Wing framework and tanks


The wing kit arrived in June, 2007. I had prepared by building the two wing jigs you can see in the photo. I decided to build both wings at the same time, so four vertical posts were set up to support the main spars at each end. The main spars are preassembled and gold anodized. In this picture, a lot of work (mostly tedious) has been done, such as deburring, priming and riveting all the wing ribs and rear spar parts. The top skins have just been clecoed to the framework at this point, I haven't even removed the blue plastic.
Assembling the tanks was a time-consuming process. Every mating surface had to be sealed using a fuel-proof adhesive known as Pro-seal. It has to be mixed before use, has a pot life of about 45 min (at least in my garage in the summer it does), has the consistency of taffy, and it stinks. The picture shows the right tank before the rear baffle is sealed and riveted on.

Both tanks have been completed and passed leak testing!
