        Dear Masuo & List Members:

        I recommend Rotational molding for prototyping large hollow
plastic parts.
        Patterns can be made via LOM or CNC from which cast aluminum
molds can be made at a substantially reduced cost.
        I can estimate a pattern, cast tool, part price so that you can
perform a price comparison. Please e-mail IGES surfaces to
