Or at least, they probably aren't. In a few days I'm going to go look at a load of Black Walnut someone had cut off her land and dried in a local kiln. She's already told me she doesn't believe the ends were sealed. It's all rough cut to 5/4. I want to get a look at it even if it's just for my own education. I've got an idea what the local prices are.
What should I look for besides splitting ends? I'll have a ligno meter with me, and a flashlight and even a block plane so I can check the grain, but besides looking to see if the boards have begun to split, and if they're somewhere around 8 percent moisture, and maybe measuring a few to see if they're really about 5/4 or so, are there any other checks I should make?
