You can get nice curves in sheet metal by pounding it with a bag filled with metal spheres, like large ball bearings.
Sort of like hand-grinding a telescope mirror, or polishing stuff. The dents average out.
Not a good way to build anything with close tolerances, but a way to manually build a thing.
