Brief Description: Wing Alignment 6: Drilling Wing to Fuselage skin
Plans call for back drilling the holes on the bottom wing to mid-fuselage.
So I got under the fuselage on my crawler. Add some lights. First thing I did was draw straight lines on the mid-fuselage bottom skin which were extensions from the lines drawn on the wing bottom skin earlier.
Then I measured 3 inches from the marks I had made on each line, and made a new mark on the mid-fuselage bottom skin, which should be over the top of the hole underneath.
I drilled all the holes first with #40. then #30, and finally with #19 for a number 8 screw. The holes hit the previous holes pretty well. I was able to see this with a mirror, but no photo.
