First build project--having fun so far--but still in the early learning stages.
Specifically, I'll be starting soon on my rudder trailing edge. Double countersinking is done in the TE wedge, double sided tape is standing by, and everything is dimpled and ready to go as soon as I finish attaching the stiffeners and shear clips to the skins.
I've been studying ahead to the trailing edge instructions and have seen some warnings about the difficulty of achieving truly straight TE's. Also seen some posts about twists occurring in the TE as rivets are final set in the double flush fashion required. Some posts have referred to setting half of the TE rivets in one direction and half in the other to minimize twist.
OK, finally the question: Since the direction of the shop head is "builder's choice" on a rudder, has anyone tried alternating rivet direction with every other rivet in the TE? If every other rivet had the shop head on the same side, alternating with manufactured heads would that not tend to offset twisting tendency? Would it look lousy as a finished product?
Maybe I'm overthinking it--wouldn't be the first time--but just curious.
