RESAWING
Resawing
is cutting
thick
boards
into
thinner
ones.
It is
actually
a ripping
operation.
(See figure
26.) Small
boards
up to
2-inches
maximum
width
can
be
resawed
in one
pass. Larger
boards
up to 4-inches
maximum
width
require
two passes, one along
each
edge
of the board,
When
two
cuts from opposite
edges are required,
they
should
overlap
1/2-inch
from
the approximate
center
of the board.
If the
first
cut is too deep,
the kerf
will close
and
bind
the saw
on the second
cut, with
some danger
of "'kickback".
Also,
when the kerf closes, the two sides of the cut are no longer
parallel
to the saw blade,
and the saw will cut into
them
and

accuracy
and" appearance.
Keep
the same face
of the board
against
the fence
when making
both
cuts.
When
cutting
boards
thicker
than
3-1/2
inches,
a fence
should
be used which
extends
3-inches
above
the table
top.
When
cutting
boards
thicker
than
4-1/2-inches,
cut both
sides and
finish
the cut with
a hand
saw.
BEVEL AND
MITER
CUTS
Bevel cuts can be made
from either
a cross-cutting
or ripping
position
by tilting the blade
to the desired
angle.
Miter
cuts
can
be made
only
from
a cross-cutting
position
when
the
blade
and
radial
arm are
at some
angle
other
than
90 _
to the fence.
A bevel miter cut is a cut which
is both
beveled
and
mitered.
This cut is made
with
the blade
and
radial
arm
set at the desired
miter
angle
to the fence,
then
the
blade
(only)° is tilted,
with
respect
to the table
top, to the
desired
bevel
angle.
This
cut is usually
referred
to as a
compound
miter.
(See figure
27.)
USE OF THE DADO
HEAD
The dadc_ saw (or head)
is a special
set of blades
for cutting
grooves
c_nd dados.
The Craftsman
8-inch
Kromedge
Dado
Set may be purchased
at any Sears Retail Store or Catalog
Order
House.
The complete
head
consists
of two outside
blades
1/8-inch
thick,
six chipper
blades
1/8-inch
thick
and
paper
washers
for
1/16-inch
width
adjustments.
With
these blades,
grooves
may
be made
in widths
of 1/8-inch,
1/4-inch,
and
additional
widths
in
steps
increased
by
1/16-inch
each,
uplto
a maximum
of
13/16-inch.
Outside
blades
may
be used alone,
but
chippers
cannot
be used
alone.
When
the
maximum
13/16-inch
width
of dado
is
I
used on the motor
shaft,
the outside
loose collar
must not
be used. The width
of the dado
can be reduced
while
using
the loose collar
and two or more passes may be made
with
the work to obtain
the desired
width
of cut. Whenever
two
or
more
chippers
are
used,
the
cutting
ends
should
be
staggered
as evenly
as possible
around
the circumference.
Fractioncl
adjustments
in thickness
of
the
head
can
be
made
by using paper
washers
between
the outside
blades
and
chippers.
Dado
head
operations
are
essentially
the same
as those
operations
using
a standard
saw
blade--but
the
dado
head
takes a bigger
bite, therefore,
the work-piece
should
be held
more firmly.
When
a groove
wider
than
the dado
head
is needed,
make two or more passes, with
cuts spaced
to overlap
a trifle. Dado
work
is performed
in the cross-cut
position.
Ploughing
is done
in the
ripping
position.
If the
rip
or plough
position
is used,
the saw
guard
and
anti-
kickback
pawl
assembly
should
be adjusted
as described
in the
paragraph
"RIPPING".
Rabbeting
is done
with
the
motor
shaft
in a vertical
position.
(See figure
28.) When
rabbeting,
the motor
is indexed
90 ° to the vertical
position
so the blades
are
between
the table
top and
motor,
and
the yoke
is indexed
90 ° clockwise
and
locked.
The saw
is moved
back
on the radial
arm
and
locked
to the arm
when
the amount
of the blade
extending
forward
of the
fence
is equal
to the depth
of the
rabbet
desired.
If the
depth
of the rabbet
is large,
do not attempt
to cut it in one
operation.
Lower
the
radial
arm
until
blades
are
in
a
position
to cut the desired
width
of rabbet
in the edge
of
the board.
The bottom
of the saw guard
should
be parallel
to
the
fence
and
the
discharge
elbow
directed
to
the
rear
of the saw.
MOLDING
OR
SHAPING
This
work
is performed
with
Craftsman
Molding
Cutter
Heads,
and a set of cutters depending
on the type
of mold-
ing
cut desired.
The saw is positioned
in the same manner
as that described
for rabbeting.
(See figure
29.)
Since the
position
of the cutters
can
be adjusted
with
respect
to the
fence
and table
top, any
or all
of the cutter
shapes
may
be used.
The Molding
Cutter
Guard
should
be used with
Molding
Cutter
Head.
ROUTING
AND
DOVETAILING
Routing
and dovetailing
are accomplished
with
the motor
indexed
and
locked
90 ° from
horizontal,
except
that this
time the externally
threaded
stub end (opposite
the normal
blade
end) is between
the motor
and table
top. The follow-
ing
chucks
will
mate,
with
this
external
1/2-20
thread.
