Standing and fixing the walls
Step 8. Fixing the walls in place.
Clamp a couple of blocks to both end joists to prevent the front and rear walls from slipping off the joists while they are being worked on.
Stand up the rear frame and hold it in place with a temporary brace.
Do the same with the front wall.
Mark a couple of pencil lines across each of the two side walls 11 1/4" (280mm) in from the front end and 8" (200mm) in from the rear end
(see drawing below). Also refer to the side elevation plan.
Clamp the side walls in place ensuring that the insides of the front and rear walls line up with the pencil lines on the side wall (as mentioned above).
Bolt the side walls to the 1 1/2" x 1 1/2" (45mm x 45mm) battens on the front and rear walls using 3/8" (10mm) galvanized bolts. Pre-drill the bolt holes first.
Allow for four bolts at each corner.
Shave or shape (with a planer or sander) the top of the side walls to be flush with the rake of the top of the front and rear walls (see drawing below).
