ABSTRACT:
A router jig comprising a baseplate having an open interior, a first horizontal guide adjustably attached to the baseplate, a first vertical guide attached to the baseplate, and a clamp adjustably fastened to the baseplate for receiving a workpiece. Both the first horizontal guide and the first vertical guide extend across the open interior of the baseplate. A second horizontal guide is also adjustably attached to the baseplate. This second horizontal guide extends across the open interior of the baseplate and is in adjustable parallel relationship to the first horizontal guide. A second vertical guide is also adjustably attached to the baseplate so as to be in adjustable parallel relationship to the first vertical guide. The clamp includes a first board and a second board that are adjustably fastened to the underside of the baseplate. The clamp includes a suitable adjustment mechanism for fixing the position of the workpiece within the clamp. This adjustment mechanism includes a camshaft that is mounted to the first board of the clamp along one side of the first board and a dowel pin that is connected to the camshaft and extends through the board so as to open it to the area between the two boards. A subclamp is mounted beneath the clamp so as to extend in a direction transverse to the clamp. The subclamp receives a portion of the workpiece therein.
