Spent most of the day riveting the rudder together.
The first stiffener riveted on:

First half of the riveters on. When I primered the rudder skin, I fogged it on in the whole skin, but made sure the contact area where the stiffeners attached were completely covered. I plan on going back and touching up the rest of the fogged on areas.
R-713 riveted to R-703. The last three rivets that attach R-713 to R-703 are left out, since the rudder skin will also need to attach here.
