Cut spot-on tenons and half-laps using your tablesaw sled

Most tablesaw tenoning jigs ride along the saw's fence, but you'll get smoother, more-accurate results using this jig in conjunction with a crosscut sled. The jig consists of just three pieces, with threaded knobs, washers, and bolts in slots to allow for cut adjustability and jig removal.

When building yours, be sure to glue the 2×6 exactly 90° to the sled base and plywood backer. Use a fine-point pencil to mark cutlines. Get a precise fit for project parts by gradually adjusting the jig.
