Each work area at TechShop has a bin with random supplies for members to search for useful parts to use in their creations.
This jig holds thicker covers at a 30 degree angle for a version of Coptic book binding where the stitching doesn't show on the covers but is all located on the spine.
Step 1: Parts Salvaged and Tools Used
The tools I used consisted of a miter saw, a belt sander, a drill press and a handheld hex driver.
First I cut off a section of the large piece of wood at a 30 degree angle, placed it on top of the base, drilled a hole through it and partially into the base for the pin (this is just to keep the small part from getting lost while the jig is in storage).
I then cut about 6 inches off the base to be used as the anchor. I remove some of the sharp edges on the belt sander.
Turning all the pieces on their edges, I clamp the anchor to the base, drill some starter holes for the screws through both the plywood and the base/anchor assembly, drive in the screws and repeat on the other side.
