There are 100,000 bricks in the tapered tower, the windward side of which is covered with metal sheeting to keep damp at bay. The railed staging around the tower at Spout floor level has fine ornamental cast iron supports.

Drive from the Sweeps was taken to the Brakewheel mounted around the Windshaft and then to a large vertical shaft via the Wallower. The shaft passes down to a point below the Stone floor where the Great Spur Wheel drove Stone Nuts which rotated the three runner stones.
