Brief Description: Install the leading edge rib and joint strip
After my father and James left I decided to finish the installation of the interface rib, which also holds the strip of aluminum that joins the fuel tank to the leading edge. I basically followed the instructions and it all went quite well, I have 11/16 of the joint strip protruding as requied by the instructions. Back drilling the rib to the main spar was a pain because of the restriction imposed by the rear rib which is already riveted in place, I ended up using my angle drill and a long drill bit to drill the #30 holes.
