Laid out hole pattern for outside 2 holes on 405 rib flange. Used Whitney punch to punch the holes. Clecoed 405 rib to skin and 602 spar. Pulled up tight with long clamp and drilled 405, 702 and 810/814 holes with angle drill. Took apart and cleaned out chips. Clecoed 405 back to skin and clamped again. Drilled skin to 702 spar—outboard to inboard. Punched holes in 404 flange. Clamped 405 to skin and drilled 404 to 702 and 405 rib using right angle drill. Checked all edge distance. All ok except joint of 801 skin to 602 spar and 405 rib. Same issue as on the left half. Per Van’s, there is no way to get minimum edge distance here. They said take what you get, rivet and move on.
