When Matt woke up this morning, it didn't take us long to rivet the top main skins to the right wing. Riveting is very easy and goes very quickly if you have a good helper. It's all the prep work that takes the time. All of the rivets along the inboard rib and rear spar can be squeezed so we left these for me to do later.
