JIG JOURNAL Tapering Jig A tapering jig consists of two long arms, hinged together at one end. A ledge is glued to one arm near the end opposite the hinge. A metal brace lets you adjust and lock the angle between the two arms. The arm without the ledge guides the jig along the rip fence, while the other holds the stock at an angle to the saw blade. To make the jig, cut the parts to size and drill a hole for the handle in the holding arm. Glue the ledge to the hold ing arm and the grip to the guiding arm. When the glue is dry, install the hinge that holds the two arms together. Purchase a curved box lid support and remove the metal mounts from the brace. Using a panhead screw, fasten the fixed end of the brace to the holding arm, a few inches from the ledge. Tighten the screw until it's snug, but not so tight that the brace can't pivot. Insert another screw through the slot in the brace and drive it into the guiding arm. You may have to experiment with the placement of this second screw. Find the location that allows you to open the arms as wide as possible, but keeps the end of the brace from straying over the outside edge of the guiding arm when you close the jig. To lock the arms in place, open or close them to the desired angle. Then tighten both of the panhead screws.
