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:
Fig 6
Gouge (A, Fig 6), used for rapidly cut
raw wood into round stock, for turning
bowls and plates, for turning beds,
coves and other detail (Fig 7).

Scraper (B, Fig 6), used for diameter
scraping and to reduce ridges.

the cause.
