At this temperature it will be the right consistency to flow evenly onto the casting bench. The metal is poured into a trough at the end of the casting bench. A slit across the back of the trough will meter out the metal as the trough is slid along the length of the bench. Sliding the trough along the length of the casting bench leaves behind a glistening layer of metal which will form characteristic spots as it cools. The top of the casting bench itself is made of marble and is covered with canvas.
Cooled metal is removed from the casting bench.
The sheets of metal are attached to the rotating drum of a planer and planed to the desired thickness. Pipe metal is soft and quite malleable. Individual pieces are cut according to patterns and rolled around mandrels to establish their shape. Here a tapered mandrel is used to form the toe of a pipe. The metal is beaten until it conforms fully to the shape of the mandrel.
