Wing ribs complete

Riveted the forward flanges of all the ribs to the spar with the rivet gun. My riveting seems to be getting better… Didn’t have to drill any out. I set the pressure at the compressor to 75psi for the -4 rivets. This seemed to work really well. I had tried a lower pressure in the past and the manufactured head would get all beat up. At the lower pressure, I had to hit the rivet so many times that I think it was getting work hardened.

I also finished installing the AN3 hardware and torquing to spec. Kinda sorta starting to look like wings…

Picked all the parts (including the service bulletin kit) for the rear spar.
