Wing fairing work: 3 hours

  • Finished drilling right wing for wing fairing plate nuts
  • Deburred all holes for right wing fairing
  • Edge finished and edge rolled wing fairing and fuselage to wing skin
  • Used pneumatic squeezer to flatten some fluting for better platenut mounting
  • Used pneumatic squeezer to dimple wing farings and fuselage skin for #8 screws
  • I ground down the female dimple die to clear the wing rib and fuel tank edges then dimpled all of both wing roots
  • I countersunk the wing for #8 screws in the area of the wing walk doubler - I used a new single flute countersink from Cleaveland Tool - it worked great - no chattering 

Countersinks turned out great - used the dimpled scrap to check fit

Dimpled fuselage to wing skin:
