The repairs were carried out by millwright De Roos of Leeuwarden.

Although in working order, the mill just pumps water in a circuit to demonstrate the process.

[4] De Oudkerkermolen is a smock mill whose sails almost reach the ground.

The four Common sails, which have a span of 15.68 metres (51 ft 5 in), are carried on a cast-iron windshaft.

Each turn of the screw lifts 537 litres (118 imp gal) of water.
