This tapering jig is made completely of scrap wood. The “spring boards” are what holds your work piece to the jig base. All the hold- downs and stop blocks are held in place and tighten down with screws. The stop blocks allow for repeat cuts and can be moved around according to the size of your work piece. You only have to measure one time, the first piece. After marking out your first piece on the jig base (i.e. with painters tape), align your marks with the blade side edge, secure the stop blocks in place next to the work piece and secure the spring boards. You’re all set! The next piece is aligned with the marks and against the stop blocks to get repeat cuts.
