I have a special (to me) 12/4 14" QSWO plank I'd like to resaw. It was stickered in an outside shed for 3 years, then brought into the shop ~ a year ago. It reads 10%RH. How should I store it to minimize residual moisture gradients and internal stresses befoe I resaw in in 6 months or so? A friend mentioned wrapping it in saran wrap for the duration and storing in the shop, which should be close to 30%RH for most of the winter (on Cape Cod).
I'd much prefer not to cut test sections to check stresses, but I'm game to buy a tool (up to $500 or so) that could check this noninvasively.
(FWIW, the resawing tool is a 5 hp Laguna 18 with an appropriate fence and sliding support. It's cut that width oak before. )
