A whole day in the workshop. First Sabine helped buck the leading edge rib to spar rivets. Some are really tough and I replaced some with pop rivets (which is allowed by Vans). On the picture a rib with plain and pop rivets.



Then I installed the fuel tanks, they came on and of a few time for minor adjusments. They are only temporarly bolted on as I will prime the parts that are not done (rear baffle and outside ribs).



The next time I take the fuel tanks off, I'll have to arrange the little "pillowing" shown on the picture. For this, I'll drill out the rivet on the leading edge side and shim the skin a little. I also have to sand the left fuel tank skin where it meets the leading edge skin as there is not enough play.



Then I installed the pitot line, it has some bends so as not to interfere with the fuel tank bolts.



And to finish, I clecoed the upper skins.
