1280 RPM.

2. Determine the final diameter, in inches, for

the cut you are about to take.

Note: For this step you will need to aver-
age out the diameters or work with the finish
diameter for your calculations.

3. Use the following formula to determine the

needed RPM for your operation:

(Cutting Speed x 4)/Diameter of cut = RPM

4. With the calculated RPM, examine the spin-

dle speed chart in

Figure 49 or on front of the

headstock, to find the closest match.

Note: In most cases you will need to make a
judgement call on which way to go with the
RPM.

5. Make sure the spindle is completely stopped

before proceeding.

6. Move the spindle speed selectors (Figure

50) to the appropriate RPM setting. Refer to

Figure 49 for available RPM and the selector
combinations.

Note: You may need to rotate the spindle by
hand to get the levers to properly engage.
