More riveting. The toughest part to reach is the most aft rivets that attach skin to aft spar. I can't really use the rivet gage to assess whether those rivets are set correctly. Only by feel am I able to assess whether they need to be driven more or are set adequately. If I had followed the plans, clecoing from the aft spar fwd to the J stiffeners, I would not have been able to reach all the way to the most aft rivets. I could only clecoe halfway from the aft spar to the J stiffeners to allow sufficient flex in the skin to reach in that far. I checked torque on the Z track bolts that hold the fuel tank in place. Also I ran all wire harnesses through the wing and placed extra conduit for future runs before placing the skins on.
