Once the glue has dried, you need to create the necessary edge profiling. We used a rabbeting bit and removed the material on the inside edge. We set up the bit in a router in a router table and moved the frame around the bit using the bearing as a guide. You should make a few passes with the router, raising the bit each time so you are not removing too much material at any given time. The corners of the rabbet (as shown to the right) need to be removed: we simply used a chisel to remove the material. You can also rout additional profiles on the other edges of the frame. We used a roundover bit to round over one of the outside edges. We knocked down the remaining edges with sandpaper.
