Bruce Campbell just completed a new sculpture and delivered it to the gallery. Star Clock was influenced by his study of 13th century astrolabes, which allowed one to tell time by the stars or the sun. The wood base, a cast off from a timber framer, informed how the mechanics would work. Most challenging was getting the rod that holds the top—ring within a ring—gimbal device to stand vertically. The brass plates on the front were etched with ferric chloride and then exposed to ammonia fumes. Come to the gallery and turn the crank on this beautiful inclinometer sculpture as you navigate the stars. See more of Campbell's kinetic sculptures on his artist page.
