Riveted the main ribs to the front HS spar. Sorry, forgot the picture.
Riveted the middle rib tip (HS-707) to the left skin. It was very easy. I set the rivet gun to so soft it wouldn’t drive the rivet and then opened the valve two turns. Three would probably have been better, but I wasn’t in any hurry and didn’t want to chance denting the skin.
It’s a little hard to tell what this is, but it is the skin wrapped around the center rib tip.
That’s enough! Going to bed.
