Abstract

A template device for guiding a cutting tool in cutting engagement with a surface of a work piece to provide ornamental design in the surface of the work piece. The template device comprises a base plate having a base plate opening therein; a carriage support having a carriage support opening therein, the carriage support rotatably positioned within the base plate opening and supported therein by the base plate; a locking assembly for securing the carriage assembly to the base plate such that the carriage is maintained in a selected fixed position with respect to the base plate opening; a carriage assembly secured to the carriage support, the carriage assembly traversing the carriage support opening; and a template assembly having a template opening therein, the template assembly being selectively movable across the carriage support opening via the carriage assembly, the template assembly further being selectively rotatable about its central axis, the template opening adapted to receive and guide the cutting tool in cutting engagement with the surface of the work piece so as to provide the desired designs in the surface of the work piece.
