I cleco'd the left elevator horn to root rib and spar and, just to see how it would line up with the skin, cleco'd the spar to the outside of the skin. There's quite a bit of divergence from the expected alignment of the rib and skin. The rib is (as per instructions) riveted to the spar but I suspect I might have increased the radius of the riveted rib flange during the "slight bending" to allow the riveting. Since the rib is now riveted to the spar, how can I put the squeeze on that acute angle on the rib flange? Or is there something else I'm totally missing? Thank you for your replies.
