I'm at the stage where I need to rivet the F-1075 aft top skin to the F-1009 and F-1008 frames and the F-1073 side skins and the F-1032 longerons. Before I do this I want to DOUBLE check that the aft top skin gets riveted BETWEEN the side skins and the longerons. It seems more logical to rivet it OVER the side skins. Like a shingle overlaps another shingle. Water and all that..... What have y'all done? Thanks, Dan
