Jet BD-920N - Steady Rest Operation; Setting the Steady Rest; Follow Rest

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 functions 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. 27)
Setting the Steady Rest
1. Loosen three hex nuts (1, Fig. 28)
2. Loosen knurled screw (3, Fig. 28) and open the
sliding fingers (2, Fig. 28) until the steady rest can be
moved with its fingers around the workpiece, secure
the steady rest in position.
3. Tighten knurled screws so that fingers are snug but
not tight against the workpiece Tighten three nuts
(1, Fig. 28). Lubricate the sliding points with
machine oil.
4. When, after prolonged operation, the jaws show
wear, the tips of the fingers may be filed or remilled
Follow Rest
The follow rest is mounted on the saddle and follows 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 under pressure from the turning
tool. (Fig 29)
Set the fingers snug to the workpiece but not overly tight
Lubricate the fingers during operation to prevent
premature wear.
