For the wingtip rib that runs spanwise, the plans have you bond it first and then rivet it with 3/32 rivets. These rivets will have to be set with a rivet gun, because it's too deep for a squeezer to reach. I'm not crazy about smashing that thin fiberglass tip with a rivet gun, so I'm thinking about just relying on the epoxy to hold it in place. I would think with a sufficient amount of epoxy this would be more than strong enough. Thoughts?
