How to make aluminum bend with a concave shape?
Slap bracelets are made of spring steel, not aluminumYou would need a metal roller with a custom made wheel to put the concave bend into the spring steelThis is best done in a mass production environment, since the tooling is quite expensive.
yes do use foil thats the easiest.try to trase something with the same shape of a boat,use your imagination!
I am not sure this will help your cause or not but check into the Carbon fiber sceneI have built a couple of airplanes from this materialIt will hold just about any shape you put to itThe weight to strenght ratio is outstanding! You can get this product at hobby shops and auto body shops as well as aircraft repair supply vendorsIt used to be very $$$, however over the last couple of years the price has come down substantiallyThe only drawback here is it is non-metallic and tetravalentWould your instructor cut you some slack for being resouceful and thinking outside of the confined realm of given thought?
