I bought six sheets of birch ply, let it sit in my garage for a couple of
weeks, then eventually cut it down into strips roughtly 12x94.
a week later, I got around to working with those strips and found a number
of them to be warped to the tune of about 1/4 to 1/2 inch, maybe even a
I'm wondering if this is normal behavior? I thought that plywood was supposed
to be dimensionally stable and not prone to warping.
one thing I did note in this stuff is that, a couple of the cuts show that
the plywood has irregular plys, ie, they're not all straight if you look down
the edge of a cut side. thereare places where one ply had a void, and the
next ply seemed to sink down a bit to fill it. the exterior still seems
flat and stable, but I'd never seen this sort of thing before...
any comments appreciated.
