The V shaped wiskers will need to be mounted ahead of the reflector. A brace 29" long (the distance from the top to bottom wisker is 27") is made from the same material as the back brace.

Picture 1
Use a large drill (forstner bit works nicely) to drill a recess for each of the eight wiskers. use the diagrams from step two to determine the distance apart they should be. About a 1/4" deep should be enough. Notice that the recess is of the side of the brace. This is to accomodate the wiskers sticking out.
