Abstract
A powered sharpening system utilizing a turntable to rotate reversible, interchangeable platters carrying different grades of abrasive for grinding, polishing and lapping woodworking and other edge tools to be sharpened that are secured in a tool holder that contacts a reference surface on a tool rest to facilitate formation of bevels and micro-bevels at desired angles. Use of a platter of a first thickness followed by a thinner platter enables automatic formation of a micro-bevel without any adjustment in the tool holder, tool rest or sharpening technique. The turntable is rotated by an electric motor that also rotates a conventional abrasive wheel or a conventional narrow abrasive belt. The motor is mounted in a base within which a duct is located for coupling to a vacuum system for removing, through ports in the duct, abrasive and metal particles produced in grinding and sharpening. Blades on the underside of the turntable induce airflow through the base to cool the motor and other components.
