Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains. Millstones come in pairs. The base or bedstone is stationary.

A runner stone is generally slightly concave, while the bedstone is slightly convex. This helps to channel the ground flour to the outer edges of the stones wher

Counter-Gearing inside the basement of the Stratford Mill. The water wheel at an early grist mill would have been a low to mid breast wheel, 12 to 14 feet in diameter by 6 to 8 feet wide. It would take 3,000 to 5,000 gallons per minute to operate the mill. Most of the moving parts were made of wood. The few metal parts would be gudgeons.
The water mill served as a primary power supply until the advent of the steam engine during the Industrial Revolution. From a modern perspective, the operating principles of the water-powered mill are quite simple. To generate energy, water is directed to a wheel and propels it in a circular motion.
