ABSTRACT:
An edge joining fixture is provided comprising a spacer which is secured to the ends of a pair of boards by a clamp with the ends of the board abutting the spacer so that the ends will be properly aligned. A body member having drill bit bushings formed therein is positioned between the board members and rests upon the upper edges of the board members and is then clamped into position. A drill bit is then moved downwardly through the bushings to create dowel holes in the edges of the boards. A clamp on the body member is then released and the body member moved to the next dowel hole location where the body member is again clamped into position. The procedure is repeated until all of the desired dowel holes have been formed.
