need to locate the rub strip on the connector with respect to the size of your saw table. As illustrated in Fig. I, move the connector-mounted rub strip inboard (toward the base) as needed so that it is 3K firmly on the saw table when the |ig is mounted over the fence in the cutting position. If you locate this rub strip so that it is at least I in. away from the table edge when the jig is 1 in. away from the saw blade, your jig should be able to function in just about all situations. The 6 in. length of the connector provides sufficient area to mount ihe rub strip no matter what the size of your saw table. Sizing the notch in the brackets to fit your fence is also easy. As shown in Fig. I. to determine the notch height, measure the height of the fence to the highest point (such as the top of a screw), and add 1 in. This is the notch height. The notch height allows for the fence, a 'A in. clearance space, and the V* in. thickness of the base support. To determine the notch width, measure the thickness of the fence and add I in. The notch width allows for the fence thickness, the V* in. thickness of the fence guide, the Vi6 in. thickness of the rub strip, plus a '/ift in. space in which 10 adjust the rub strip for a snug fit against the fence. Get To Work We used cabinet-grade birch plywood for our jig. if you have access to Baltic birch or Appleply. these would be even better choices. We don't recommend that you use fir construction plywood for jig making, since this plywood isn't made to exact enough specifications. Once you've determined the notch dimensions in the brackets, you can cut the various parts to the sizes listed in the Bill of Materials. Note that the widths of the base support and fence guide will depend on the notch size. Once the parts have all been cut to size (refer to the full-size pattern on the opposite page for the profiles of the swivel work support and stiffener). you can begin the assembly work. First, apply the solid wood edging to The Woodworker's Journal FtO. A HEvsht, Mt^uee. Vftsit TO VCxfriT A ACO 1 1K6M Tc Fttftjpc HOTtH Wt>TV>,, MEA5URE. 4 M>t> i AT LEA.-5V BSAW Ba-we |
