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 55 to secure it
in place.

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 56.

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.

4.

Loosen the clamp knob that secures the two

halves of the steady rest and open the top
portion, as shown in Figure 56.
