On my RV8 I’m am having so much trouble with this trim tab, I want to pull my hair out. I’m getting through, just slowing myself down and taking one step at a time. My problem now is when riveting the hinge to the trim tab I use the pneumatic rivet gun with flat head and bucking bar. By doing this it knocks the hinge wire holders out of alignment and in some cases it squished them to the point where I couldn’t fit the hinge wire into the holes. With patience and time I got the tab side done and forced the wire through the hinge with a hammer. Now I have to rivet the elevator side of the hinge flange. What can I use that won’t alter the alignment of the hinges and wire?
