It’s been slow going for me gaining any traction on the Rob Cosman style invisible wooden hinges, but I did make some progress yesterday. This little jig made of laminated maple ( 4 1/2” pieces ) does a great job of making holes dead center of a dowel.

The large holes are made with a brad point bit, into the end grain, which helps to center the small hole by virtue of the fact that the brad point bit leaves a pointed hole dead center.

This particular jig is for 1/2” dowel. The bottom piece is drilled almost all the way through to help it act as a holder and stabilize the dowel.

The top piece is drilled about half way through, and then a smaller, regular bit is used to drill a hole the rest of the way through the size of the hinge pin you are going to use.

Once you insert your dowel piece into the half with the deeper hole, put the other piece face down on top of the dowel, and use the small hole showing to position your drill. Use a drill press.

Boy I was tempted to, but I was in a hurry to see if I could do it that day. Turns out I couldn’t anyway because I didn’t have the correct router bit to rout the channels for the dowel.
