I used the close proximity tool to install the LP4-4 rivets connecting the main ribs to the spar. After attaching the main ribs I drilled and riveted the rear sub-spar to the ribs. I then clecoed and riveted all of the nose ribs to the main spar along with the forward sub-spar. The right wing skeleton is now complete and I can move on to the next step – build the stall warning device.
