   What kind of wood was it? What did you specify for the moisture content? Where and how did you stack it when you got it?

   I didn't specify the moisture content; didn't know you could do that. Maple posed the worst problem, followed by cherry.

   This might be a temporary state for this lumber. If lumber takes on moisture unevenly this dancing is precisely what I'd expect to see. Take one of your pretzels and place it in such a way that all the faces have roughly the same amount of air flow. Once the moisture balances itself within the board it may straighten out again.

   Here's an EMC Chart that will tell you the moisture content of the wood at EMC in various conditions.

   If you got kiln dried wood from Wisconsin and brought it to a moist environment like Florida, your wood should have been immediately stacked and stickered with weight on top in a manner that allows air to freely circulate within the stack. It is likely that your wood was kiln dried to 5-6% but will want to move to 12% or more in your area. This could take a couple of months to fully acclimate.

   I suggest you go to the WOOD Magazine site and download their "Downloadable Seminar" on "Wood Movement". It will tell you how to deal with moisture in wood and includes a couple of charts of the movement rates associated with many species of wood. Go to: http://woodstore.woodmall.com/

   Howie, that's what I suspected. The wood is not kaput, but I just have to get it acclimated? Makes sense becasue it was stacked and not all boards are warped.  So it's the one-side only exposure warpage, apparently. It should flatten out after a while.

   What about heat? as in a loft that is close to the roof and gets pretty warm, around 130 I'd say. Does this contribute to the problem? All my stock was recently placed in the loft, aka, attic.

   Normally, heat is not a problem but high heat can cause some problems. I would reconsider storing the wood in a loft with high heat. Also, it might not get the air circulation there that it needs. If you can provide some ventilation into and out of the loft, then it would be OK.

   The issue is air circulation to all sides of the boards and the relative humidity in the environment.

   Keep in mind that the longer a board is warped, the more likely it will stay warped. There is actually some cell deformation that is non-reversible. Get it stickered and weighted down. BTW, that's another negative about the loft. Will the beams support the weight?

   Hmmm, the temp goes to about 125 at the worst, but usually around 110-115. Hell, my shop was 103 yesterday.

   Yeah, it supports the weight because I have a special rack built so they can lay flat. My stock only consists of about 30 planks or so and most seem to be doing ok.
