Note: Italicized terms are defined in the mill machinery article. Stembridge Mill is a
tower mill, a type of windmill which consists of a
brick or stone tower, on top of which sits a roof or cap which can be turned to bring the
sails into the wind. The advantage of the tower mill over the earlier
post mill is that it is not necessary to turn the whole mill ("body", "buck") with all its machinery into the wind; this allows more space for the machinery and storage. In the earliest tower mills the cap was turned into the wind with a long tail-pole which stretched to the ground at the back of the mill. Later, a looping chain was used which turned the cap with gears, as is used at Stembridge. The other pair has a French Burr runner stone on a conglomerate bedstone. Both pairs of millstones were originally driven
overdrift by the windmill, with the mixed pair later being driven
underdrift by the
steam engine, which also drove a wire machine. The remains of the old bakehouse can be seen at the rear of the mill. ==Millers==
