Making the walls and roof
Step 4. Cut the plywood pieces.
You can now use the floor as a work platform.
Measure, mark and cut all the plywood pieces. Refer to the "cutting detail plans"
and the "Cutting ideas from full sheets" page
for dimensions and cutting detail.
Step 5. Assemble the front and rear walls.
Lay the pieces that make up the front and rear walls together.
Cut 1 1/2" x 1 1/2" (45mm x 45mm) battens to go around the perimeter of the front and rear walls and other intermediate pieces, as show in the drawings below.
Glue the battens in place and hold with the occasional nail until the glue dries. Then turn the walls over and screw the plywood to the battens from the other side.
Step 6. Cut a notch in the apex.
Cut a notch in the apex of both the front and rear walls. Use an off-cut of batten for a pattern (see third picture down on the right-hand-side).
Note that the roof apex is not 90°, so make the cut square with one rake (see drawing below) and be sure that the front wall notch is consistent with the back wall notch.
