Corn Mill at Felin Gafnan

Two storey overshot watermill with attached 1-storey mill store set at a lower level. Rubble walls with roofs of small slates, partially grouted. Door to mill offset to R side of W gable wall; a boarded door with segmentally-arched rubble voussoir head. Narrow window to centre of gable at 1st floor, a pointed arch opening with gritstone voussoirs, re-used from a composite millstone, and dripcourse. Small rectangular window set under the eaves to L (N) wall. An old millstone forms the threshold to the mill. Waterwheel to E gable end, in poor condition with rotted wheelshaft, buckets and sole boards. The mill operated with the mill race water flowing over the top of the wheel mill (overshot), but was diverted under the wheel when it was not in use. Attached mill store has doorway to R (in angle with main mill building) and single ventilation slit at W gable apex.

Two storeys, with one pair of stones to the 1st floor. The internal machinery is complete and all of one period, probably the 1840s. Local features include the carrying over of the teeth on the periphery of the spur wheel onto the upper face, so that a layshaft can be driven to activate the hoist and ancillary machines. The downstream runner stone is of a composite structure similar to that used in the arched lintel to the W gable wall, whilst the upstream runner stone is a normal French burrstone, which has lost its maker's plate. Cobble floor and timber hayracks to store.
