Screw the template to a piece of 14" x 21" x 3/4" plywood. Then screw a backer board on the underside of the plywood. Secure it on both the inside and outside of the cut line so the plywood doesn't move during the cutting.
Set the depth of cut to approximately 1/8" and make the first cut moving right to left. (Note: we used double stick tape to attach thin strips around the outside of the template to keep the base plate level when cutting.)
Make two or three more passes until you have cut right through.
You now have the inside and outside part of our bending jig. Lightly sand the edges.
The bottom ends must be cut off to allow the six layers of 1/8" oak to fit between the template when clamping.
You can repeat this process until you have a total of three inside and two outside pieces for the bending jig. NOTE: We also need two additional outside pieces to make our cut-off jig (see Table Saw Cut-Off Jig). OPTION: After cutting the inside and outside piece they can be used as templates. Simply screw them to scrap plywood, bandsaw off excess material and trim with a flush trim bit on a table mounted router.
