Here is a scale model of a steam crane. Many of the small parts are made from found materials such as copper staples, old gears, recycled wood, beads, and metal tacks. While one hand-operated crank raises or lowers the boom, the other crank unwinds the hook and cable. Dimensions:
4.5 inches wide (11cm)
8.5 inches long (22 cm)
