After resawing pecan on my bandsaw, it instantly cups. At first I thought the blade might be flexing, but both pieces will cup symmetrically towards the blade. If I mill the pieces, they'll just warp again. Waiting weeks and trying again doesn't seem to help either.
I now have a number of very thin boards that have been inside for months, but if I try to joint them they'll still warp. Is pecan just like that? Could it still not be dry after so long? Or is it just a thing with thin boards? I've tried it with poplar as well with mixed but generally better results. My thicker pecan boards are warping too, but not nearly as badly.
I'm presently trying it with maple. So far the same thing after resawing it, but I haven't yet seen what it'll do after milling it again.
I've tried clamping the thin pecan flat for some time. It helped a little bit with some of them, but not that much or reliably.
