Today I fabricated the joggle supports for the left of the two floor panels. I believe I'm ready to drill these to the lower longerons on both sides of the fuselage, but I need a way to install nutplates on the underside of the lower longeron flange. It's really close to the bottom skin, so there's little to no bucking access. I'll do some research to see if I can find some 3/32 pop rivets that'll work.
