Next question... I would rather just make my own hammer attachments. Seems how I know little about plastics, what should I use for the hammer ends? I'll guess some form of nylon?
It depends on what you are forming. Soft aluminum would require a softer, but stiff plastic, while steel would be more like delrin or at the extreme end something like a lexan. It's probably a lot of trial and error.
