Brief Description: Positioned skeleton in skins, riveted front HS spa
After determining I had my swivel-nose pop rivet tool, I installed the next-to-last outboard in-spar ribs to the skeleton using AN470 AD4 rivets instead of the LP4-3 rivets called for in the manual (the only reason to delay riveting these ribs is so the nose ribs can be riveted with a normal pop rivet puller; with the swivel-nose tool I could install the rivets in the nose ribs even with the inspar rib in place. See Image 1). The skeleton was positioned in the left and right skins and clecoed to the nose ribs. Then, except for the inboard ribs, the nose ribs were riveted to the spar followed by outboard in-spar ribs.
Then the skins were clecoed to the front spar and riveted according to the callouts, except for the rivets at the inboard and tip ribs (which will be squeezed later). Once the spar was riveted, the top skins were clecoed up to the stringers (6 rivets for the outboard ribs) in preparation for riveting the skins to the ribs and stringers. (The bottom skin will be clecoed and riveted after the top is done. Then the rest of the rivets will be set and, finally, the rear spar added and riveted. I find that doing the top skin makes a nicer appearance on the more visible side of the HS even though the bottom side is still quite nice.)
