This evening I final drilled the holes in the tailcone using a #27 bit. I used a 6x32 screw to hold a nutplate centered on each hole. I drilled #40 holes through the ears of the nutplates. I then deburred all of the holes. I clecoed a nutplate to each set of holes and used the 3/32 dimple die to dimple the tailcone and the nutplates at the same time. I then riveted the nutplates to the inside of the tailcone.
All 12-nutplates have been riveted in place. I will need to use the modified #27 drill bit and final drill the holes in the fiberglass tailcone fairing.
