Empennage

Aft Fuselage (2.5 hrs )

LH Side Skin...repeat.  1st "break" edges with edge forming tool (rollers) , then deburr edges, then deburr all holes.   Dimple #27 (6 holes), #30 holes (few exceptions), and all #40 holes.   But only partly done since beautiful day @ 75, clear sky with low humidity = perfect to take Harley for cruise in afternoon.


Above pic shows inside curved skin, requiring reduced diameter female die.  Still leaves marks, but no "dings".  Didn't get to polished finish on die surface.  Requires continuously monitoring alignment so die "nests" in the curve with sides modified, and holding skin at appropriate angle.
