Exactly what Greg said, all the parralels for this design go on the back and only the tapered lams on the belly.
I built one of those 64" Bingham's one piece in October last year, it turned out nice and shoots good. I did just what you are doing; watched the video, searched this forum for information, and asked questions when I got stuck. Greg
stepped in and bailed me out of trouble a few times when I got off track. I'm sure your bow will be a success too. Put up a few pics for us along the way and good luck with your project.
