Double Hinged Lidded Box

This is another project to use up some wood scraps.  It is also a personal challenge to see if I can make a working hinge for the lids from scraps. The box is red oak.  The lids are white oak.  The hinge plates are 6mm thick Baltic Birch plywood. Shorts lengths of 1/8" diameter stainless steel dowels are what the lids pivot over.  

Lids Open

A problem encountered was inconsistent pockets cut using my CNC.  The pockets for the hinge on the box end used the same vector as the pockets on the lid ends, but one set is narrower than the other.  I'll blame this on the two bits used.  One or both are not exactly the diameter they claim to be. 

Half way opened (or closed?)

The plywood hinge plates were cut from a scrap of 6mm thick baltic birch plywood. Each has a centered hole for the hinge pin, a rounded edge to fit in the slot cut for them, and a very shallow face pocket to thin them to ft in the slots cut for them in the box.  The shallow pocket and the rounded edge were cut on both sides. 

One Lid Closed

The lids were cut roughly 1/32" wider than the box to account for any misalignment when installed.  After some finish is applied to all parts the steel pins will be inserted flush and the lid edges will be flush cut to the box sides. 

The parts were relatively easy to create toolpaths for and cut out.  This project was a good learning exercise.  My next hinged box will benefit from what I learned making this one.
