Rivetted HS front spars, front spar doubler and attach angles. Rivetted HS rear spars, rear spar doubler and hinge brackets. Put left HS skin in fixture and rivetted mid front rib. On last rivet the shop head formed between the skin and the rib. Had to drill out the first rivet in the aircraft. Sure sign that we should call it a day.
Next: Rivet HS left skin to ribs and spars.
EDIT: The drilled out rivet was more stubborn than thought, see 19.02.2011
