Lined up rear edge of nose skin with back flange of spar. Lined up rivet lines with actual nose rib locations. Drilled and clecoed nose skin to spar. Marked nose rib rivet locations. Instructions say to put first rivet 30mm from spar rivet line but that doesn't allow proper edge distance on nose rib. Went with 37mm. Checked using nose rib from right wing to ensure rivets would miss crimped areas and had proper edge distances.
