the tool the same number of turns, plus the depth of cut and when ready,
push down the auto feed lever and proceed to take another cut.
BEVEL CUTTING
Bevel cutting involves the use of the
compound slide. This is mounted on
the cross-slide and set at right angles
to it for all normal cutting operations.
This is indicated by the zero mark on
the scale, (B, Fig. 8), lining up with the
mark etched on the body of the cross-
slide.
To set the compound slide so that the
cutting tool will cut a bevel, first
retract the slide until the two hex.
socket head screws (A), are revealed
as shown in Fig 8.
Slacken the screws sufficient to allow
the compound slide to be turned to
the desired angle as indicated on the
scale and secure the slide in this
position by re-tightening the hex.
socket head screws.
The taper, or bevel, is cut by setting
the cross slide appropriately then
using the compound slide feed
handle to advance the cutting tool in
the direction of the arrow as shown in
Fig 9.
SCREWCUTTING
This operation requires a degree of skill and accuracy and should not be
attempted unless you are completely familiar with all aspects of the lathe.
Essentially, the saddle will move towards the headstock under power, the
same as cutting using auto feed, except the rate of feed is greater as
determined by the gear configuration. The cutting tool therefore, is moving
ever closer to the rotating chuck. Great care and concentration must be
exercised to ensure that the two do not meet when the machine is operating
as the possible damage caused could be disastrous.
The lathe is supplied with a leadscrew that will produce Imperial Threads in a
range from 12 to 104 threads per inch. It is important to remember that the
type of thread you need to cut, i.e. UNF, BA, BSP, BSW etc, will be totally
