Brief Description: Wing Root Fairing 4: Mark 3/16 clearance
I enlarged the holes to #19. I'll be dimpling and countersinking these holes for flush #8 screws.
The drawing says the gap in between the fairing and the fuselage needs to be a minimum of 3/16 and maximum of 1/4. This must be for the rubber stripping that will go in here later.
So I found a piece of 3/16 aluminum and used it as a spacer to mark the fairing 3/16 from the side of the fuselage.
