Corner Skins, riveted in place
close up of corner skins
Bottom of Fuselage
Bottom of fuselage, showing the exposed rib structure. This is a “before” shot, to be compared with the placement of the bottom skin (on the table in the right side of the picture.)
Not shown in any pictures are the preparation steps of the bottom skin doublers (internal and external.) Those are triangular shapes that are almost (but not quite!) the same. I made ‘toe tags’ to keep them all straight, as I had previously done with the corner skins.
