Abstract
A woodworking fence includes a dovetail slot into which a stop block and a push fixture each having a dovetail protrusion are in slidable engagement. Operation of a thumbscrew extending through the stop block wedges the block protrusion into firm fixed engagement with the fence dovetail slot. A bottom section of the stop block is undercut to form a relieved space which prevents accumulation of chips resulting from a cutting operation. A workpiece is pushed into a cutter by the push fixture which slides along a work surface and is kept in alignment by the push fixture dovetail protrusion sliding in the fence slot. The push fixture is relieved away from the work surface to avoid damage to the push fixture as the cutting tool cuts the portion of the workpiece adjacent to the push fixture. An erasable polycarbonate strip is disposed on the fence and has a permanent arrow locating the center of the cutting tool, to assist in locating the workpieces and stop block.
