1 6 .6 STEADY REST
The steady rest serves as a support for shafts on the free
tailstock end. For many operations the tailstock cannot be
used as it obstructs the turning tool or drilling tool, and
therefore, must be removed from the machine. The steady
rest, which function as an end support, ensures chatter-free
operation. The steady rest is mounted on the bedways and is
secured from below with a locking plate. The sliding fingers
require continuous lubrication at the contact points to prevent
premature wear. (Fig.20)
1 6 .7 SETTI NG THE STEADY REST
Loosen three hex nuts. (A,Fig.21)
Loosen knurled screw (B,Fig.21) and open the sliding fingers.
(C,Fig.21) until the steady rest can be moved with its finger
around the workpiece. Secure the steady rest in position.
Tighten knurled screws so that fingers are snug but not tight
against the workpiece. Tighten three nuts (A,Fig.21). Lubri-
cate the sliding points with machine oil.
When, after prolonged operation, the jaw show wear, the tips
of the fingers may be filed or remilled.
1 6 .8 FOLLOW REST
The follow rest is mounted on the saddle and follow the
movement of the turning tool. Only two sliding fingers are
required. The place of the third finger is taken by the turning
tool. The follow rest is used for turning operations on long,
slender workpieces. It prevents flexing of the workpiece un-
der pressure from the turning tool. (Fig.22)
Set the fingers snug to the workpiece but not overly tight.
Lubricate the fingers during operation to prevent premature
wear.
