5.Loosen the three thumb knobs so the finger positions can be adjusted.

6.Use the finger adjustment knobs to position the bottom two fingers so they barely touch the workpiece, as shown in Figure 60.

7.Close the steady rest, then use the finger adjustment knobs to adjust all the finger tips so they just touch the workpiece without causing deflection.

Note: The finger tips should properly support the workpiece along the spindle centerline while still allowing it to freely rotate.

8.Tighten the thumb knobs to secure the set- tings.

Note: To reduce the effects of friction, lubricate the fingers with anti-seize lubricant during opera- tion.
