The first rivet for the nose rib is quite difficult to get to lie flat against the skin. Not possible to do with only one person. So my wife held the nose rib against the skin while I bucked that first rivet. I found it much easier to only have the first cleco (behind the first hole) in place, to help keep the rib flange close to the skin.
Since the first rivet in the center nose rib was difficult, I also put in the first 2 rivets of the end rib. It doesn't affect how the rest of the assembly goes together.
Riveted the top and bottom of the center ribs to the skin, and riveted the inboard and outboard ribs to the forward spar.
Set up the clecos and rivets (with rivet tape) so I can rivet the skin tomorrow.
