ABSTRACT:
A guide is provided for a shaping tool having a substantially cylindrical housing, a rotatable shaping member extending from one end of the housing and a drive motor for rotating the shaping member. The guide includes an elongated hollow member, a shaft telescoped within the hollow member such that a portion of the shaft projects outwardly from one end of the hollow member, and a tip adapted to at least partially surround the shaping member such that the shaping member protrudes a predetermined distance beyond a distal end of the tip member. A first mounting bracket is provided for mounting the hollow member with respect to the housing and for retaining the shaft in a predetermined fixed position with respect to the hollow member. A second mounting bracket is provided for mounting the tip member for co-movement with the shaft such that the predetermined distance which the shaping member protrudes beyond the distal end of the tip member is determined by the length of the shaft which projects outwardly from the hollow member. By adjusting the length of the shaping member protruding beyond the distal end of the tip member, the depth of penetration of the shaping member into a work piece, such as a piece of jewelry, is controlled to provide a uniform cutting depth.
