BEARINGS

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. These bearings support the weight of 12 tons and the stresses of the sails turning; remarkably they are the originals from 1832.





THE CROSS & BRAKEWHEEL
The sails are fixed to the large cross which protrudes from the cap. The cross is attached to the brakewheel which sits above the centre of the mill. As the wind moves the sails the brakewheel rotates providing power to all the moving parts of the windmill.






BRAKEWHEEL
The 2.75 meter diameter wheel is made of cast iron with wooden teeth. They are made with wood that has a wavy grain such as apple, pear or oak beam; wood with a wavy grain does not split on impact.
