The above diagrams represent a single sheet of 3/8 cdx
exterior plywood and an 8ft 2x8 (1.5 x 7.5 x 8). See the pictures below for how it should look completed. See Bats Magazine v11n1-3 and v6n1-2 for more information.

1)
Groove the 2x8 the long way with 3/4 spaces and 7/16 wide
by 1/2 deep grooves to fit the slats (a total of 6 grooves). I thought it was easiest to groove the whole
2x8 and then cut it to lengths (a table saw with dado blade is very helpful,
but you can do it with a skill saw). You
will also need to groove out a place in the sides for the ceiling to fit (1 1/2
wide, across the short way, just below the angle for the roof.)
2)
Cut out the pieces from the plywood as shown above. Note that slats F.1, F.2, F.3, F.4, F.5, and
F.6 should be stacked together to make one complete slat similar to the others.
The bats wont care that it is more then one piece and no one can see it.
3)
You should lightly groove (1/32 to 1/16 deep) the plywood
slats on both sides as well as the insides of the back and the front at about
1/2 horizontal intervals so the bats can hang on better. Use a skill saw or a utility knife. Groove the landing pad too. Alternately you can staple on fiberglass
window screen instead of grooving it.
4)
Screw the back to the sides with 4 to 6 2 1/2 exterior
grade screws.
5)
Drill several (8+) holes in the ceiling board to let heat
from the attic into the second chamber from the back. Do the same thing to the second chamber from the front.
