Abstract

A single mortise or a plurality of conveniently spaced mortises may be created in a single workpiece. A corresponding single or plurality of tenons may be created in a second workpiece to be joined to the first workpiece. The method of creating the mortises and tenons involves the use of a tool, containing a rigid plate against which a workpiece may be secured, and a template positioned so that the lower face of the template is adjacent to the rigid plate. The template contains a mortise guide, consisting of openings in the template through which a router may be inserted to carve mortises in the workpiece. The template also contains a first tenon guide, against which a router may be guided to carve one half of a tenon or series of tenons in a workpiece. The template also contains a second tenon guide, consisting of a pattern of the same size and shape, and opposite in orientation, to the pattern of the first tenon guide. The template may be moved with respect to the workpiece secured to the rigid plate by means of template slides movable along rods extending from the rigid plate.
