Only spent a few hours on the tanks today, but still made some good progress. First I finished deburring the tank baffles, I clamped them to the table to better reach the “inside” flangeĀ rivet holes…

Then I deburred the right tank skin edges and rivet holes.

I also scuffed up the skin where it will seal against the ribs and stiffeners. For thisĀ I used my Roloc scotch wheel and a piece off wood as guide.

Finally I dimpled all the rivet and screw holes on the right tank skin.
