Removed angle (F703-B) from instrument panel (F-703) to deburr and prep for assembly. Need to get it ready to ship to Advanced Avionics for panel build. Drawing says to use 426-6 rivets, but they seem way too long. Gonna try -5s and see how it goes. Also sanded down bad paint on oil door frame and primed with the standard grey rattle can paint from Napa.
