I'm to the point of initial assembly of my right wing on my 9A, fitting the main ribs for matchdrilling to the front and rear spar. When I clecoed in the main ribs, they match up perfectly on the bottom of the front spar, but on the top of the front spar there is an angled gap that is consistent on every rib for the length of the spar. It looks just like the spar flange has been under-bent, or the ribs are too wide and are spreading the top spar flange away slightly. I can force the flange in to fit by hand, but it takes quite a bit of force and I'm not quite kosher with this being correct. Can any one here provide me some guidance? All the ribs have been straightened, deburred, and fluted and look beautiful when laid on a flat surface.
This first image is the top flange of the front spar, outboard end.
This image is the bottom flange, outboard end - it mates up just fine.
