Saw an Antique Brown & Sharpe grinder today. Single large wheel was about 24 " diameter. 3" thick. Maybe used to be hand operated by a big person. Rotated in a tub that could be filled with water. Tub was cast with the Browne & Sharpe name on the side. Maybe 500 pounds. total. Definitely old. Perhaps 100 years. Looked to be powered later in life by a 3 HP motor. Had an anvil at each side of the grinding wheel. Definitely not the precision grinder thet we are all used too. Reminded me of the foot power grinders om my childhood. 70+ years ago. But the wheel is big. Real big. No handwheels or crank so perhaps this was all removed when a motor was added.
Sorry but I did not have my camera with me.
Any leads would be appreciated.
