The steady rest supports long shafts and can
be mounted anywhere along the length of the
bedway.
Familiarize yourself with the steady rest
components shown in Figure 53 to better
understand its operation.
Steady Rest
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 53 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 54.
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 54.
