Abstract

A ski or snowboard edge sharpener may include an abrasive grinding wheel, a belt-driven drive train or direct drive system that connects a motor and grinding wheel drive mechanism and decreases the grinding wheel's speed of rotation relative to the speed of the motor, a grinding wheel mount allowing selection and use grinding wheels of different grits and materials and grinding wheel controls allowing the control of the cut depth and the grinding wheel angles relative to the longitudinal and transverse planes of the ski edge surface to be sharpened. In some embodiments, the sharpener may alternatively include a grinding wheel and motor that drives the grinding wheel drive mechanism. Such configurations may allow repeated sharpening of a ski edge at specific/chosen angles with a specific/chosen surface finish. A position lockdown device that is part of each of the control mechanisms may be included.

Abstract

A portable ski and/or snowboard edge sharpener and method. The edge sharpener includes an abrasive grinding wheel, a belt driven drive train that connects the electric motor and the grinding wheel drive mechanism and decreases the grinding wheel's speed of rotation relative to the rotational speed of the motor, a grinding wheel mount allowing the operator to select and use grinding wheels of different grits and materials and grinding wheel control mechanisms allowing the operator to control the cut depth and the grinding wheel angles relative to the longitudinal and transverse planes of the ski edge surface to be sharpened. This configuration allows the operator to repeatedly sharpen a ski edge at a specific and chosen angle with a specific and chosen surface finish. Other features include, position lockdown devices being part of each of the control mechanisms and a vacuum system to capture residue from the grinding operation.
