I had been buzy all summer on an other house project and I am resuming working on the airplane today.
Last spring when I was drilling the first row attach bolt holes of the bottom of the right tank, the holes were drilled close to the edge. I called Vans and the best fix for this was to add a doubler, 0,032" . I do not know why I did not see it before the holes were drilled but it happened. I still have to drill additional rivet holes between each bolt holes.
