It would be good practice! I've got a pulley here for mine, but my late came with just a standard 2 1/2" pulley on the motor shaft, as it has a 3/4 HP motor, which has a larger shaft than a 1/2 HP does. It works just fine the way it is for most things, having only the four speeds available by changing the position of the flat belt. I must admit, however, that more speeds would be wonderful. I've been seriously considering a new 3 phase motor and a VFD for both my mill and for my lathe. All it takes is time and money, both of which have been in short supply lately!
