If you're not willing to spend a few minutes to make a test piece to prove it for yourself, I'm not interested in wasting more time trying to convince you by making a video. You likely won't believe a video either. Throw a quick test together using scrap wood
shaped like a typical rib. You'll find that when you load the center, the ends will rotate in rather than pushing out. It works with or without a panel, and it's still not an arch. Try it, it's cool.<BR><BR>Ron N<BR></td>
