I am almost wrapping up the empenage kit and put the fiberglass tip on the rudder this evening to see how it fit. Had to shave some off to get it to drop into the rib down to the seating line. When I push it over to the one side, there is a 1/4 inch gap on the other. How do you pop rivet this thing on when it is squeezed together like this? Is there a trick to spreading it open enough for rivets to work? Does a person even put them on permanently now or wait till later? I don't know much about fiberglassing but I guess I will shortly. Any pointers on how to attach them and when the best time to do it will be appreciated.
