6. Machine operation

6.1 Correct operating position

Always support the tool on the tool rest and guide with the
palm of your hand keeping your fingers closed.
(see Fig 8)

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 9), used for rapidly cut raw wood into round
stock, for turning bowls and plates, for turning beds, coves
and other detail (Fig 10).

Fig 9
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.
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.
See speed recommendations.
