skins. It has been designed to accommodate the larger skins used in the

Warren,
I had the same problem, I got all the ribs riveted to the main spar and when
I looked under at them I almost sh....... well you know. This was the right
wing too, I had already done the left wing and for some (luck of the draw, I
guess) reason they all turned out OK. Anyway, I ended up drilling out over
18 rivets! I read the advise on a lot of sights and then found that duct
taping up my rivet set and paying attention to the factory head more did the
trick. Live an learn I guess it is all part of the journey.
