Moisture / Kiln / Monster wood questions
I am working with a 6" thick, end cut, piece of Maple or Ash. Basically the bottom of a tree that's been cut off into a disk. It was 2 trees growing together and yes, the thing weighs 60-70 lbs. I sent the piece to a local guy who runs a kiln and he cooked it for 3-4 weeks in his dryer. I believe the temp. was 185 degrees. I started working on the piece, leveling off both sides, then put it aside for 4-8 weeks in my dry basement. I went to start working on it again and I noticed that one side of a check in the wood (1/4" wide x 8" long check) had risen about 1/8" at the edge of the block. Now it's been humid this summer, not sure if that matters, but I'm worried that my wood wasn't suffiently dried.
It will be a disaster if the wood shrinks once I've finished my work on it.
I don't know of a moisture meter (that I could afford) that can read 3" into wood.
Does the kiln time sound right?
The guy running the kiln said he'd have to wing it, but he was pretty confident that it was dry.
Any thoughts suggestions?
