I would like to make X75 Hurricane-like sheet metal for my cafe (Pic). I was going to model it in CAD, cut it into manageable sized pieces (I want exposed rivets anyway) then section my models and make wood molds/templates for the maybe 3 or 4 pieces on each side and start hammering aluminum down, potentially heating it for the smaller radius curves. If anyone knows anything about beating on aluminum does this sound like a good way to do it? I'm concerned about using softer aluminum and having hammer divets all over it that I can't get out. Any particular kind of aluminum I should be looking for?
