I have access to the eqipment to make a drilling jig like the one Bingham sells. Does anyone know the deminsions on this jig. I noticed there is 4 holes. I would assume one set for the limb and one for the riser. If someone has a better set of plans I would love to have a copy. I probably won't be making more than 4 or 5 bow so a simple jig should work. Thanks, Don
