Well I'm at that point where I'm trying to figure out how to rivet those final few rivets on the bottom rudder skin-to-rib. The plans say it is acceptable to use pull rivets here, but most of the RVs I see seem to have used flush rivets. How are you guys doing this? I tried to make a thin bucking bar, but when I ground the metal thin enough to fit in that tight space, it bent when I bucked it.
