This was the natural progression of my early experiments with living hinges.
This was done with PG medium maple. The rods are 1/8 inch brass that I cut down with a small hacksaw. Superglue was (so far) sufficient for keeping it together.
I had to engrave the post holes for the rods three times to get a good depth. Probably could’ve done with just two since I discovered afterwards that I had the size tight enough that I needed to lightly tap the rods in with a hammer to get them in.
