I drilled additional holes in the hinges that will rivet to the wingtip so that I can form some epoxy/flox “rivets” between the aluminum rivets.
I countersunk the right wingtip and then riveted the hinges on. You can see the epoxy/flox “rivets” here. Afterward, I spent a little time cleaning out all of the epoxy that squeezed out around the hinge eyes so that it won’t interfere with installing the hinge on the wing.
