Abstract: A device for supporting a workpiece for being ground to size by the use of a grinding means, comprising a base member having a work-supporting means operably associated therewith. The base member supports the work-supporting means by a hinge member, with the base member and the work-supporting means normally being in an aligned relationship, but with the hinge member enabling the relationship of the work-supporting means to the base member to be angularly modified on occasion. The work-supporting means has thereon a work-clamping device constructed and arranged to hold a workpiece in a selected position, such that a portion of the workpiece held in the work-clamping device can be brought into direct contact with the grinding means. A depth-controlling member operably mounted upon the base member is positioned to normally contact a workpiece held in the work-clamping device.
