Started the right bottom outboard wing skin - 3 hours

I finally managed to get back into riveting. The first step was that I clecoed the entire wing skin onto the wing to ensure straightness. Once I was happy with how it all sat. I took out the clecos and set the inboard line of rivets. Then I re-clecoed the skin down in its entirety and set the complete bay through the most outboard access hole.
 
 
 I reached the point on the rear spar where I could not use the bucking bar where the aileron stiffener was. I used MK-319 rivets instead.
