The gearing system is intact, though hasn't been operated in years. We believe only one or two of the stones were used at any one time. the stone nuts not in operation would be disengaged from the Great Spur Wheel.

The Water Wheel powered the shaft which turned the Pit Wheel. The Pit Wheel would then turn the small Wallower gear on the main shaft which powered the Great Spur Wheel. (see photograph in 'photos')

The Stone Nut's had wooden teeth which engaged with the Great Spur Wheel to turn Stones no.2 & 3.
Stones 1 & 4 were belt driven powered by a wooden pulley on the Main Shaft.

The Layshaft was powered by the Main Shaft and operated the sack hoist and any other machinery using belts and pulleys.
