– Small warped wood pieces can be straightened out in the winter season. This can be accomplished by placing the warped wood convex side down over a radiator. Cover the wood with a damp towel. Heat combined with moisture will straighten the warped wood.
– If this technique does not work even when tried more than once, trying anything else would be useless. Instead, you should get a replacement for the warped piece of wood at a lumber supply store.
