Using The Parting Tool
The parting tool has just one primary pur-
pose: to cut straight into the workpiece as
deep as desired, or all the way through to
make a cut-off. It is therefore a very nar-
row tool - 1/8-in. wide - and is shaped to
cut its own clearance so that the edge will
not be burned. When used for scraping,
however, it should be backed off regularly
to prevent overheating.
Unlike the gouge and skew, the parting
tool is seldom held with the bevel against
the work. As the amount of stock removed
is small, a support for the bevel is not nec-
essary.
The tool is simply fed into the work at an
angle (for cutting), or pointed at the work-
piece center (for scraping). It can be held
easily in one hand.
Using The Scraping Chisels
A 1/2-in. wide spear point chisel, a 1/2-in.
wide round nose chisel, and a 1 -in. wide
flatnose chisel complete the list of tools
ordinarily used by home craftsmen. Each
of these scraping chisels can be pur-
chased in various other sizes for special
purposes. All are very useful for diameter
scraping operations and for circumfer-
ence scraping when cutting methods can-
not be employed. The spear point is used
for fine scraping and delicate operations,
such as the forming of beads, parallel
grooves and shallow vees. Edges and
bowl contours can be rounded with the
round nose chisel. Any flat surface can be
scraped with the flatnose chisel.
