When I first started a number of riveting troubles were caused by the parts not being clamped or secured very well. If the part is wobbling around and you are trying to support it, use the bucking bar and rivet gun... well, it doesn't work too well. If the parts are clamped and secured, you can see how everything lines up and you can get the bucking bar square to the rivet, then things go a lot easier.
