Abstract
An angle gauge comprising multiple surfaces around its perimeter, each of which provides for two or more fixed sharpening angles; each angle incorporating angular compensation for workpiece thickness and variations in peripheral grinding wheel diameter in order to quickly and accurately set an angular relationship between an curved or planar abrasive surface and a tool rest. The angle gauge has no moving or adjustable parts and is separate from both the grinder and the tool rest. The angle gauge may also be attached to a holder allowing for angle setup when the workpiece cannot be supported by a platform or tool rest.
Claims11
An angle gauge, the angle gauge comprising:
- at least four flat exterior perimeter surfaces, wherein each flat exterior perimeter surface shares at least two corners with other flat exterior perimeter surfaces;
- wherein each corner between the flat exterior perimeter surfaces is capable of defining at least two angles between a first independent flat surface and either an adjacent second independent flat surface or an adjacent independent curved surface;
- wherein the angle determined by the corner is determined by which of the flat exterior perimeter surfaces of the angle gauge is placed flat against said first independent flat surface.
A method for using an angle gauge comprising:
- locating a marking defining the angle to be set on an angle gauge;
- placing the angle gauge flat against a first independent flat surface such that said marking is closest to the vertex of a first independent flat surface and either an adjacent second independent flat surface or an adjacent independent curved surface;
- and
- moving the first independent flat surface so that the angle of the first independent flat surface and either an adjacent second independent flat surface or an adjacent independent curved surface is determined.
