F11-01 Fuselage Box Assembly.
I made a strap duplicator to locate 6 holes (3 ea side) where the lower skin and aft lower skin overlap. I drilled #40 holes and up drilled to #30. That completed the holes joining the lower skin and aft lower skin.

I drilled the pilot holes through the splice places and upper and lower longerons.

I started to locate, pilot drill and celco the F16-02 Forward Tunnel Zee.
