Metalcraft is an art that dates back mamy centuries, yet always proves to be very fascinating and practical. Metals most commonly tooled are aluminum, copper, and brass. The tooling of thin sheets of these materials is a craft that may be done by a first grader or a skilled craftsman. Annealed (softened) metals are best for hand tooling. The desirable thickness varies from 40 gauge to 34 gauge; 36 gauge is most commonly used. The metals are rolled into coils, and are sold by the lineal foot. They can be cut to the desirable size by household shears. The coils range from 12 to 24 inches wide.
