It consists of a glass clipboard set firmly on a phenolic plastic panel. The entire apparatus is mounted on rubber supports is order to eliminate sliding while in use. The drawdown surface is 6.4mm thick polished glass, equal in planarity to finemirror glass. A steel clip holds the chart firmly while the drawdown is made. The workable area is equal to the size of the glass plate.
