I've worked on the dimensions for the mockup that I am going to cut tomorrow. Here's what I ended up with.
Oh, those dimensions in red. Sorry about that. It's a result of the other dimension and the angle. I want to be able to tilt the blade on the tablesaw to a whole angle when I cut those pieces. I'll just have to get as close as I can to those strange numbers!!!

Mike...
P.S. By the way, I have 2 pieces of OSB, 48" x 116", with a little help from my biscuit joiner and some gorilla glue.
