An improved woodworking fence system for shaper or router tables which safely, quickly, and accurately produces plunge cuts and other operations without the need to replace the standard original equipment fence and safety devices is provided. These original equipment fence and safety devices are mounted to a sliding plate which is constrained to move in linear motion toward or away from the cutter by a feed mechanism. Unlike prior art fences, the feed mechanism of the disclosed apparatus can be operated under power, thereby allowing plunge cut operations, zero clearance fence construction, biscuit joining and other similar operations to be performed. Feed stop collars and a precise measurement system are provided on the feed mechanism to accurately and repeatedly perform plunge cuts and many other woodworking operations. The precise feed and measurement system allows the operator to quickly and accurately set the desired fence position without the time consuming and wasteful iterative method required on prior art fences. Since the disclosed apparatus utilizes safety devices, jigs and fixtures already owned by the woodworker It is versatile and economical to own. The fence mounting and feed mechanism allows the apparatus to be an after-market attachment or an integral part of the shaper or router table.
