Hello I’m not actually a blacksmith but in doing some family history I’ve learned that many of my ancestors were. I’m trying figure out what a blast furnace fan described as “So among the few things he brought with him from England was a small centrifugal fan. This fan had four copper blades of about 5 by 7 inches, with a 4 by 4 inch pulley at each end of the fan's shaft. The pulleys were to accommodate two leather drive belts.” Would looks like and I’m not having any luck on the google machine so I thought I’d reach out to the experts. Any help will be greatly appreciated.
