Brief Description: Cutting the access panel holes, part 1
Using the poster board templates, I measured 2.5" distance lines away from, and parallel with, the forward and bottom rivet lines on the skin. These constituted the edge of the access panel holes.
I measured and marked the center of the corner circles (2" diameter), then drilled pilot holes there in #30. I then drilled the holes out with a 2" hole cutter.
