Topic: Rocky KO'd (6 msgs / 90 lines)
1) From: Kenneth Rhynas
My Rocky ( about a year and a half old and out of warranty ) has gone on the fritz. It limps along about 100 RPM and sometimes runs in reverse. Occasionally it will kick into high speed. Motor seems to have a short. Does anyone repair these things or is it even worth it to pack it up and pay shipping both ways plus repair expenses? It is lightly used and the burrs are in great shape. Another Rocky or upgrade?

Sounds like the capacitor might be dying, if so, that's conceptually 
an easy fix.  Are you in Los Angeles?

had mine apart to install the constant on switch...not much too them.
I would take it apart and look for a grounded wire.
If you want to get rid of it, I will gladly take it off your hands and pay
you for the s/h...

If the motor is a "universal" series-wound ( like vacuum cleaners, Skil
saws, Solis grinders and electric drills,) it has a set of brushes and a
gear box. The high rpm is good for the centrifugal blower in the vacuum.
Geared down a little, it's good for the saw blade- more gears and it's good
to twist drill bits. Wires don't really just "fall off." If they did so from
both brushes, swapped brushes and each reattached to the opposite brush, it
would reverse the rotation.
More feasible is that the brushes have shattered into an altered shape that
shifts the contact by enough to reverse the motor. That's unlikely, but the
wires sure didn't fall off and swap brushes.

Go figure!

Unfortunately, no. I'm actually in flooded out Iowa. Capacitor huh? Having never cracked the rocky open accept for cleaning, I'm guessing it has a circuit board? I have a feeling my old junior high electricity shop course education  isn't up to this task.

That should be a universal motor.  There is no capacitor.  from your 
initial description of the problem I would guess bad brushes.
