Too big for my "shop?" LOL

...........had a leaver hooked to a clutch on the top belt pulleys so you did not need to shut the motor down to change speeds. .

This is because in the old old shops machinery was powered by a live, overhead jackshaft



In our small home town, there actually WAS a small shop that used overhead jackshafts. I was in that shop in it's later years, around ??75?? and was ASTOUNDED that one of those was still in operation. Everything in it was antique, including the owner
