Can warped boards be straightened?

[JTM]

I milled some hackberry awhile back. Two and a half inches thick and about 36" wide. They were stacked and stickered. I didn't put any weight on top of the stack. A couple have some warping now. Will weighting the stack now help to flatten them out?

Resaw or plane them

If you want to mess with them a bunch you can make them better, but be prepared to do some planing. I got some used carpet and sprayed it with water to put the slabs on to warp them the way I wanted. They started to straighten out in less than a week, but had to keep the carpet damp all the time and then lay them out carefully with fir strips to allow to dry. Thanks

So Ted,
are saying that after you straightened them by moisture swelling the concave side, that you were able to then dry them in the straightened position?

That is what I am telling you. With some patience they can be brought to near perfection. However if your wood has cracked then OH Well. From my experience if the wood is moistened then allowed to dry slowly it seems to be fine. Some types of wood will react differently, I have about 1000 BF of 2'' Pine planks that were not well taken care of that were warped quite severely, but now seem to be very usable. Thanks

Thanks for the replies.

I'd move them to the bottom of the stack (or a new stack) and hope for the best...
