Before completing the tapering jig, there is one additional piece of stock that needs to be added to the left half of the jig. This piece of stock will actually push the board being tapered through the saw blade on your table saw.
Cut a 2" wide piece of stock from your 1x3 or 1x4, and attach this piece to the left side of the jig, up one inch from the end of the board with a couple of deck screws using your cordless drill or power drill. This board can be positioned flat against the left edge or butted against (as shown in the image above).
