and other detail (Fig 10).
Fig 10
Scraper (B, Fig 9)
, used for diameter scraping and to reduce
ridges.
Skew Chisel (C, Fig 9),
used to make vees, beads, etc. (Fig
11). The bevel of skew is parallel to the cut.
Fig 11
Parting tool (D, Fig 9),
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.

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 13).
Fig 13
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 14 and 15).
