I have a slight gloat, but will keep it to just telling that I had given [free] a whole pile of rough lumber; oak, cherry, walnut.
Looking for minimal waste. Some boards, just a few, are warped [twisted]. Is there a way to untwist? I know warped can be straightened with water on one side and heat on the other ["Furniture doctor".] I can't see putting a warped, twisted board through a thickness planer since it will want to wobble.
Some, like the oak have a bit of black water stain. I'm assuming that can be removed with oxalic acid? How about black dry mold?
Thanks.
