Today I am working on installing the nut plates in the angles I have made. The first step was to open up the holes for the screws to #30. I then removed the angles from the wing skin. In order to install the nut plates I needed a spacer made from 0.062 in. 6061-T6 sheet. I cut strips 5/16 in. wide and then proceeded to mark them for the holes for the nut plates. The strips will be countersunk on one side to allow the rivets and the screws to be flush on the outside.
