I made the F-796C & D Spacers as shown on DWG 38. I then drilled the top 3/32” hole in the spacers at the dimensions shown, but left the other holes undrilled for the time being.
I made the F-796B reinforcement angle (DWG 38) and drilled only the top hole. I then drilled the 3/16” hole to #30 for now.
I studied drawing 38, Detail F to better understand the fit of the spacers and angle with the bulkhead flange and longerons.
I put a centerline on the outboard face of the F-796B angle and clecoed it on the inside of the longerons using the upper pilot hole drilled in the angle. When the centerline on the angle was visible through the lowest hole in the side skin, I drilled and clecoed it to the fuselage. I match-drilled the remaining holes through the angle using the holes in the skin as guides. I drilled as straight as possible so as to minimize any hole position error due to the gap between the skin and angle.
Time: 4 hours.
