Rob Cosman's Wood-Hinge Individual Jigs: 12mm
Master craftsman Dale Nish taught me how to make an amazing wood hinge for boxes. A wooden dowel is cut into segments, a shallow hole is drilled in the center of each dowel and a small pin is inserted into the hole for the dowel segments to pivot on. I've made thousands of boxes using this style of hinge and I have designed four jigs to precisely drill the hole in the center of dowel segments (the most difficult task). All of these jigs are available together as a Wood-Hinge Drill Kit (Metric).
Four individual wood-hinge drill jig sizes available: 6mm, 8mm, 10mm, and 12mm
Each individual wood-hinge drill jig includes one dowel jig, drill bit holder, drill bit, and hex wrench.
6mm and 8mm drill jigs come with a 1/16 inch drill bit.
10mm and 12 mm drill jigs come with a 1/8 inch drill bit.
Opposing set screws hold the drill bit securely in the holder and allows for adjustment of the hole depth.
Port holes in drill bit holder expel the sawdust to prevent clogging.
