Follow Rest
The follow rest in Figure 37 is mounted on the
saddle and follows the movement of the tool. The
follow rest requires only two fingers as the cut-
ting tool acts as the third. The follow rest is used
on long, slender parts to prevent flexing of the
workpiece from the pressure of the cutting tool.
It should be used when the workpiece length to
diameter ratio is 3:1 or greater.
The sliding fingers are set similar to those of the
steady rest—free of play but not binding. Always
lubricate during operation. Remove the follow rest
from the saddle when not in use. After prolonged
use, the fingers will need to be milled or filed to
cleanup the contact surface.

Setting Compound
Slide
The compound slide is used to cut tapers on parts
or to set the proper infeed angle when threading.
It may also be used to cut specific lengths longitu-
dinally, when set parallel to the spindle axis.
The compound slide handwheel has a graduated
dial for precise inch feed increments. The base
of the compound slide has a graduated scale for
angular setup.
To set the angular position:
1.
Loosen the two cap screws, one on each side
of the compound slide (see Figure 38).

2.
Rotate the compound slide to the desired
angular position. Use the scale at the base
of the slide and the indicator marks on the
carriage to set the position.
3.
Tighten the two cap screws. Be sure to not
overtighten, as you may strip threads.
Note: It is nessary to install your 60° degree
tool bit and set it and the compound rest so
it is perfectly perpendicular to a workpiece.
Then using a protractor offset the compound
rest to 29.5° degrees and mark the location
on the cross slide. You will then have a quick
refrence point for setting the ofset angle for
cutting threads.
