Foot Treadle Grinder built by Jock Dempsey 1970
It helps to have a can dripping water on the wheel when grinding OR for it to pass through a trough of water. Wheels should not be left standing in water as it softens the stone AND it results in an unbalanced wheel. Heavy Ohio sandstone grinding wheel on heavy wooden frame with foot treadle. Built by Jock Dempsey.
