Spindle RPM
This shaper spindle can be run at 7,000 or
10,000 RPM. The speed is changed by the
placement of the V-belt as shown in Figure 29.
To change the spindle RPM, do these steps:
1. UNPLUG THE SHAPER!
2. Loosen the two spindle slide bolts that hold
the motor mount plate to the spindle slide as
shown in Figure 30. DO NOT remove the
bolts completely.
3. Position the V-belt on the pulleys according
to the desired spindle speed.
4. Slide the motor and motor mount plate
assembly until the V-belt is snug and tighten
the bolts. The amount of V-belt deflection
should be
1
⁄4" when pressed with your thumb.
5. Tighten all fasteners securely.
6. Make sure the V-belt is correctly aligned on
both pulleys.
