The jigsaw is a tool that
serves a multitude of purposes. It is ideal for making curved cuts
as well as quickly roughing out work before it is trimmed by a router,
or by hand. With the proper blade and powerful enough motor, you
can saw through almost any material.
Another benefit to the jigsaw, it produces less dust and less noise
than cutting with a circular saw. When you are installing at a clients
home and a cut needs to be made, sometimes the jigsaw is a better
choice.
As always, purchase a quality tool. It will be more accurate, have
more helpful features, and be more economical in the long run. Also
inform yourself about the warranties of any new tool.
As a woodworker, you will need to purchase a quality jigsaw. Do
not buy a generic jigsaw with no features as it will be practically
worthless to you. I will try to give you some advice so that you
can buy the best jigsaw for you.
Motor
Todays jigsaws can come with many features. But the life of the
jigsaw, as with all power tools, is the motor. The strength of the
motor is measured in Watts (battery powered models are measured
in Volts). Sometimes you will see the number of Amps listed.
Watts can range from 300 to 600. A woodworker will ususally need
a 400 to 500 Watt model. The speed of the motor action will also
vary, and can go from 500 to maximums of about 3000 strokes per
minute (SPM). Amps will range from 3 to 6. The higher the number,
the morepowerful the tool.
Larger motors are designed to cut through thicker materials, not
necessarily to go faster. They will also have more stroke length
and depth of cut. Most tasks a woodworker will come across will
require cutting a 3/4" board, or a double thickness of 1 1/2",
so the extra cutting depth is not a feature that would be needed
in most cases. (A drawback to deep cutting is that the blade can
become deflected as it cuts, resulting in an angled cut.)
Base Plate
The base, or foot, on good jigsaw models are tiltable to the left
and right, usually to 45 degrees for cutting bevels, some to 90
degrees. Alignment stops along the way make it easy to find common
angles and lock them in.
Attachments can be added to some bases: guides to help with alignment,
plastic inserts to close the kerf area around the blade. (Sometimes
the base will have its own adjustments to close the kerf.)
