I am attaching the 808PP doubler to the 803PP rear spar. After counter-sinking the 808 doubler I clecoed it to the 803PP spar to check the fit. It appears the doubler is standing a few thousandths above the spar. Notice the lack of a gap between the right lightening hole and the spar and the presence of a gap on the left hole.
I'm afraid to countersink any deeper before I get some advice. The countersink is already slightly deeper than the rivet itself. I expected that since it has to accept the dimpled spar. But I don't want to go any deeper until I check with the pros.
