Nice looking stuff. Spray it with good bug spray. Dry it slow. No air movement. No sun. No heat... for several months. Some of those may crack open anyhow, not much you can do about it. I had some beaut hickory logs milled into planks like that two years ago. A couple split. A couple warped a little. But most are still really nice. They're still in a part of the garage with no heat, air, or humidity control. I could move them to the shop now I suppose, I just don't have room.
