It's too late for me, but you can still save yourself! That is if your reading this to learn how to bend wood. See, the problem I was having was, even though I was steaming the wood, it would rather just angle towards where I was trying to get it to go instead of bend in a nice arc to where I wanted it to go. As you can see in the photo below, the roof slat is almost straight. Not the curving arc as seen in the blueprints.
In this close up shot below, you can see where the roof slat would rather break its bonds and bite into the support its attached to.
I figured out a solution, but unfortunately, it wasn't until the last slat. Turns out that cutting the slats to length before installing them was the problem. The secret is to keep them long and cut them to size after installation! First, The slat is nailed and glued to its support beam. This is allowed to dry over night.
Too bad I didn't figure this out sooner. Oh well... live and learn. Yes sir. Live and learn.
