6.2 Tool selection

Successful wood turning does not result from high speeds, but
rather, from the correct use of turning tools.
A perfect and sharp wood turner tool is a precondition for
professional wood-turning.
Major tools:
Gouge (A, Fig 18), used for rapidly cut raw wood into round
stock, for turning bowls and plates, for turning beds, coves
and other detail (Fig 19).

Scraper (B, Fig 18), used for diameter scraping and to
reduce ridges.
Skew Chisel (C, Fig 18), used to make vees, beads, etc. (Fig
20). The bevel of skew is parallel to the cut.
Parting tool (D, Fig 18), 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 21).
