For an explanation of the various pieces of machinery, see Mill machinery.Stock Windmill is a five storey tower mill with four single Patent sails It has a boat shaped cap winded by a six bladed fantail. The tower is 20 feet 6 inches (6.25 m) internal diameter at ground level and 12 feet 6 inches (3.81 m) internal diameter at curb level. The walls are 22 inches (560 mm) thick to first floor level and 18 inches (460 mm) thick above that. The tower is 40 feet (12.19 m) high overall and the mill is 52 feet (15.85 m) to the top of the cap.
As built, the mill had a stage at first floor level, four Common sails and was winded by hand. It originally drove two pairs of overdrift millstones.
The cast iron windshaft was probably not made for the mill originally. It carries a 9 feet 4 inches (2.84 m) diameter composite brake wheel with 81 cogs which has been converted from clasp arm construction. This drives a cast iron wallower with 25 teeth. The cast iron upright shaft is 5 inches (130 mm) diameter and in three parts, with dog clutches at the fourth and fifth floor. The cast iron great spur wheel is 5 feet (1.52 m) diameter with 76 cogs. It drove three pairs of underdrift millstones of 5 feet (1.52 m), 4 feet 7 inches (1.40 m) and 4 feet (1.22 m) diameter.

“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
