I have read a few posts on a forum of people who use plywood for
hives/supers.

Up here in my area we have CDX plywood. I have been considering using
it (I could make 5 3/4 deeps from one $25 sheet). My only concern is
the out-gassing of the glues. I know exterior glue releases it's gas
much slower and is considered to be much less a problem. The hardware
store says CDX stands for (C was something, D something, X - exterior
glue). So it should be ok in that regard.

Anyone know of any evidence that the out-gassing can cause problems? I
know wooden ware commercial operations offer bottom boards, inner
covers with plywood. Also noticed the FDA plans for a home built honey
extractor uses plywood.

Thanks

Leave it to off-gas for a few months then paint it to seal in anything
that's left.

but why would you use a 25$ sheet of ply when you can use a 10$ piece of
3/4" knotty pine?

$10 pine = 1.25 deep hive body (that is $8/per).
$25 plywood = 5.75 deep bodies (that is $4.35/per) -or- about 7.75
mediums (that is $3.23/per) -or- 10.5 shallows (that is $2.39/per).

I have to keep costs as far down as possible :)

The best thing to do, of course, would be to make two hives with plywood,
two with traditional wood and compare average yield and survivability....and
I would be interested in the results if someone did that.
