I am fairly sure its too late to fix it. The unfunny part is that when carried in the door and laid on the strip of rug I'd laid out, it was saran wrapped, dead straight and flat. But the instant I cut the saran wrap off the top bundle, it turned into a bristle cone pine on a rock overlooking the pacific, twisting every which way it had room to twist. these lids, which are 2 ea 44" long pieces of 1x12 biscuited together for the width needed, have a wind in all 3 once they'd had a chance to acclimate to my 73F,20% humidity garage for a week. Worst case is 4"! I tried to clamp it to my saw table, bending it about an inch the other way, left it that way for a week, damaged the sliding tables bearings with the force, succeeded in putting 3 hairline cracks in the wood I had to superglue and didn't, at the end of that week, pull enough "wind" back out of it to measure. The rest of these have sufficient screws to pull them together anyway & in 20 years, may relax, but I'll be long gone regardless. I may bag these up & take them back to the millworks that supplied the mahogany, maybe they can find enough better stuff to make these lids again. But that will not be today, Monday maybe, give this NEURONTIN they started me on Wed evening time to try and control the back pain. Std disclaimer: If I had known I was gonna live this long, I would have taken better care of me because this back problem dates back to the summer of 1960 when I worked in an iron foundry (wife & 2 kids to support, you do what you have to do) and wound up flat on my back for about 2 weeks from trying to handle a 90 pound bucket of iron with a handle 7 feet long for about the last hour of your days shift everyday, pouring the sand molds you had made that day. The iron of course was at about 2300F. Hind sight, always 20-05. Thanks for that Brian. I had no clue where to find such a document. Good info for sure.
