On Sunday Dusan gave me a hand to assemble the tank so that we could sit it in place to back drill the joint plate between the two nose skins. Getting the ribs clecoed in place was a real job and a half and occupied most of our time, the actual drilling was a breeze and turned out really well, the butt joint between the skins is perfect.
