Stopped by hangar again to complete the next step in the instructions. Also dropped off the new E-703 pieces which I'll use to make little end-ribs for the Trim Tab and the Edge of the Elevator. Need to prep and prime those pieces. Might first cut them to size though.
Tonight I just used the PneumaticSqueezer to install four rivets. Piece of cake. Trying to check off one step at a time. Tomorrow even more rivets. Hopefully it will be more challenging.
