MACHINING ROTORS
Step 4: MAKE THE CUT
(4 Minutes) CONTINUED
6. Now that you have adjusted for depth, tighten the forward lock lever (over the tool arms). This lever must
be tight to minimize vibration. For safety, it is advised at this time that you turn the motor off. Place the
chip deflector/silencer around the rotor and over the cutting tips. Grooves in the chip deflector/silencer
will fit snugly over the cutting tip screw heads when installed correctly. This silencer is very important, and
it should be used on every rotor. There are currently three types of chip deflector/silencers. The first, the
50-703 standard version, is used in most smaller vented rotor applications. The second, the 50-754, has
double thick silencer blocks and a lock clip to increase pressure on the rotor. The 50-754 chip deflector/
silencer works well on the thin solid rear rotors. The third, the 50-744, has thicker wire and a stronger
spring for larger vented rotors on larger cars and trucks.
7. Once cut depth is set, tool arms are locked down, silencer is secure, and draw bar tightness is double
checked, you may turn the motor back on. Press the feed engagement knob to engage the automatic feed.
Provided that you previously set the shut-off cam correctly, the lathe will shut off when the cut is com-
plete. The cut will take two to four minutes depending on the size of the rotor.
Turn the dials clockwise to advance the
cutting tip depth. Each line on the dial
indicates 0.0025"
The chip deflector rides over the cutting
arms as shown above. The chip deflec-
tor should be used every time.
Move the cutting head by turning the knob
shown above, clockwise for away from
the rotor, counter-clockwise for towards
the rotor.
