So I was trying to do a dry Tank Assembly tonight to make sure everything would fit up once I started applying the ProSeal and I am having the hardest time trying to get all the Ribs in place while trying to cleco. The aft holes in the ribs and tank skins line up perfect it?s when you start working your way down toward the leading edge where things start getting hard to fit. I made sure that all my ribs had right angle flanges and flutes where needed to make flat. Is there a trick to assembling the tanks? Is there a certain order items are assembled to make everything line up and fit.
