Jerry,
Always good to save a crotch:devil:. I think the reason they don't split as much is the grain going so many different ways.
Hot and dry should only affect the speed in which they dry, my kiln is 100- 120*F until the wood's dry and 140 to kill bugs.
Splitting seems to get me most when the slabs are thicker than 8/4", to me, split and planer snipe seem to be enough of a reality that I cut everything long in order to not ruin some choice grain figure.
This is the first time I've tried milling live oak. Most of the oak I mill in Black Oak, and usually don't have a problem with it splitting. Since I don't have a tractor to move milled wood I keep everything to 8' long max.
I would think a full barrel would be a good trade for those crotch slab tables.
I'm calling him tonight about taking the wood over. I just got a call from a friend who knows someone who has walnut trees cut down/up and found out I have a mill. It never ends...
