Over the course of a week, I applied the flaperon skins to the ribs. This went smoothly. The drilling I had done on the counterbalance pipe gave me pause. The pre-drilling punching that I had done to ensure that the drill bit didn't "walk" out of the proper spot created the equivalent of a machine countersink and it looks like it when the skins are riveted at that point. I hope the photo will show this. Other than that the only challenge was again, the match-drilling through the skin into the noseribs. The lesson I learned here was to recognize when I'm tired and stop for the day. The result of not stopping was poor technique. I didn't start the match-drilling with a #40 and the result was elongated holes. I judged the holes to be outside the limits of tolerance and so made another trip to Van's to pick up another nose skin and do over. The do-over went well and the flaperons are now complete. Tomorrow, I will start on the fuselage.
