I worked pretty much all day on riveting the frame of the rudder together and then riveting the skin to the spar and the ribs. This was fun and all went together nicely. Then per the instructions, I epoxied the trailing edge together (JB Weld) and clecoed it to a angle so that it would be perfectly straight when it set. All that is left is to rivet the trailing edge in a few days after the epoxy has really cured and roll the leading edge.
