ABSTRACT:
An unlimited width dovetailing system for holding a workpiece and guiding a router while cutting dovetails in an upper edge of the workpiece includes a base plate with a pair of blocks attached thereto, and a beam which rests on the base plate, abutting against the blocks. A dovetail template for a router is affixed to the beam, which can be turned end-for-end to expose either side of the template to the workpiece.
An overhead clamping mechanism for holding the workpiece in a vertical plane against a front face of the beam includes a pair of bars each having a fixed jaw pivotally bearing against a respective one of said blocks and having an offset which extends over the workpiece's upper edge, a pair of movable jaws, one on each of the bars, an elongate clamping member extending between the jaws, and a pair of clamping screws, each passing through a threaded hole in its respective jaw and into said elongate member.
