Before leaving for the night I glued up that half lap joint for the front rim piece that I had cut previously. I used a piece of the freezer paper as a mask and clamped it to both the table and the longer piece that will be the rear rim (to make sure the glued piece comes out straight).
After ripping the rear rim piece to match the rake of the lid, I roughed out the half laps on the table saw before finishing them with the router. The half laps got a little crazy on the shallow miters, but I wanted the challenge and did not want to fight with pocket screws that always seem to pull the joints out of alignment.
This is all just loosely dry fit for now. I need to source a hinge and latches so that I can figure out blocking for that.
