Drilled out top nose skin and top main spar to final size. I will need to order more A5 rivets so I can drill out rear top skin. It definitely takes 2 people to line up the rivet lines for the top nose skins. Since the bottom nose skin is drilled out and clecoed, moving the top of the nose ribs requires another person to move rivet line and hold it while another person does the drilling. I am learning alot about the wing construcion that I will be able to use on the right wing which will hopefully make the right wing easier and quicker to assemble.
