JIG JOURNAL Dado & Rabbet Jig This jig simplifies the set-up and the operation necessary to make repetitive cuts. Just lock the board between the base and clamping bar, then guide the router along the bar. The stock doesn't move, so you don't have to worry about controlling a large piece of wood, and the straightedge doubles as the clamp, so the set-up is very simple. The jig is just two pieces of wood (a base and a clamping bar) with the sizes determined by your needs. Make the base from 3/4" plywood and the clamping bar from a hard, dense wood such as oak or maple. The bar should be fairly thick so it doesn't bow when tightened. I crowned the top and bottom surfaces of my clamping bar, making it 1/32" to 1/l6" thicker in the center than at the ends. Even though the bar flexes, the clamping pressure remains even. To use the jig, position the stock on the base under the clamping bar. To do this quickly and accurately, it helps to make a positioning gauge from a scrap of thin plywood or hardboard. Lock the bar down on the base and place the scrap so that one edge rests against the side of the bar. Rout all the way through the scrap, creating a strip about as long as the bar. The width of this strip is the distance from the edge of the router to the bit's cutting edge. Use the positioning gauge to align the stock underneath the clamping bar. The edge of the gauge indicates the inside edge of the cut. This jig also is a timesaver for making identical cuts in multiple parts. To make multiple identical cuts, such as the cheeks and shoulders of tenons, clamp a short fence to the base to position the parts. 78" x 5" carriage bolt, flat washer, 0.030" x 13/32" I.D.x 3/4" long compression spring and wing nut (2 sets required) Everything you need to know about the router in our special series!
