Drilled the newly fabricated F-710B to the F-710 bulkhead.
Removed the old F-711D attach angle, then set two skin rivets, one on each side just forward of the F-711 uprights that had been inaccessible with the angle in place (photo 1). Fabricated a new F-711D (out of 3/4x3/4x1/8 angle this time), and drilled it to the F-711 bulkhead (photo 2).
Prepped and primed both new attach angles (photo 3).
