Brief Description: Lay out nose rivet pitch on right spar
1. Use edge marker tool to draw rivet lines on the nose rib L-angles at 9-mm from the front edge.
2. On each angle, mark the location of the end rivets, 10-mm from the ends, except on the long L-angle on the spar tip, where I put the end marks 12-mm from the end.
3. Use the rivet fan to evenly space 5 rivets on the short L-angles, 6 rivets on the long L-angles, and 7 rivets on the spar tip L-angle. I chose to use 7 rivets on the spar tip l-angle, because it is significantly longer than the other L-angles. See Figs. 1-3.
