A Quick and Easy Band Saw ^ Fence ^ By Dave Olson When I began woodworking, one of the first tools I purchased was a used band saw, which came without a fence. Knowing that I needed this essential accessory, I set about building one right away. I made it tall and sturdy for resawing wide boards, and I added a single-point attachment that's good for cutting along a scribed line while making adjustments for blade drift. The jig has two parts: the base and the fence. Installing the base in the band saw table's groove automatically squares the jig to the blade. The fence is then placed on the base and slides back and forth to set the width of the cut. I hold it all in place with two bar clamps. Baltic birch plywood is an ideal choice for making the jig since it's dimensionally stable, flat and strong. I used hard maple for the guides and glued plastic laminate to the fence to reduce friction and improve wear resistance. My jig is built for a Rockwell 14" band saw, but it's easy to resize it for any brand of band saw you may own. Your band sawing results are sure to improve when using this easy-to-build accessory that quickly adjusts for resawing or ripping. Begin by cutting an extra-long piece of plywood 12" wide for the base and fence plate (pieces 1 and 2). By machining these two plates as one piece, you'll guarantee that they match perfectly. In addition, cut plywood to size for the fence and the braces (pieces 3 and 4). Now install a 3/4" dado blade in your table saw, raise it 1/4" and plow the guide grooves in the plywood for the base and fence plate, as shown in the Groove Elevation on the next page. Cut this plywood into the two pieces for the jig and plow a 1/8"-deep rabbet in the base for the band saw slot guide. To cut a perfect groove in the back of the fence for the fence plate, match your dado blade width exactly to the thickness of your plywood (make two passes with a narrower blade if necessary) and be sure the distance from the groove to the bottom edge of the fence also equals the plywood's thickness (see Fence Joint Detail). Getting these measurements dead-on is the key to keeping your completed fence Figure 1: For ripping operations or resawing stock that's been milled four-square, the author recommends using the standard fence. Figure 2: When working with a dull blade that tends to drift or when cutting along a scribed line, the single-point fence is often the better choice. It's also great for resawing. plumb at any position on the band saw table. After cutting the fence groove, trace the fence (piece 3) onto your stock, then band saw the pieces to shape and round the top corners of the fence as well. Next, drill all the countersunk pilot holes for screwing the pieces of the jig together, then 34 * Workshop Projects |
