Cutting Tips
Face the good side of the material down and
secure it in a bench vise or clamp it down.
Draw cutting lines or designs on the side of the
material facing up towards you. Then place
the front edge of the saw foot on the work and
align the blade with the line to be cut. Hold the
jigsaw firmly, turn it on, and press down (to
keep the saw foot flat against the work) as you
slowly push the saw in the direction of the cut.
Gradually increase the cutting rate, cutting
close to the line (unless you want to leave
stock for finish sanding). As you cut you may
need to adjust or relocate the vise or clamps
to keep the work stable. Do not force the saw
or the blade teeth may rub and wear without cutting and the blade may break. Let the saw do
most of the work. When following curves, cut slowly so the blade can cut through cross grain.
This will give you an accurate cut and will prevent the blade from wandering.
Cutting with a Straightedge
Use a roughcut blade whenever possible. Clamp a straightedge on the work parallel to the line
of cut and flush with the side of the saw foot. (Either first mark the line of cut and then position
the straightedge parallel and at the same distance as between the blade and the side edge
of the foot or first mark the side edge of the foot and then clamp the straightedge on the mark
and parallel to the cut line (Fig. 16).
As you cut, keep the saw foot edge flush against the straightedge and flat on the workpiece
(Fig. 16).
Metal Cutting
When cutting metal, clamp the material down securely. Be sure to move the saw along slowly.
Use lower speeds. Do not twist, bend, or force the blade. If the saw jumps or bounces, use a
blade with finer teeth. If the blade seems clogged when cutting soft metal, use a blade with
coarser teeth.
For easier cutting, lubricate the blade with a stick of cutting wax, if available, or cutting oil
•
when cutting steel.
Thin metal should be sandwiched between two pieces of wood or tightly clamped on a single
•
piece of wood (wood on top of the metal). Draw the cut lines or design on the top piece of
wood.
When cutting aluminum extrusion or angle iron, clamp the work in a bench vise and saw
•
close to the vise jaws.
When sawing tubing and the diameter is larger than the blade is deep, cut through the wall
•
of the tubing and then insert the blade into the cut rotating the tube as you saw.
