A simple addition to my tablesaw fence allows me to cut dozens of identical odd-angled shapes in a hurry. It works just like a flush-cutting router bit. The auxiliary fence's ledge is exactly lined up with the blade's outer edge. I use double-face tape to attach a template to a slightly oversize workpiece, then push the template along the ledge. The result is a perfectly clean cut-with no router bit tear-out-that precisely follows any template. It's perfectly safe on sides down to 4 in. long.
I used 3/4-in. solid wood to build the fence, but plywood would do as well. The ledge is screwed and glued to the horizontal piece, 1 in. above its base. This gives enough clearance for the blade to be set higher than the 3/4-in.-thick workpiece. On the bandsaw, I rough-cut each workpiece 1/8 in. larger than the template on all sides. Presawing eliminates large offcuts, so there's no chance of kickback. All I get are sawdust and perfect copies of my pattern.
