Built a full scale model in pine to test the geometry and joints, wrapped in packing wrap. 

8/4 walnut #2 commons at $5 b/f, took my time finding decent lengths. I think it took about 15 board feet.

Milled to manageable pieces.

Laying out the pieces based on the templates I made from the pine model

Cutting the joints, took about 3 or 4 passes with the dado stack.
