OK now for some special stuff, made the flop tube mount into the tank attach angle, finished all the anti-hang up guides, riveted these in place, made sure it was all working as it should be. Sealed and riveted on the nose reinforcing plates onto the end ribs alon with the flop tube. Thought I would do this before I attached the ribs to the tank, as it is quite messy and I wanted too make sure it was sealed and riveted properly. I will leave these ribs for a wek so they are nice and dry and sealed.
