ABSTRACT:
A sanding apparatus is disclosed which includes a motor and mechanical drive system for imparting rotational and oscillator motion to an output shaft thereof. The motor shaft extends upwardly through a worktable. In one embodiment, the sanding apparatus is convertible between two or more modes of operation. In a spindle sanding mode, a sanding spindle is coupled to the motor output shaft, such that the spindle rotates and oscillates with respect to the worktable. In a belt sanding mode of operation, a belt sanding belt/pulley assembly is attached to the motor shaft. The belt/pulley assembly includes a drive drum and a driven drum about which a sanding belt is entwined. When operated in belt sanding mode, the entire belt/pulley assembly, including the drive drum and the driven drum oscillate up and down with respect to the worktable. In an edge sanding mode of operation, the worktable is articulated so that at least a portion thereof is angularly adjustable with respect to the belt/pulley system.
