Rubber Bands Made from Old Inner Tubes
Old inner tubes of bicycles, or other vehicles, may be cut into rubber bands of various widths which will be found to give good service. The tubes should be laid flat on a hard piece of board, or a piece of sheet zinc, and the bands cut off one at a time with a sharp knife held against a straightedge. In cutting them on wood, it is best to use a close-grained stock and to cut across the grain of the wood.
