I've got some thats almost unusable. I mean about 500 BF. I've had it for about 5 years, and finally decided to use it. It's all 4/4 kiln dried and been stacked/stickered since. I started pre sizing stile & rail stock about a month ago, cutting everything 1/2" oversized. Skip planed to remove the scab. Boards come from large trees, at least 12" planks with little to no sapwood. Now that I'm working it, I cant get a straight board to save my life. Every board is reactionary! I've tried everything. Milling it down to within 1/8", then letting it sit for a week, re-jointing & planing it....nope, it moves! What frustration!
