I rivited the rudder skeleton together. I managed to get solid rivets everywhere. I did some shaping on the counterbalance weight so that it would clear the rivet shop heads. I torqued the weight on. I riveted the counterbalance skin. I'm ready to cleco the skins on however I accidentally primed the trailing edged where the proseal will go. I knew I did not want that primed but I forgot to mask it. I'll take it off with some MEK in the morning.
