ABSTRACT:
A dovetailing jig has a base with a flat top surface notched along the back edge. A back on the jig has a flat front surface that is positioned above and at the rear of the top surface of the base while two side plates provide confronting flat side faces. Two clamping cylinders extend between the side plates to clamp work pieces to the top surface of the base and to the front surface of the back. In use, the jig slides on a bench surface equipped with a stationary router blade.
