Brad, discreetly video the live animal cage stunt.

I'm still trying to think of the reason I would roll the timber 180 degrees after the first side is done. The only thing I can input is out of habit, on my own part. I sometimes will roll 180 on a log because it has some bulk on one side which cause some havoc in keeping the cant square, so to balance it out I take some off opposite side. But this isn't as much of an issue when working with this kind of stock. You mentioned the other two sides were not totally square to the first two. While you are right there doing the squaring put some future reference marks on the timber dictating the best aris.
