we ground it down. What I'd like to know is how does one
pedict the effective diameter when the pulley is crowned,
as in the SA800?
I measured the pulley across its widest part (i.e. top of the crown).
My (perhaps flawed) logic was that it was the highest part of the
crown that determined the speed. Were it otherwise, the speed would
be related to the width of the belt.
