A short distance from the harbour at Pagnorvaria is the local water mill, just off the river Peg. The river is diverted down the ‘leat’ and a timber ‘sluce’ controls the rivers flow to the ‘undershot’ wheel which is turned by the power of the water. As the wheel turns the pit wheel insidealso turns. The pit wheel has ‘teeth’ on it which works like a gear with the shaft. This then turns the stone ‘nut’ in the stone case. Add some lego grain and with a few turns you end up with lego grain….. (This model was inspired after a visit to the Museum of London, whether there is a similar model, not in lego)
