--.... CUTTING EDGE
" ANCEO WRONG CUTTING SCRAPING
I
When used for cutting, the gouge is always held with the
convex side down° It should be rolled approximately 30 ° to
45 ° in the direction in which it isbeing advanced along the
rest; and the cutting edge should be a little in advance of the
handle.
USING THE SKEW
Two skews, the I/2- and 1-in. sizes, are allthat are needed
forgeneral use. Other sizes are available, This tool isnearly
always used to make finish cuts. to cut vees and beads, and
to square shoulders. Properly used, it produces the best
finish that can be obtained with a chisel, It should be used
but little for scraping, as this quickly dulls it.

USING TOE HEEL / _"
For-finish cutting, the skew is held with the cutting edge
considerably in advance of the handle, bevel side down.
Keep the base of the bevel against the work. Good practice
iSto place the skewwe|t over the work, pull it back until the
edge begins to cut, then swing the handle into position to
advance the cut. Both the toe and the heel of the skew can
be used for taking light cuts; but do not penetrate the wood
toodeeply without cutting clearances, asthere is danger of
burning the tip of the tool.
USING THE PARTING TOOL
The parting tool has just one primary purpose: to cuz
stra Jghtinto the workpiece a sdeep as desired, orall the way
through to make a cut-off. It istherefore a very narrow tool
-- 1/8-ir_, wide-- and isshaped to cut its own clearance so
that the edge wil! 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 isseldom held
with the bevel against the work. As the amount of stock
removed is small, a support for the bevel is not necessary.
The tool issimply fed intothe work at an angle (for cutting),
or pointed at the workpiece center (for scraping). It can be
held easil_ in one hand.
USING THE SCRAPDNG CHISELS
A 1/2-in. wide spear point chisel, a !f2-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 purchased in various other
sizes for special purposes. All are very useful for diameter
scraping operations and for circumference scraping, when
cutting methods cannot be employed.
SPEAR ROUND FLAT
POINT NOSE NOSE
The spear point is used for fine scraping and delicate
operations, such as the forming of beads, parellel 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.
USING SHAPER OR MOULDING KNIVES
An old chisel ca n be made to serve as a holder for shaper or
moulding knives. Such knives make it possible to scrape
many interesting shapes in the workpiece surface in one o_
two operations, instead of the many operations required
with standard chisels_ It is generally not practical to use
cutting methods with special shapetools; scraping methods
should be used.
f°
The holder should provide a shoulder against which the butt
end of the knife can be firmlyseated; and the knife must be
securely mounted, either by means of a screw threaded into
the holder, or by compressing it between two prongs bolted
together.
