Hello my drive into work is about an hour, which gives me far more time to think than I probably should have. Diving in this morning I was thinking about differnt ways that might be possible to build the fuselage of an RV. One idea was welding the fuselage skins to the longerons. I figure that there would be a problem due to vibration causing cracks in the welds, but what do I know. Any comments on the idea of welding?
