Randman-I'm pretty sure that's the bark showing the twist, but even if it is drying checks as you say it still shows a very pronounced twist in the grain as the checks more or less follow the grain. I'm sure it grew that way. If it twisted while drying, the milled surface on both sides would reflect that and they look pretty flat. I do see some serious potential for hick or boo backed Osage there. But that's out of my admittedly small area of knowledge. Having never made a laminate in my life.
Joe- once that wood reaches equilibrium with the relative humidity, it stays in equilibrium. Only varying slightly to maintain equilibrium with the rh as it fluctuates. Even if you kept it in the bathroom next to the shower for a year and managed to raise the moisture content a few percent, which makes no sense to do, it would just return to equilibrium in a little time away from the higher moisture environment. It would more than likely check all over in the process. Josh
