ABSTRACT:
A convertible woodworking jig comprising multiple components suited to making specialty woodcuts necessary for the manufacture of rails and stiles of cabinet door frames from standard milled wood stock. The jig has a base having a planar work surface, a first fence having a first straight edge, and a second fence with a second straight edge, between which edges a first cam assembly is medially positioned. The cam body is rotatably positionable for wedging a freely-positionable pressure block tight against a work piece, which is selectively positioned against one of either the first straight edge or the second straight edge. The work piece being so secured, a biscuit slot may be cut into the mitered end by use of a guide assembly disposed at an operative end of the second fence, which assembly closely guides a hand-held, power cutting tool at a predetermined angle formed relative to the plane of said second straight edge. The second fence further includes a third straight edge against which a stop assembly having a stop wall is positioned near a free end of the second fence. At the operative end of the second fence, a second cam assembly is positioned adjacent the third straight edge, which assembly can be manually operated to wedge tight a work piece positioned against the stop wall. The work piece is then ready for slotting by a hand held router.
