Bruce routes a trapezoidal pocket for to accept the end graft.
Next, sharp corners are established (I am guessing with a chisel).
Now, create the miters on the binding purflings, cut the end graft purflings and miter them (again, I am guessing a sharp chisel) and glue them in place.
A trapezoidal piece of Camatillo is cut to size.
The end graft is glued in place and clamped. Bruce will wait for the glue to fully dry before leveling the end graft to the body.
