Again tonight it felt like a productive one because I got the remaining parts primed and riveted the right aft fuselage structure. All of the top longeron rivets get installed later per the plans. Luckily I didn't have any rivets where the mandrels pullled "proud". I have the earlier version of the Cherry rivets which didn't have the problem which many new kit owners are having.
I still have to countersink the rudder stop plate and install the CCC-44 rivets there to finish up this side so that I can move on to assembling the LT structure.
