A book entitled "Power Tool Know How Table Saw" is
available at your nearest Sears Retail Store or Catalog
Store. This book contains considerable data applicable
to the wood lathe.
SELECTION OF CHISELS
Recommended chisels have handles approximately 10
inches long to provide plenty of grip and leverage. Sharp
tools are essential for clean, safe work.., buy tools
that will take and hold clear edges. There are six com.
monly used chisel types. The gouge skew and parting
tool are used for cutting under the surface of lhe work-
piece. The flat nose, round nose and spear point are
used for scraping.
CUTTING AND SCRAPING
When doing a cutting operation, the chisel is held at
an angle so the sharp edge actually cuts below the
revolving workpiece surface to peel off shavings. To do
a scraping operation, the chisel is held at a right angle
to the workpiece and removes fine particles instead of
shavings. Many operations require that cutting chisels
be used for scraping, but scraping chisels should never
be used for cutting. When cutting, materiat is removed
faster than when scraping and produces a smoother
finish which requires less sanding.
CUTTING SCRAPING
WHEN YOU CAN CUT AND WHEN YOU
MUST SCRAPE
If yoL_are removing wood from the circumference of a
workpiece (for example, turning down the outer surface
of a cylinder or the inner wall of a hollow round box)
you may use either a cutting or a scraping action. This
is true because the granular structure of the wood will
allow easy removal of wood at the circumference of the
workpiece in much the same way as a peeling is re-
moved from an apple or a potato,
