Fuselage side skin side plate countersinking

While building the forward fuselage ribs/bottom skins, I realized the center section side plates would be quite hard to machine-countersink at the expected time (middle of section 29) with how close they are to the center section bulkhead assemblies, so I clecoed them to the skins, match-drilled and machine-countersunk them at that time:

Just a small step to save time later.

Time lapse:

Total fuselage side skin rivets: 0
Total fuselage side skin time: 10.7h
