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.
-TIA

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.

They should work with any universal motor as long as the current rating
isn't exceeded. One problem you might encounter with a grinder is the
relatively slow start up speed compared to a router and the possibly
resulting high current draw. I used one with my old PowrKraft RAS which
had a univeral motor when I was using the high speed aux spindle for
shaper cutters.

Your grinder does not use a motor with brushes so the speed controller will
not work. There are many "High End" woodturners sharpening their chisels on
cheap high speed grinders without problems.

The fastest way to improve the sharpening ability of a cheap grinder
is by replacing the wheels. Check out the Woodcraft, Lee Valley and
such catalogs and pick up a less aggressive grinding wheel. Less
honing to do afterwards as well.

You still need a very light touch and a can of water handy, but
changing the grinding wheel will cost less than the speed control and
probably give you better results.

You can tell a really good idea by the enemies it makes

IIRC Ryobi makes a 1750 rpm grinder. Probably not the cheap one.

Lowes was selling the Delta low-speed water-cooled bench grinder for $19.95
($50.00 regular price)

They won't work with an induction motor, which most grinders have.
