Does anyone know where i can find that information before I begin making the forms?

Crimps were made with pliers after forming to straighten the rib. For location , I drew the rivet pattern on a template strip, marked my desired locations for crimps and I crimped each rib.

I made a strip of aluminum 3/4-inch wide with a straight line on it and punched rivet holes in it for marking the center of the rib and rivet locations. This was used to repeat drilling the skins for consistent alignment both ways. It also preceded crimping the ribs formed at best intervals. http://www.macsmachine.com/images/centerwing/centersection/full/top-skin-dri ll-strip(2).gif That page shows the center section of my wing, but the process holds well for any wing.

I should have asked this question at the start but here goes. I haven't crawled into my fuselage yet (think I'll wait until it is on the gear) but was curious about the optimum height of the seat back. I'm 6'1" tall, so can anyone suggest how much, if any, I should extend the seat back above the top support? With the laid-back orientation of the Zodiac seat I would think that some head support would be in order. Thanks!

The important issue, from my perspective, is the constitution of the cushion you provide for the seat. This trumps the seat back which mostly serves to cover the big hole below the baggage compartment cross piece. I got a hold of three different kinds of foam which I used in my seat cushions. There are two different memory foam (pink and blue) and heavy grade polyurethane foam on top - the kind recommended for dinner chair cushions. These are covered with Duck cloth. I wanted to try leather but I decided the cloth was more comfortable.
