Figure 61. Steady rest components.
To install and use the steady rest:
1.DISCONNECT LATHE FROM POWER!
2.Thoroughly clean all mating surfaces, then place the steady rest base on the bedways so the triangular notch fits over the bedway prism.
3.Position the steady rest where required to properly support the workpiece, then tighten the hex nut shown in Figure 61 to secure it in place.
4.Loosen the clamp knob that secures the two halves of the rest and open the top portion, as shown in Figure 62.

5.Loosen the three leaf screws so the finger roller positions can be adjusted.
6.Use the finger adjustment knobs to position the bottom two finger rollers against the workpiece, as shown in the example of Figure 62.
7.Close the steady rest, then use the finger adjustment knobs to adjust all three finger rollers so that they just touch the workpiece without causing deflection.
Note: The finger rollers should properly support the workpiece along the spindle centerline while still allowing it to freely rotate.
8.Tighten the three leaf screws to secure the settings.
