De Mearmin, Marmearmin or Geestermermeermolen is a smock mill in Dokkum, Friesland, Netherlands which was built in 1968. The mill is listed as a Rijksmonument, number 467708.[1]
History
The Mearmin was built between 1968 and 1970 by millwright Auke de Roos of Leeuwarden for the former owner Pier Prins in a privately owned little nature reserve called Geestmermeer. [2] It incorporated parts of a drainage mill which stood at Roodkerk,[3] and also parts from various other demolished mills in Friesland.[4]. The windmill received monument status because of these historic parts in 1990, but only after a lengthy dispute. [2] In later years the windmill fell into disrepair and was in derelict condition by 2009 and under thread of disappearing completely. However in March 2014 the mill was moved to the workshop of Hiemstra millwrights to be restored to working order. After restoration it is to be rebuilt at De sûkerei open air museum in Damwoude.[4]
Description
De Mearmin is what the Dutch describe as a "grondzeiler" . It is a two-storey smock mill on a single-storey base. There is no stage, the sail reaching almost to the ground. The smock and cap boarded. The mill is winded by tailpole and winch. The sails are Common sails. They have a span of 15.10 metres (49 ft 6 in).[5] The sails are carried on a cast-iron windshaft, which was cast by Koning of Foxham, Groningen in 1903. The windshaft also carries the brake wheel which has 50 cogs. This drives the wallower (29 cogs) at the top of the upright shaft. At the bottom of the upright shaft, the crown wheel, which has 37 cogs drives a gearwheel with 34 cogs on the axle of the Archimedes' screw. The axle of the screw is 470 millimetres (1 ft 7 in) diameter and the screw is 1.17 metres (3 ft 10 in) diameter and 3.75 metres (12 ft 4 in) long. The screw is inclined at 22½°. Each revolution of the screw lifts 480 litres (110 imp gal) of water.[5]
