ABSTRACT:
A workpiece is clamped to the upper side of a horizontal base. An upper plate is spaced above the workpiece and is supported on the base to move downwardly toward and upwardly away from the workpiece. The plate is transparent and defines a surface upon which a pattern to be cut into the workpiece may be drawn. A plunge-type router is located between the workpiece and the plate and includes an upper stylus which engages the lower side of the plate. By moving the router horizontally so as to cause the stylus to follow the pattern, the design of the pattern may be cut in the workpiece. When the router is plunged downwardly and retracted upwardly, the plate follows the plunger and remains in engagement with the stylus.
