The angle piece tenons were glued and the top support dovetail pin lowered into the tail cut into the vertical. When seated, the brackets were at a perfect 90º angle and the tops flush with the top stud in the stub wall. I drilled holes into the far side of the horizontal and vertical members with a Kreg step drill and put a 2" face frame screw through each tenon, forever locking them in place. The drill holes were plugged flush to the surface with tapered plugs of Bubinga and varnished with the final finish coat.
