Step 4.

Steps 4-6

4. Cut and install boards. Trim the rest of the boards, using the already-cut boards as guides. After positioning them tightly, install them with 3-inch galvanized deck screws.

Step 5.

5. Build the second section. This will only have two bench supports, so screw pieces of 2x4 onto the bottom of each end for temporary support.

Step 6.

6. Set the sections. Set the two sections in place by resting them on chairs. When the whole assembly is positioned correctly, hang a plumb line from the center of each bench support and dig up a bit of turf to mark each posthole. Shift the whole assembly to avoid large, exposed roots.
