Abstract: The combination of a rip fence and a workpiece pusher are provided for a table saw or shaper. A preferred workpiece pusher moves along a track having a central portion aligned with the feed direction and having two end portions skewed with respect to the feed direction so that the workpiece pusher retracts into the rip fence at both limits of its travel. This allows a sawyer to retract the workpiece pusher on the infeed side of a table saw and begin a ripping operation in which he or she manually pushes the workpiece into the saw blade until the trailing end of the workpiece is close enough to the saw blade that the workpiece pusher can be moved out of the fence to engage the trailing end of the stock. The pusher can then be used to push the workpiece the rest of the way past the blade. This apparatus also allows a woodworker to operate a table-mounted cutting tool without using a workpiece pusher of the invention that is installed on that table.
