Step 9: Attach the Cross Brace

Clamp the 2x4 cross brace between the tops of the center battens. Countersink pilot holes through the face of the top slat into the end grain of the cross brace at both ends. Then secure the piece with 2½-inch deck screws. Set the base upright, and position the three cap pieces along the back edge and the two sides. Countersink these and secure them with 1¼-inch deck screws.
