Other than Southern Pine, there is no definition for "kiln dried."
Here in the desert southwest, lumber graded "dry" (19 percent moisture
content or less) will shrink, split, twist and do other strange things as it
dries down to its equilibrium moisture content of about 6 percent. 8 inch
diameter posts will have 3/4 inch splits.
I try to make it very clear to my clients when they want 6 X 12 or larger
beams what will happen to them.
