Using The Parting Tool

The parting tool has just one primary purpose: 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 narrow

tool - 1/8-in. wide - and is shaped to cut its own clearance

so that the edge will not be burned. When used for scrap-

ing, 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 re-

moved is small, a support for the bevel is not necessary.

The tool is simply fed into the work at an angle (for cut-

ting), or pointed at the workpiece 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,anda1-in.wideflatnosechiselcompletethelistof

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. 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 flat-

nose chisel.

Using Shaper Or Moulding Knives

An old chisel can 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 or two operations, instead of the many operations

required with standard chisels. It is generally not practical

to use cutting methods with special shape tools; scraping

methods should be used. The holder should provide a

shoulder against which the butt end of the knife can be

firmly seated; and the knife must be securely mounted, ei-

ther by means of a screw threaded into the holder, or by

compressing it between two prongs bolted together.

Clear, glass-smooth finishes (especially on soft-woods)

can be obtained by using a block plane set to take a fine

shaving. The tool rest should be raised up approximately

to the top of the workpiece - and the plane should be hor-

izontal, but turned slightly in the direction of travel so that

it will take a shearing cut. Two tool rests, one in front and

the other behind the work, can be used to advantage in

positioning the plane so as to exactly limit the depth of cut

(and finished size of the workpiece).
