mode that can assist in selecting the proper speed for a particular operation. The computer senses the load, and automatically provides the necessary torque. The smooth and quiet operation is impressive. Placing a cup of coffee on the table reveals nary a ripple, even at 10,000 rpm."

"Rated at 2 HP on 240 volt, users will find that the Power Pro’s ability to sense torque makes it possible to do table saw ripping equal to many cabinet saws. Additionally, the variable speed feature has made it possible for me to rip and crosscut curly maple and cherry without getting burn marks. At 250 rpm in lathe mode, I can turn heavy stock, up to 16” diameter. Likewise, as a drill press, the Power Pro provides the necessary power to drill with large diameter forstner bits with ease. At 10,000 rpm, it can spin larger diameter shaper and router bits with more power than available with traditional routers. While multi-purpose tools are not for everyone, this upgrade gives those who must work in very small shops, like my 192 sq. ft., the increased power and capability of many larger stand alone machines."
