RCAHMW description of machinery in 1975: ' overshot wheel drives (via a cast-iron shaft) a 12' diam pit wheel, which meshes with an 18" cog driving an axial shaft. This carries a pulley with a belt-drive and two 6' bevel-wheels, each of which drives a stone-nut. The belt from the lower shaft drives a second axial layshaft, from which was taken power for flour-dressing machines (only one remains) and the sack-hoist....The sluices to the leat and launder are controlled from this floor'.
