Publication number: 20220324079Abstract: A belt sander for sanding a workpiece and defining a center of gravity within a first plane. The belt sander includes a housing, a handle defining a second plane, and a drive unit disposed within the housing. The drive unit includes a motor disposed adjacent a first sidewall of the housing, a pulley system disposed adjacent a second sidewall of the housing opposite the first sidewall, and a transmission disposed between the motor and the pulley system. The belt sander further includes a belt drive system driven by the drive unit and including a drive wheel, a driven wheel, and a platen. The platen defines a third plane extending perpendicular therefrom. The transmission and pulley system are disposed on one side of the first plane and the motor is disposed on an opposite side of the first plane. The motor is intersected by the second and third planes.Type: ApplicationFiled: April 11, 2022Publication date: October 13, 2022Inventors: James C. Sitter, Jeffrey S. Holly, Joseph G.
