This is the original classic paper that started the fold-forming scene. Fold-forming or foldforming is a system of sheet metal forming which emphasizes forming using the metals characteristics. Forms are derived from the natural plasticity, ductility and elasticity of the metal. The system is internationally recognized as a new approach to working metal. It is extremely efficient and rapid. Tools are simple: fingers, hands, anvil hammers, mallets, and rolling mills. The paper has a theoretical introduction and step-by-step recipes for quickly working sheet metal. 49 pages, over 70 B/W line drawings. This was the precursor to the full color 2008 book "Foldforming" by Lewton-Brain.
