Brief Description: Drill nose rib anges for left spar NR#2, and NR#1
Drill nose rib anges for left spar NR#2, and NR#1
1. Drilled holes, 3/32”, 1/8”, #20 through angles to attach NR#2 to angles. See Fig. 2. drilled holes 3/32”, 1/8”, #20 through the wing root doubler to attach angles for NR#1 to spar. I used a piece of .040 behind the wing root doubler to protect the spar web from the drill when it penetrated the doubler. That worked well.
