The ends are sealed with at least 2 coats of wood glue. 

I know at least one of the logs had borers.  It is one I had cut several years ago and left in the woods.  I planned on dousing them in bug killer when I move them to the other storage building. 

Beautiful! Hope things work out for you.

Bug tunnels can be interesting in a table.

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.
