    I need to produce a plug to make a mould. Can anyone think of a material besides wood and metal.

    Thankyou :)

    Foam is a good option.

    If it's a one off mold then you can use anything that will hold it's shape, support the weight of the laminate during cure, be reasonably inexpensive, reasonably easy to work into a fair surface and tolerate some heat during the cure.

    Foam as mentioned, concrete springs to mind, clay, plastic...actually, some plastics are lousy....
