down on the rear screw to move
the tip upwards, or front screw to
move it downwards,
remembering to tighten fully
before rechecking.
DO NOT use for adjustments
greater than 1mm, otherwise the
tools’cutting angles, in relation to
the workpiece, will be altered
with resulting consequences.
OPERATION
A. SIMPLE TURNING
Before starting the machine, as described above, it is imperative that the setup for
the type of work to be carried out is
fully checked .
The following notes are guidelines as to how to set up the lathe in order to carry out
a simple turning operation.
ALWAYS plan your work. Have drawings or a plan on hand together with any
measuring instruments you may require, such as micrometers/verniers/calipers etc.
Mount the work, either in the chuck or on a faceplate, (available as an accessory),
and if necessary, use the tailstock centre for additional support (If the work cannot
be adequately secured by the chuck, or if it is a long piece, or of small diameter).
If a tailstock centre is used, the workpiece should be ‘centred’, using a centre drill,
and the centre mark lubricated before locating in the tailstock centre.
Additionally, ‘Steadies’ may be used which are available from your Clarke Dealer.
If the Tailstock is not to be used, move it out of the way by slackening the two
securing screws, sliding it to the end of the bed then nipping up the two screws.
Select a cutting tool that will produce the desired cut....roughing, finishing, parting,
boring etc., and mount it in the Tool Post, with as little overhang as possible, securing
it using two hex socket head screws in the manner shown in FIG. 5.
(Ideally, the overhang should be approx. 10 mm but not more than 15mm for a
straight tool).
It is IMPORTANT to ensure that the tip of the cutting tool is on the centre line of the
work, or very slightly below it. On no account should it be above the centre line.
Where necessary shims should be used beneath the tool in order to achieve the
correct height, or, minor adjustments, (up to 1mm), may be made by tilting the tool
