Clark,

The timbers are boxed-heart.

In a couple of the timbers that twisted badly, the heart did not run down the center of the timber. Instead, it might run from the lower-left corner on one end to the upper-right on the other. I think that was a big part of the problem.

But, as you said, most of the BH timbers were a little wild.

It's just another of those things that I'd do differently "next time."

Thanks for the reply!

Jon
