Verified Purchase
I bought this for converting an old Powermatic Model 90 lathe from Reeves drive to step-cone drive. That is cheaper than repairing the Reeves drive. It is also much quieter and gives me lower speeds (down to about 270 rpm) than are possible with the original lathe transmission (slowest was about 700 rpm). Putting two sizes of this pulley on the headstock spindle is what gives me two speed ranges. These sheaves are heavy and well-machined.
