After having rivetted the stiffeners to the skin, first assembly of the skins and skeletton. The all the holes get match drilled.



Then everything gets undone, the holes deburred and dimpled. The skeleton was then sanded in preparation for priming. I finished the afternoon by countersinking the angle that finishes the trailing edge. To do this a built a little jig on my drillpress so that the upper face of the angle stays horizontal while drilling.
