Anyone else have this same problem? I was back-riveting the stiffeners onto my elevator skins, and they -always- bent over a little bit. I didn't have this problem at all with the rudder skin/stiffeners, but then of course that skin was thinner and rivets shorter. That worked out very well.
I tried removing a few of the worst ones, and basically ended up with an uglier hole. I drilled it to #30 and used a -4 rivet in there instead (next size up method).
The elevator was a different story. They just never could go in without leaning or "smearing?" over to the side. Some reason it always leaned toward the leading edge. I was using the backing plate and the spring loaded rivet bit too.
I then tried reversing and simply clekoing the stiffeners with every other hole, and riveting with the "red rubber mushroom" riveter attachment on the skin side and the buck bar on the inside. That all worked out very nicely on the shop side and the factory head worked flush too. I did have a few to remove and re-do, but they turned out pretty well.
Is there any drawback to have done it this way? It seems that my flush heads are in pretty well, and not sure if I would have any more indentation around the skin if I did it correctly with the back-rivet way.
Anyway, just looking for some reassurance that diverting from the plans isn't a problem.
