ABSTRACT:
This device consists primarily of a tool (blade, chisel, or sanding attachment) which is attached to a tool holder. The tool holder in turn is attached by a bearing to a shaft which passes thru a flywheel, the shaft is offset from the center of the flywheel thereby causing an eccentric rotation of the tool holder. The flywheel and tool holder "float" as an assembly on rubber couplings and impart to the tool components of these various motions slicing, chopping, scraping, and rubbing.
