I need to fill some tooling holes on my fuel tank end ribs. Since it's not structural, I'm planning to use AN470-A-6 rivets, which apparently are the soft aluminum rivets. Does anyone know if a standard squeezer will set these "soft" size 6 rivets? I'd like to proseal and rivet my end ribs in while waiting for the rivets to arrive. However, if I can't squeeze those rivets, then I'm going to have to buck them. If that's the case, I'd rather back rivet them without having the ribs installed.
