For this wing, I had to do the riveting out of order from the previous wing. The pitot mast needs to be installed, and there's a complex dance of which surfaces go where, with lots of overlapping. You can't just put the pitot in from behind. You need to have the bottome skin un-riveted or clecoed, so you can warp the skin while simultaneously positioning the mast.
So I riveted the upper (rear spar) rivets first, because there would be no way to reach them once the pitot mast was installed. Then I went down to the pitot mast and set all those rivets.
Now I can go back to all the other rivets in that area, which I can reach on my own.
Most of this row I could reach. My wife helped with 5.
Lots of different sized rivets around the pitot mast
