I had to drill out the left aft 9 rivets after riveting the top skin. I didn't break the edge enough and I didn't like the fit. I used the Averytools edge roller to increase the break. For the other edges I used the Cleaveland tool. After I placed the tailcone into the sun my son (wiseguy ;-) ) pointed out to me that I forgot to place one rivet (bright spot, image 3).
