Boring pictures that look the same as yesterday, but there's progress, I promise. I rolled up the inboard wing and started riveting the upper 1/3.
The rivets around the flap brackets are a real pain to set well. I don't have a rivet set for the gun that is long enough to get the gun out of the way of the bracket, meaning I can't get the set directly over the rivet (and flat). I ended up using my small mushroom set duct taped to the gun so I didn't have to use the spring. That gave me a tiny bit more room - not ideal, but just barely good enough. For the most part it worked okay, but one side of the middle bracket was a bear and ended up with some skin "character."
