 I'll be using stepped pulleys to drop the speed down anyway, but the
speed control needs to be 'live'.  I don't need a whole lot of range
with the speed control, but you have to adjust the speed a bit to
compensate for the load reduction as the stones cut.  They only like to
operate across a very narrow speed range; too slow means it takes all
day to remove any metal, too fast means the stones load up and don't cut
any more.
