Gordon C came to the hangar for some riveting - L wing Top Skin outbd.
Started on the inboard front corner and worked diagnonally and out. Wasnt' a perfect day, hit 111 Degs F before we quit. Had a few imperfect rivets but made it throudh 5 or the 7 ribs and partials.
The last three ribs are reachable from the end and I may be able to work through those after some rest and cooling off.
