Today I finished riveting the upper skin on the right wing. I riveted the wing walk doubler using the flat head rivets at the leading edge as indicated. All went well.
I turned the wing over and clecoed the trailing edge rib to the rear spar. I also clecoed a section of the bottom of the wing tip in place. It is ready to be riveted to the wing. I will turn the wing back over and begin installing the upper wing tip skins.
