Abstract: A table saw guide apparatus includes a generally flat guide plate adapted to overlie the tabletop of a table saw, and an upstanding stop device is disposed adjacent to, and space laterally by a short distance from the saw blade. A projection is disposed on the underside of the plate and is adapted to fit securely within a tabletop groove for ficing the plate on the tabletop. A substantially flat workpiece carrier is disposed on, and in overlying relationship, with the upper surface of the plate. The carrier has an edge adapted to engage the stop device for slidable engagement therewith. The upper surface of the workpiece carrier is flush with the top edge surface of the stop device to permit the workpiece to rest on top of both the top edge surface device and the upper surface of the carrier. A gauge device is mounted removably in the upper surface of the carrier for engaging the workpiece and for helping position it angularly relative to the saw blade.
