since you found some old mill parts, you may find some old flat belt pulleys. the mill would have different sizes of
pulleys on different pcs of machinery, then they would use line shafts with different pulleys and flat leather belts
to drive the machinery. the whole set-up would be connected to a water wheel. no electric (great idea) if you notice
all the old mills that are left are on a river. later on the replaced the pulleys and etc. with a generator and electric
motors. this is just for you young folks. thanks, marion
