Abstract: A double mortising, tenoning and dovetailing wood working machine including a base member, a sliding member and locking members. The base member is mounted on a table. The sliding member and locking members serve to precisely locate the base member relative to a piece of wood stock. The base member can be located over a piece of wood stock, locked into place and have a tenon or tail cut on the stock. The base member can then be moved horizontally over the stock, locked into position and have a second tenon or tail cut on the stock. The stock is then removed and replaced with another piece of wood stock to receive the mortise or socket joints. Through the use of the locking members and the slide member the base member can be located over the stock in the exact location needed to cut the mortise or socket joints to allow for a precise double mortise-tenon or dovetail joint.
