Had an idea, metal like brass and copper can be beaten into shape from a sheet. This can be done free hand using a bag of rice as base surface. Then to finish off it is help full to have a wooden half mould. the two halves can then be hinged and bolted together.
brass sheets are quite cheap and easily available you will also need a round headed hammer.
I.ve made clasic car parts this way in the past and im sure this can be done for chashity but ill let you know how it goes.
