Boards Needed:
A -- Front legs (2" by 8" by 58") With your helper holding the structure upright, attach the front legs (A) to the inner frame (F) using one 2 1/2-inch decking screw, placed 3 1/2 inches in from the end of the leg. The top edge of each leg should be level with the top of the outer frame ends.
Square the front legs by measuring diagonally. Adjust as needed, then secure each with a second decking screw, placed above or below the first. (Note: Be careful to place the screws as shown so they don't get in the way of bolts to be added later.)
