The thing about using an inexpensive voltage reducer is that house voltage is not always consistent.  It's not gonna be great for fine-tuning on the low end, but you could cut the rpms by 1/3 to 1/4 and try it from there.  The main concern is to have lower speeds for safety.

Torque-wise, it kinda depends on your setup and how much continuous grain is being fed through.  The crusher I'm using is built with skateboard bearings and a light feed and so it's not much of a concern.  Personally, I'd go with a cheap drill.  It'd take the fun out of the project but would be easier to design and adjust.

Cheers.

16000 is way to fast to reduce with sheaves.  I have an 8" x 1.5" reduction on a 1725 rpm saw motor that gives me 320 rpm on the mill.

Find another motor.

A 16,000 rpm motor sounds like a good way to burn through 4 tons of grain in a minute...
I agree with realbeerguy, will probably be better to just get a proper motor.

Man, you guys ruined a fun project  ;)

I guess I figured as much when I saw the motor, but I was just hoping.

So, any good uses for it?

Just thinking it through - how about a worm gear, say http://www.lexarindustrial.com/servlet/the-11007/NRV063-Worm-Gear-100-cln-1/Detail, or building it out component by component.  This product line is available from many vendors:  http://www.bostongear.com/products/open/worms.html

Cheers.
