Wrawby Postmill - Windmill

Wrawby, Lincolnshire

Wrawby Postmill is a landmark that can be seen from miles around.

Constructed in 1760, the mill originally had common sails (cloth-in-hand), which have now disappeared. This was originally built as an open trestle mill, although the site may well have been previously occupied by a mill.  The roundhouse, of the roofless 'Midland' type was erected in the early 19th century and in this form the mill worked until 1940 by wind, and until the late 40's by engine in an adjacent power mill that had been set up in 1914.

The mill has had several owners over the years and was a working mill until the late 1940s when it fell into disuse and by 1961 was at the point of total collapse and the then owners sought permission to demolish it.

It has been entirely rebuilt, using some original machinery and the post, largely by volunteers led by Jon Sass and Edward Travis between 1962 and 1965.  Using two second-hand sails from Halton Holegate mill and shutters from Maud Foster mill, Boston , flour was made once more in September 1965.   It is now the last surviving post mill in the the county and some say the north of England.

It originally had four common sails, then gained two spring sails, ending up with a full set of spring sails, the last original set being converted from patent sails off a mill at Laceby.  Winding is by tailpole and winch, with a lever to raise the steps clear of the ground.  The body, which like the trestle is very heavily timbered in oak, is steadied by six rollers which run on a curb on the roundhouse wall.

The four pitch pine sails at Wrawby span 60 feet, and the shades on the sails are closed to catch the wind when the mill is working. The sails are clamped to a large iron cross at the front of the windshaft, which has two large elm gear wheels mounted on it. Coupled to these wheels are a set of French Burr stones at the front turned by the brake wheel and used for grinding wheat, while the Peak stones at the rear (turned by the tail wheel) are used mainly in the production of animal feed.

All this machinery is enclosed within the 'buck' or main body of the mill, which sits on the main post. The post in turn, is supported by a trestle which comprises massive oak cross-trees and quarter bars resting on brick piers. The brick round-house became part of the structure at Wrawby in the early part of the l9th Century. The large steps at the rear of the mill are raised by the ' talthur' when the mill is turned into the wind, and the 30 ton mill is then turned using the tailpost. Six cast iron rollers fixed to the timbers at the base of the buck run on top of an oak curb on the round-house, and keep the whole mill steady.

When we visited

The windmill had only two sails on, but you can see where the other two fit.

The windmill is in a small paddock, when we visited there was a horse in the adjoining paddock. The space within the paddock is limited but there appears to be a footpath that runs down the edge of the adjoining paddock that allows you to get back further so that you can take the front, see below left. This gives a better perspective than using a wider angle lens. The lane past the houses to get to it had many flowers on. The top picture was taken from further along the same path, giving an even better perspective, but when I visited this was not easy to get through as a fence had been put up to keep the horse in allowing a very narrow path that was over grown.
