Step 10: Place remaining support boards.

Along the angled end boards, find the locations for the remaining support boards. (You will NOT find the dimensions for these boards on the plan. This is intentional. Due to slight differences in construction methods, the lengths of these remaining supports may vary.) Before cutting anything, place the 2"x6" support board on top of the 2"x6" angled end boards at the found location. Using a pencil from below, mark the angle and location of the cut. Next, cut both ends with a 45 degree angled cut.

After cutting the remaining support boards, position into the frame and secure with two 2 1/2" deck screws at each connection.
