Parting tool (D, Fig 7), used to cut directly into the material,
or to make a cut off. Also used for scraping and to set
diameters.
6.3 Speed selection:
Use low speeds for roughing and for large diameter work. If
vibrations occur, stop the machine and correct the cause.
See speed recommendations.

6.4 Turning between centres
With a ruler locate and mark the centre on each end.
Put a dimple in each end of the shock. Extremely hard woods
may require kerfs cut into the spur drive end of stock
(see Fig 11).
Fig 11
Mount the centred workpiece between the spur drive centre
and the tailstock mounted live centre
Turn the tailstock hand wheel until the live centre well
penetrates the workpiece. Reverse the hand wheel by one
quarter turn and lock the tailstock spindle.
Turn the workpiece by hand to see if it rests securely between
centres and can be rotated freely.
For turning between centres the tool rest is set approximately
3mm higher than centre line (Fig 12 and 13).

6.5 Bowl turning
Turn outside of bowl between centres.
Turn a short tenon the size of the hole in the faceplate
(T, Fig 14). This will allow centring the workpiece.
Fig 14
Mount the workpiece (A, Fig 17) directly to the face plate
using 4 wood screws (C) from the back. Be careful to use
screws short enough not to interfere with the cutting process
but long enough to hold the workpiece securely to the face
plate.
If screw mounting is not allowed at all, the work may be glued
to a backing block (D) and the backing block screwed to the
