    Personally, I do not think I'd trust the Jett-Set or any of the
    other brands of these thermoplastics to hold well enough to machine
    metal... Most shrink to some degree, and since they are not metal to
    begin with - tend to "move" a bit. You have to "wrap" the material
    over the edges to keep things from coming out. If you are trying to
    be very precise, I'd stick with metal fixtures and jigs. 

    While most waxes are too heat sensitive to mount into these
    plastics, I believe I have a wax I bought from Lacy's (spelling?)
    that will stand the temperature of vulcanizing... Perhaps it might
    work if you are dead set on using thermoplastic for fixturing wax?
