Rob Cosman's Wood-Hinge Individual Jigs: 1/4 inch
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).
Four individual wood-hinge drill jig sizes available: 1/4", 3/8", 1/2" & 3/4"
Each individual wood-hinge drill jig includes one dowel jig, drill bit holder, drill bit, and Allen wrench.
1/4" & 3/8" drill jigs come with a 1/16" drill bit.
1/2" & 3/4" drill jigs come with a 1/8" 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.

1/4" wood hinge jig
it works great as a 1/4"jig. my only concerns i have (which may be unfounded) are the set screws clamping onto the flutes of the bit and the length of the drill bit does not allow me to chuck in in my drill. i had to cut off a portion of the end of the bit or i had to use the bit itself to operate the jig. in hindsight the 1/4' was too small for my boxes so i ordered the 3/8"jig last week. thank you and keep up the most excellent work.

I assumed that the interior diameter of the jig would be a hair greater than the diameter of standard quarter-inch maple and walnut dowels (commercially manufactured) in order to allow the dowels to fit easily into the jig; not so. Still attempting to find a way to uniformly reduce the diameter of a standard quarter-inch dowel by a hair to allow it to fit into the jig. I've tried wrapping sand paper around a dowel inserted into my drill but could not achieve uniformity over the dowel's length. For now, amid my discouragement, I'm considering building the Cosman dowel-making jig to complement the wood-hinge jig. Much ado.
The product works as advertised. I’m just having trouble fitting the lid to the back of the box in the groove. It seems to fit right but when I glue it and open the lid it comes off. I just need to keep after it. Thanks
Wood hinge jig idea
Great product but without the dowel making jig aren’t worth much. Yes making the jig to make dowels is a giant pain. Thank god he gives good directions. Rob-Find someone to make these for you and sell the jig to make dowels with the wood-hinge jig.
