The F-7101 is a thick plate to beef up this corner of the forward fuselage. It fits snuggly inside the longerons and bulkheads. I rounded and smoothed the inside edge to enhance fit. Then I clamped and driled it through the stiffener.
I did NOT drill to to the bottom longeron yet. I guess this will happen later.
I also drilled the forward bulkhead to the skin at this point.
