De Achlumer Molen, Achlum
History
De Achlumer Molen was built in 1851 to drain the Achlumer Noorderpolder. It worked by wind until 1954 when the cap and sails were removed and the smock tower fitted with a thatched conical roof. After that, an electric motor drove the Archimedes' screw.
In 1981, the mill was bought by Stichting De Fryske Mole (English: The Frisian Mills Foundation). The previous owner, Haye Thomas, a Dutch TV journalist, sold the mill for ƒ1. In September 2006 it was decided to restore the mill. The work was undertaken in the summer of 2007. On 18 October 2007 the new cap and sails were fitted to the mill. The restoration was carried out by Bouwbedrijf Hiemsta of Arum.
Description
De Achlumer Molen is what the Dutch describe as an achtkante grondzeiler – a smock mill whose sails reach almost to the ground. It is a three-storey smock mill on a single-storey base. The smock and cap are thatched. The mill is winded by a tailpole and winch. The sails are one pair of Common sails and one pair of Patent sails. The Common sails are carried on the inner stock. They have a span of 18.60 metres (61 ft 0 in); the Patent sails are carried on the outer stock. They have a span of 18.70 metres (61 ft 4 in). They are carried on a cast-iron windshaft which was cast by Koning in 1909. It is 4.15 metres (13 ft 7 in) long. The Brake wheel has 51 cogs. It drives the wallower (27 cogs) at the top of the upright shaft. At the lower end of the upright shaft, the crown wheel (42 cogs) drives the Archimedes' screw via a gearwheel with 39 cogs. The steel screw is 1.20 metres (3 ft 11 in) diameter and 4.45 metres (14 ft 7 in) long, its axle is 500 millimetres (1 ft 8 in) diameter. It is inclined at 22½°. Each revolution of the screw lifts 561 litres (123 imp gal) of water.
