COPY TURNING
1. Take the template object which is
to be copied and mark diagonal
lines on each end in order to show
the centre point before installing it
in the copy stock position. Pierce
the template with the copy
spindle spur (8) and then tighten
both ends equally to hold the
template as shown in Fig 11.
2. Set the new workpiece in the
lathe by marking the centre point
as above and securing in position
between the head and tailstock as shown in Fig 12.
3. Begin turning by roughing off the
workpiece until it is cylindrical and
ready for fine turning.
4. Check that the copy follower is
resting on the template object
and will follow the outline profile
as the assembly is moved along
as shown in Fig 13.
5. Set the tool post such that the
cutting tool is just level with the
axis of the lathe and workpiece
and begin turning progressively from one end, advancing the tool steadily.
Take small cuts to assess the progress and check that the copy follower
runs smoothly.
6. Progress slowly to ensure the copy
follower roller/pin remains in
contact with the template object
at all times. Take care that the
follower does not bounce on
sudden shape changes. Different
tools may be used according to
the desired shape of the
workpiece; e.g, round-nosed,
square-nosed, spear point, etc.
These may need changing during
the operation.
