I did my first backriveting tonight. It's simple and gives great results! ... as long as the back rivet plate is under the gun. I was riveting the 2nd to the bottom stiffner on one of my rudder skins and the plate wasn't under the gun. It dented the skin a little bit and made a bulge on the outside of the skin. Do I leave it alone or fix it? Will I develop a skin crack there? I'd like to make it flush again but I'm afraid I'll make it worse. It's alot of work to replace it, but I'd rather do that than have problems later on if that's what I need to do. Thanks! (I tried taking pictures, but none of them showed the mistake very well.)
