steady rest
the steady rest serves as a support for long round
shafts (l/d ratio of 3:1 or greater). the steady rest
can be placed anywhere along the length of the
workpiece.
To install/use the steady rest:
1. place the steady rest on the lathe bedways
so the triangular notch fits over the angled
portion of the bedway.
2. tighten the bolt to hold the steady rest firmly
in position (see figure 20).

3. loosen the three hex nuts and knurled
screws so the finger position can be adjusted
to fit around the outer diameter of the part.
4. place the workpiece so it can fit inside the fin-
gers. Secure the two ends of the workpiece
with the chuck and dead center or between
two centers as required (see
figure 21).

5. position the steady rest where desired.
tighten the bolt at base of the steady rest to
secure in place.
6. Set fingers snug while allowing free rota-
tional movement of the workpiece. Secure
the fingers by tightening the three hex nuts.
lubricate the finger tips with an anti-seize
grease during operation.
7. after prolonged use, the fingers will show
wear. Either mill or file the tips for a new con-
tact surface.
