This building has three sections: a center gristmill, a left wing sawmill, and a right-side woodworking shop. Ed Mabry built the original mill and both additions about 1910. In the gristmill, customers poured shelled corn into a hopper, and large carefully grooved millstones, separated by fractions of an inch, sheared the kernels. The miller checked the texture of the meal as it entered the bin and adjusted the distance between the millstones if necessary. A second set of millstones ground chop, a coarser product used for livestock feed. Customers paid a toll of 12½ cents a bushel or one-eighth of their total meal. Mabry did not have a bolter to separate finer meal, and he did not grind wheat or other grains. In rainy weather, when the water supply increased, he operated his sawmill, where a sliding carriage moved logs of oak, chestnut, and other species past a circular saw powered by belts and shafts connected to the water wheel. In the woodworking shop, Mabry used a jigsaw and other tools for custom work and to cut spokes and wooden rims for wagon wheels.
