He needs a larger pulley if going from 60 to 50 ( as a

No argument there--but the size increment is pretty small. Consider
that a typical motor pulley is about 19 mm in diameter, so a 20%
increase would be only about 23 mm.
One could also take Tony's approach and simply cobble up a
crystal-controlled 60Hz source for the motor. Shouldn't be too
difficult--I suspect that the motor doesn't draw more than about 30W.
If you had an excess of 12VDC, you could possibly use an inexpensive
inverter to do the job.
