Seeing how my rivet selection was limited, I ordered a few varieties
from Aircraft Spruce as well as the AN470AD5 rivets that I need to complete the
HS front spar. I decided to use scrap to dial in the pneumatic squeezer and
made short work of completing the outstanding rivets. I decided to replace one
of the AD4 rivets with an AD5 rivet that was opposite the needed AD5 rivet
purely for symmetry. Not needed, but it looks better.
