Abstract: A workpiece-holding fixture for use with a table saw to cut straight, parallel or tapered sides on a workpiece. The fixture comprises a channel-shaped body having clamps for removably securing a workpiece in the body, a shield supported by the body for overlying the saw blade, and retainers cooperable with the table saw fence for preventing interference between the fixture and the saw blade. A guide is provided for use in supporting successive workpieces to enable them to be uniformly tapered.
