CUTTING
SMALL
BEADS
Beads
can
be
scraped
or
cut.
The
easy
method
of
scrap¬
ing
is
done
with
the
spear
chisel,
and
works
to
best
advantage
on
beads
separated
by
parting
tool
cuts,
as
shown
in
Fig.
56.
Scraping
is
slower
and
less
productive
of
clean
work
than
cutting,
but
it
has
the
advantage
of
perfect
safety
-
you
won’t
spoil
the
work
with
long
gash
runs.
Cutting
beads
quickly
and
accurately
with
the
small
skew
is
one
of
the
most
difficult
lathe
operations.
Various
work¬
ing
methods
can
be
used,
the
usual
system
being
as
shown
in
Figs.
57,
58
and
59.
The
first
cut
is
a
vertical
incision
at
the
point
where
the
two
curved
surfaces
will
eventually
come
together.
This
cut
can
be
made
with
either
heel
or
toe
of
skew,
Fig.
60
showing
the
toe
being
used.
Now,
place
the
skew
at
right
angles
to
the
work
and
well
up
on
the
cylinder,
as
shown
in
Fig.
57.
The
chisel
is
flat
on
its
side
at
the
start,
and
is
evenly
rotated
through
the
successive
stages
of
the
cut,
as
shown
in
Figs.
57,
58
and
59.
At
the
same
time,
the
chisel
is
pulled
slightly
backwards
to
maintain
the
cutting
point.
The
entire
cut
is
made
with
the
heel
of
chisel.
The
opposite
side
of
the
bead
is
cut
in
the
same
manner,
one
cut
serving
to
pro¬
duce
the
full
shape
in
each
instance.
Beads
cut
in
this
manner
are
beautifully
smooth
and
polished,
and
the
technique
is
well
worth
mastering.

VEE
GROOVES
Cutting
the
vee
groove
demands
much
the
same
techni¬
que
as
the
bead,
except
the
skew
is
hinged
straight
into
the
work
without
rotation,
as
shown
in
Fig.
61.
Only
one-
haif
of
the
vee
is
made
at
a
time,
and
one,
two
or
more
cuts
may
be
needed
on
each
side
to
obtain
the
desired
shape.
As
in
all
cutting
with
the
skew,
the
bevel
next
to
the
cut
must
be
used
as
a
fulcrum,
without
at
the
same
time
allowing
the
full
edge
of
the
chisel
to
catch
and
cause
a
run.
Vee
grooves
can
also
be
made
with
the
toe
of
the
skew,
in
the
manner
already
described
for
squaring
an
end.
