One question...
Do you have back gear on your mill?
Our BP is one hp with a one hp VFD on single phase (came that way) and when using smaller shall mill we need to use back gear and go slower but it does work.
If you have a mechanical speed control where slow speed is by gears or belts where torque is increased as speed is reduced then use it.
If variable speed is electronic and not back gear seal it up and trade it as new.
