basic ban
saw operation
A band saw is basically
a "curve
cutting"
mach-
ine. It is also used for straight-line
cutting
opera-
tions
such
as cross
cutting,
ripping,
mitering,
beveling,
compound
cutting,
and resawing.
It is
not capable
of doing inside cutting.
This band
saw is designed
to
cut wood
and
wood like products only.
For general type scroll cutting,
follow the pattern
lines
by pushing
and turning
the workpiece
at
the same time.
Do not try to turn the workpiece
while
engaged
in the blade
without
pushing
it;
the workpiece
could bind or twist the blade.
A curve
cut is best
performed
by keeping
the
pattern
line in line with the blade while
turning
the workpiece
before
the radius
of the curve
is
cut. The blade should
cut in the middle
of the
pattern
line (saw kerf) since
wood
cutting
band
saw blades are thin.

SAWING
1.
Adjust the upper guide assembly
to just clear
the workpiece.
.
.
Use both hands
while
feeding
the work into
the blade.
Hold the workpiece
firmly
against
the table. Use gentle
pressure.
Do not force
the work, but allow the blade to cut.
The smallest
diameter
circle
that can be cut
out is determined
by the width of the blade.
A 1/4" wide
blade
will
cut a minimum
dia-
meter of approximately
1-1/2".
Relief cuts are made when an intricate
curve (too
small a radius
for a 1/4-inch blade) is to be cut. A
relief
cut is made by cutting
through
scrap sec-
tion
of workpiece
to curve
in pattern
line,
then
carefully
backing
blade
out. Several
relief
cuts
should
be made for intricate
curves,
then follow
pattern
line
as sections
are cut
off
of
curve
"relieving"
blade pressure.
