I don't really want to post this, but I've got to know how serious this is: I finished skinning my vertical stabilizer a couple of days ago, and following the directions clecoed everything, made sure the holes aligned and that the leading flanges on the ribs were properly radiused so as not to deform the skins. Aside from the tight fit of the skin on the skeleton everything went smoothly. Yesterday I was looking it over one more time and I noticed a small deformity around the leading starboard rivet on the VS-1205 rib. I looked inside and found that the flange had deflected slightly away from the skin so that it wasn't fully in contact with the skin. I think there had been enough play in the clecos that when I put that rivet in it wasn't obvious at the time. Anyway, there's a small ridge on the skin where the edge of the rib is pushing out, and the skin around the rivet is recessed slightly as the rivet is pulling it in towards the bent flange. I dread removing 126 or more rivets, but I'll do it if I need to. I've asked Van's for an engineering opinion, but I'd welcome your thoughts as well. Seems this has been a bad week for my build after starting out strong. I've attached a few images. It was hard to capture the surface deformity and the shadows make it look worse than it seems in real life.
