Went ahead and began riveting the first rudder components together. Riveted the bottom rib together and then attached the rudder horn to it. Then riveted the doublers to the the spar and attached nutplates to the rudder horn, and both doublers . Finally I riveted the stiffners to the right skin before calling it a night. Had to grind a little flat spot onto my back-set's plastic collar as it wasn't seating properly on the rivets because of the stiffner flange. The mod helped as the rivets turned out fine.
