THE FLOATING CAP                                       Page 1 of 7


The red and white fantail is perhaps the least appreciated part of the windmill.

It is the mechanism that whenever the winds changes direction, day or night, rotates the entire cap to ensure the sails are facing directly into the wind.





This is the white dome at the top of the windmill which is mounted on the timber head frame.  The white cap and head frame has to be able to rotate by 360 degrees every day of the year so the sails are always facing the wind. It can only achieve this if it “floats” on  tapered roller bearings on top of the building, i.e. it is not fixed.




At the top of the brickwork are 24 cast iron tapered roller bearings (like rolling pins) that enable the cap to move freely around the top of the brick tower.
