MACHINING ROTORS
Since the lathe is bolted to the hub, any wobble or runout in the hub will be passed on to the machine. Before you can
cut the rotor, you must measure the runout in the machine and compensate for it with two of the four runout adjustment
screws. When the dial indicator reads less than 0.003”, proceed with your cut.
Set Up the Indicator and Measure the Run Out
STEP 3: COMPENSATE FOR LATERAL Run-out
(1 Minute)
Attach the Visegrip to the vehicle hub and position the dial indicator tip against a flat surface on or near the cutting
head or on a flat surface on the motor. Whichever surface you choose, it should be parallel to the rotor surface,
smooth and not curved.
Disengage the feed by pulling out the feed knob. Pull the knob until you feel it click. This will stop the cutting
head from feeding when the motor is turned on.
Turn on the lathe, observe the movement in the dial indicator. You may wish to turn the face of the indicator so
that zero is at the low (furthest counter clockwise) point.
Determine the total needle sweep between the high (furthest clockwise) and low (furthest counterclockwise) read-
ing by counting the number of lines on the dial indicator.
WARNING!
YOUR LATHE IS FITTED WITH A KNOB ON THE BACK OF THE MOTOR. DO NOT TOUCH THE KNOB WHEN THE
MOTOR IS TURNING OR REMOVE THE SAFETY COVER.
