Step 10: Attach blocking boards.

Blocking should be located 1-2 inches out from the edge of the pool's coping. Start by cutting a 2"x6" blocking board slightly longer than the distance between support boards. Set the 2"x6" blocking board on top of the 2"x6" support boards alligned with the pool's coping. With a pencil, mark the angle on each end. Finish by cutting and securing all the 2x6" support boards with 2-1/2" deck screws.
