Although it is used primarily to cut tenons, the jig can also be used to groove, bevei, or perform any number of other operations on the ends of boards. As shown in the photo, the workpiece is positioned against the stop (D) and clamped securely to the jig. A damp block protects the workpiece from the clamp jaws. Most commercially sold tenon jigs mount in the miter gauge slot. Since our jig fits over the table saw fence, it is adjustable to practically any position. The jig shown is sized to fit our table saw, a Rockwell Unisaw. Naturally you must size your tenon jig to fit the fence on your particular saw. The jig sides (A and B) are % in. thick birch plywood, while the center section (C) and stop (D) are solid hardwood. When making the jig, keep in mind that all measurements and cuts should be accurate. The jig must fit snugly over the fence, yet must not be so tight that it is prevented from sliding back and forth. Assemble the jig with glue and countersunk screws, as illustrated. No finish is needed, although an occasional coal of paraffin wax on the surfaces that contact the saw will help the jig slide smoothly. Wvj 50 The Woodworker's Journal |
