Used snips to make all the cuts. Doh! Should have peeled the blue vinyl off before I cut them.

Then cleaned them up on the scotch bright wheel, scuffed the mating surfaces and dimpled.

I ordered plexi bits and a zero flute countersink so that I can fabricate the landing light lenses. While I’m waiting for those to show up, I started on the tanks.

Fluted and straightened the tank ribs yesterday. Final drilled all the #40 and #30 holes in all the ribs tonight.

Located and drilled the 3/4″ hole specified in the plans.
