ABSTRACT:
A motor operated abrading device for abrading surfaces, such as vehicle bodies, which device utilizes a cylindrical housing of the motor on which to secure a sheet of abrasive material, so when the cylindrical motor housing is rotated an abrading element is formed, without having to drive the abrading element with chains, gears, belts or the like. The motor will have any suitable source of power, such as electricity or air, so long as the outer housing is cylindrical and rotatable with respect to a stationary shaft. When air is used as the motive power, the air, which is cool, passes through the motor, and will maintain the motor cool as well as the cylindrical drum and the abrasive surface which is mounted thereon. The motor may be used with or without a guide frame to control the abrading element with respect to the surface being abraded. When an air motor is used it has a unique manner of conducting air into and through a non-rotable shaft to the rotating drum, which is driven by an internal motor mechanism. The guide enables contouring concave convex or planar surfaces.
