I worked on two projects today intended to enhance my metal skills in building the RV aircraft. My strength is that I understand the directions and diagrams, but my weakness is flush riveting in areas that are difficult to get a bucking bar into proper position. I'll need to acquire a pneumatic squeezer to help, but by and large, I'll have to take time to get bucking bars that fit odd places, and do my best not to mess up the metal around the flush rivet head. I'll offer photos when I get the camera.
