Thx Eric. This is the 1st I’ve had explode. I’ve had a few tic before, when they lifted a splinter on the back, but this one didn’t. Looking at the inside of the 3 larger pieces, they all look dry and chalky/crunchy through out. The way the breaks stair step in and out multiple levels seems strange. I’ve worked with kiln dried lumber most of my life, and anytime I intentionally broke any, it was a much cleaner break, or feathered out down it’s length.
