Mounted on the slide rest is a frame for holding the knife, and a set-screw for adjusting the angle of the knife to the wheel.
Fig. 499 is a side view of the slide rest for holding and traversing the cutting tool.
This bar carries the slide rest shown, a handle or lever for partly rotating the slide rest, spanning the bed of the lathe.
The L lever carries a pawl which operates a ratchet wheel, placed on the handle end of the slide rest cross feed screw.
The simplest of these methods is by means of a slide rest, such as shown in Fig. 485.
A simple, or single, slide rest contains a carriage and one cross slide, as in Fig. 621.
In long and large work, however, where the motion of the slide rest is slow, tools having right and left-hand side rake are used.
Fig. 660 represents a filing fixture to be attached to the bed in the same manner as the slide rest.
Fig. 661 represents a fixture for wheel and pinion cutting; it is attached to the slide rest.
To put on successive cuts the slide rest is operated, the lever always being lowered till it meets the surface of the lathe bed.
