Rudder 07-03 to 07-05

Riveted the ribs, reinforcement plates and nut plates to the rudder spar after priming all the parts yesterday.  Awkward rivets again inside the spar flanges.  Rivets that I hit with the assistance of an extra pair of hands came out much better.  The squeezer tended to pull the AN470-4s at a bit of an angle no matter how I tried to line up the yoke.  Priming the inside of the skins next.
