Hi Alan,
Wow - looks like you matched nearly perfectly! Sheet 2 will be dropped in the mail tomorrow. Also, I would be happy to send you scans of all ribs, with dimensions so that you can recreate more efficiently accurate digital drawings with your software. What I am doing is rather archaic (basically tracing scans in power point - which is a pain in the butt, and likely not as accurate)!!!!
Here is my reproduction of rib #2, with the wing-jig knockoffs. Best, Scott
