making a spherical mirror

Does anyone have a technique to make a large spherical mirror? The focal point needs to be in the neighborhood of a foot. If my experiments are successfull, I'll make it bigger (both longer focal length and larger mirror).

All I really need to figure out is a method of making a section of a sphere. The materials don't really matter so long as I can coat it with something reflective.
