Brief Description: Finished drilling the last top skin.
Today I finished drilling the last top right skin. It was a little different because I had already drilled some holes in the ribs. I first removed the clecos from the bottom of the skin. I then match-drilled a strip of aluminum to the front most holes of the nose ribs. This was to make sure the ribs stayed alligned while I was back drilling the top of the nose ribs. Once the strip was clecoed into place, it was pretty simple to back drill the last of the nose ribs.
