Probably will not work "well" at all. The speed control's work on
universal motors vs. induction motors. More than likely the grinder has an
induction motor.

I see where router speed controls sell in the $25-$50 range and supposedly
they will work with most routers that aren't soft start or already have
variable speed. My question is what is chance of this working with a $40
6
inch non-variable speed bench Home Depot Ryobi grinder.... I would like to
use this grinder to sharpen lathe chisels and I need a slower speed
grinder
for this.
