We began our model of Archimedes' invention with a platform of wood. We then constructed and carve a "stone" wall out of wood to divide land from water. We made the poles of the device from dowels and the joints and pulleys from scrap metal in the shop. We used polyester resin to create the appearance of liquid seawater.
