Rivetted the rudder trailing edge. The deviation from the straight line turned out to be less than 0.1", albeit some waviness remained. Used too much glue. Unfortunately, during rivetting, the aft edge of the skins developed a slight turn to the left (in flight direction). Probabely due to rivetting with the large flush rivet set, therefore bending the skin. Could also due to the slight chordwise difference in distance of the holes of both skins. Fortunately, the slight bend to the right will act as a trim to deflect the rudder to the right, counteracting the asymetric thrust of the propeller during low speed, high power configuration. We'll see...
Matchdrilled the left elevator skin to the main and trim spar and the root rib.
