Step 4: Hang Horizontal Joists

For this step you'll most likely want one or two helpers to keep everything square as you hang the joists on the back of the wall. This is an important step because if you do it wrong your wall will most likely collapse. Pardon the lack of pictures while actually hanging the joists but we simply did not have enough hands.

-Fist position the 2x4 where you wanted it to go and secure it with 2 two of the 3" screws going straight through the side and into the 2x4 horizontally.
-Once the stud is in place install the joist hangers by first hammering in the stops and then securing it with 1.25" screws into the side and then with 3" screws into the 2x4. Check the pictures for more detail.

For the top two joists simply screw the connector into the side then up into the 2x4. I also used two of the 3" screws going horizontally through the side and into the joists.

I chose to use 4 horizontal joists for the overhang and 2 joists on top which the plywood sheeting would then be screwed into.
