Please explain the fast and scary method and the slow but
tranquil method of turning a Home Depot grinder into a
jeweller's grinder- polisher. I eyed those last month at Home
Depot and thought - Hmmm. I wonder if...... And then this
thread began. Is synchonicity or chaos?
OK, starting from scratch. You have a grinder . . .Does it have
guards around the wheels??? If the answer is YES, you will have
to remove the wheels and the guards . . .unscrew all the screws
holding the guards and unscrew the bolts holding the wheels. If
done correctly, you should have the motor with two arms (the
shaft) on either side of the motor.
Take a hack saw and saw off the threads on the shaft (there
should be threads on the right and the left side of the motor.)
DO NOT SAW OFF THE ENTIRE SHAFT!!!
Now, note the diameter of the shaft, order a LEFT and a RIGHT
spindle from your favorite vendor. THEY WILL SPECIFY LEFT AND
RIGHT. When they arrive, put the left spindle on the left side
of the shaft, then put the right spindle on the right side of the
I found that spindles with a screw to tighten rather than having
threads inside , were easier to apply . . . I didn’t have to know
whether the shaft was spinning toward or away from me.
As far as the electrical attachment . . . I couldn’t find a way
to attach the electrical part, so I merely left the plug alone, I
put the motor in the space provided in the Dust cabinet. I then,
plugged in the motor and turn that on separately after I turn on
the dust collector.
Oh, my motor had lights over the wheel guards, I simply snipped
those off, and wrapped the ends near the base of the motor in
electrical tape . . . my dust collector has built in lights so
the others were useless to me.
