RE: Junkers JU-52 How to corrigated metal
I would suggest you find your corrugation material that you plan to use (whatever it might be) and build around its scale rather than the other way around. Corrugation is made by running a material between the mesh of two gears. The cardboard corrugation variety can be purchased cheap through a cardboard making Co. such as Weyerhauser or found in a craft store or box and packing supply stores.
