Brief Description:  Rebuilt aileron--complete

Finished riveting trailing edge of rebuilt right aileron. Drilled out every other hole on the Al angle to 9/16" so back rivet set had access to the rivet hole. Clecoed the modified Al angle to the aft skins/AEX wedge and set -3.5 rivets half way with the big bucking bar on the top skin. Then unclecoed and removed the Al angle, taped rivets into remaining holes, and back-riveting against the 1/2" steel plate set into a piece of 1/2" MDF. Turned over the aileron and set the rivets all the way with a mushroom set against the top skin and steel plate below.

Image 1 is the right aileron bolted into position on the right wing. Image 2 attempts to show the pretty darn straight trailing edge. No Proseal used this time. A touch less weight in the right wing, but not enough less to affect previous W&B much, or offset the roll A/P serv's weight in the right wing. Image 3 is a view from underneath, showing new pink nail polish (cheaper than Torq-Seal lacquer!) on the inboard pivot. On initially torquing up the pivot bolts, the aileron wasn't completely free to fall from neutral to down-aileron position. The fender washer against the spherical bearing was in contact with the bearing's bracket. I shortened the spacer tube so a thin washer could be inserted between the fender washer and the spherical bearing. (The thin washer diameter is small enough that it doesn't bear on the bracket.) Success: a (nearly) friction-free aileron movement!
