Hey everyone, Do you think it would be possible to make a copper bike? I think copper is a pretty soft metal, but is it softer than some of the finer steels? Anyway, I was thinking about looking into this, but I don't really know where to start. I can to calculations, probably, to figure out wall thickness and tube diameter if I can get all the metal properties. I just don't want to do that until I know it is worth it. Also, how would you welt this? Anyone worked with copper before? Brass is an option, but I don't know if would patena.
