It is a typical Irish stone tower mill, with a moveable cap turned by means of an automatic fantail, ensuring that the sails always faced into the wind. When the wind blows directly onto the sails the blades or vanes of the fantail are not moved. However, if the wind veers, it catches the blades and the whole cap turns on an iron ring or ‘curb’, bringing the sails back into the wind. As well as the ground floor the mill has three storeys – a ‘drive’ floor, ‘stone’ floor and ‘hopper’ floor, from the first to third level respectively. The rotating cap sits above the hopper floor. Three pairs of millstones sit at the ‘stone’ floor – one set for making wheatmeal, one for shelling the grains of corn (a process which separated the useless ‘hulls’ from the valuable ‘seeds’ or grain) and a set for grinding grains into oatmeal. The power of the wind is transmitted back from the sails or ‘sweeps’ by means of the central ‘windshaft’ passing back into the cap. On the inner end of the rotating windshaft is the ‘brake wheel’ which drives a bevel gearwheel or ‘wallower’ perched on top of the main (vertical) driveshaft. This power turns the three sets of grinding stones below.
