To my younger son's delight, he came across and purchased an antique grinding wheel yesterday from a local antique dealer. The wheel is 24 inches in diameter and 3 inches wide, weighing 125 pounds or so. It came in an ancient packing pallet of dubious structural integrity, giving my son and me a few anxious moments in lifting the wheel from the back of his Subaru and setting it atop a used guitar amp in the garage.
My son says that the wheel is from a Michigan quarry that ceased operations in the 1930s. So, my grandfather or even my great grandfather could have made use of this very grinding wheel.
The next step is for my son to construct a frame for the wheel. Then he will need a treadle apparatus to spin the wheel using foot power. As this technology was perfected early in the last century, my son will soon be searching the Web for historical designs.
The adventure begins.
