The plywood pieces had soot along the cut edges, which would gunk up the adhesive LED strips and probably interfere with the paint. I bolted the pieces together and removed the ash with coarse sandpaper.
I drilled and cut a circle of hardware store plywood. There were three hole sizes for the wooden slats, clock movement, and quadrant dividers. Cutting the circle with a jigsaw on a dark patio was the hardest part. I sanded the edges to prevent slivers.
I put white contact paper on the clock face and blackened the bezel pieces with a permanent marker. Paint would have been less expensive, but it would have taken longer, and I did all these things in my living room.
I assembled the clock walls, added an inward-facing LED strip around the rim, and the black bezel pieces. I used a razor knife to carve out a groove at the top where I could pass the LED strip wires. I need something to cover the conductors and a microcontroller.
I designed and cut a couple of wood pieces for the top of the clock, where I can mount buttons and a microcontroller. These pieces were much too large, but I needed to be sure I could fit everything. If it is a problem, I can cut new ones.
I mounted the microcontroller demo board by drilling four holes and bolting it to the mounting plane. I removed the LED strip's pluggable header, soldered the wires to my controller, and added the lid.
