ABSTRACT:
A set of plates that interact to control the action of a router to direct it to shape interlocking components in sheet materials. The device is mainly applicable to dovetail joints but it can be applied to lettering and decoration. One of the plates supports the router over the workpiece. A second plate forms a shaped base for the router. Two further plates control the movement of the router plate and hence the router itself on the base plate. Another of the set of plates is indented with depressions that act as a template that controls the position of the cut of the router by means of an attached locating pin that can follow the template. The positioning of the router and the way it attacks the sheet material is unrestrained until checked by the plates. These plates together can form a set of dovetail jigs that cut both through and lapped dovetails using any dovetail cutter.
