Prime gussets F757S and canopy rails F721A and B. Rivet rails and gusset to the longerons. Rivet the armrests (another item left undone previously).
I just looked at the time and it's hard to believe that those few items took all day. There was a lot of thinking time today. I bet I colecoed and uncolecoed the side rails 4 or 5 times before they actually got rivets. Lots of fit and checking before things get permanent.
