If you equate scrolling with a clunky saw from your
junior high school woodshop days,
you may be in for a very pleasant surprise. Today’s
scroll saws are easy to use, quiet and very safe, making
scrolling an activity the whole family can enjoy.
Indeed scroll sawing can be fun, relaxing and rewarding.
It also can be frustrating if you do not make a wise
choice when purchasing a saw. Before purchasing, give
serious thought to what you’d like to do with your saw.
For well under $200, you can get a saw that can make
simple cutouts. But if you know already that you want to
do intricate fretwork (or work that requires the wood to
be pierced to make the cutout), you need a saw with some
more features for which you’ll pay more. If you buy a
saw that doesn’t suit your purpose, you will probably:
-
Not like scrolling at all and never use your saw.
-
Stumble along but not really enjoy scrolling or
-
End up selling your saw and buying a better saw—the
one you should’ve purchased in the first place.
 Basic
Saw Designs
Often compared to the action of a sewing machine, the
blade of a scroll saw moves up and down, with the teeth
facing forward and down. The mechanisms that power the
blade can be grouped into three major designs:
-
Parallel Arm–The
original design of the parallel arm saw actually
goes back to before 1870. Two arms run parallel to
each other with the blade attached to the ends of
each arm. There are two pivot points used in this
design, and the blade moves in a nearly true up and
down motion. This is the safest of the modern saws
because when the blade breaks, the top arm swings up
and out of the way, stopping immediately.
-
Double Parallel Link Arm–The
latest design in scroll saw development, it relies
on two parallel arms that go back and forth and
converts this motion at the very tips of each arm
into an up and down blade motion.
-
C-Arm Type–This
design simply is an arm shaped like a “C” with the
blade attached to the ends of the “C.” The C-arm has
only one pivot point and creates a cut that is
aggressive and in an arc. When a blade breaks on
this type of saw, the top portion of the blade
continues up and down until you shut off the saw.
There are two other two designs: rigid arm and
oscillating loop drive system. The rigid arm design was
quite popular in the Delta jigsaws of the ’30s and ’40s.
Most recently Powermatic saws featured this design;
according to the company, they have stopped production.
The oscillating loop system is available on only one
saw, the Eclipse. I won’t get into specifics here since
other sections of the Buyer’s Guide cover details about
this one-of-a-kind, handbuilt saw.
Features to Consider
To make the best purchasing decision, spend some time to
thoroughly think through what you want to get out of
your scrolling activity. Will it be a weekend hobby or a
serious, forty-hour-a-week effort? Prices for saws run
from as little as $80 to over $2,000, with $400 being an
average price. You can find a “lemon” or “gem” in all
price ranges, so be aware and shop carefully. If you
will be an occasional user, such as a hobbyist, perhaps
a $180 saw will do. If you plan on going into the craft
business, you should look for a saw in the $400 to
$1,000 price range. For very high quality and high
production you might have to spend $2,400 or more.
Regardless of what your use and/or price range, purchase
the absolute best saw you can afford.
Another piece of advice: try different saws before you
purchase, if at all possible. Scrolling picnics are the
best place to try saws, and, of course, meet other
scrollers. Big woodworking shows draw major saw
manufacturers and also provide excellent opportunities
for hands-on use. A specialty store like Woodcraft will
have them ready for testing. You may have the least luck
going to a local diy center. These types of stores often
don’t have models set up for “test driving.”
When you’re shopping for a saw, here are a couple of
terms and features you should know:
 Blade-changing
feature:
Nothing will take away from the fun, enjoyment and
relaxation of the scroll saw than a saw that requires
special tools to change the blade or change the blade
tension. Have the salesperson show you how the blade is
changed. Then you change the blade yourself. (The
salesperson has probably changed the blade hundreds of
times and can make it look easy.) If the salesperson
takes out a special tool, run, don’t walk, away!
Blade types: There are two major
kinds of scroll saw blades: pin-end and plain or
flat-end. Pin-end blades have a pin at each end of the
blade in order to hold it in place. Plain end blades are
simply plain and require clamps to hold the end in
place. If you really want to do true scrolling, do not
purchase a pin-end saw, nor one that accepts both. The
pin-end blades are much too large and cannot make sharp,
delicate, interior cuts; most are not very high quality
saws.
Thickness of cut:
This is the maximum cutting thickness you can cut with
the saw. Two inches is about what most saws will cut;
most cuts will not be over 3¼4" thick.
Throat length: This is the
distance between the saw blade and the back of the saw.
Sixteen inches is the minimum but there are some saws
available with a 30'' throat. Sixteen inches to 20
inches is about as large as 95 percent of all projects
require, so unless you have some very unusual needs, the
extra throat length is not necessary.
Table tilt:
The ability to cut on an angle might be important to
some people.
Some saws tilt only one way, usually to the left, up to
45 degrees. Some saws tilt both ways. Unless you plan to
do some special work, that needs the tilt, this may not
be particularly important to you.
Speed:
With scroll saws, speed is measured by the strokes per
minute. Some saws have variable speeds, some have two
speeds, and others have a pulley set-up where you have
to adjust the belt to get the desired speed. It is a
good idea to have at least two speeds, but a
variable-speed saw gives you the most options for
cutting materials other than wood. To cut plastics, for
example, you need a slow speed to reduce heat buildup.
You can also cut paper and metals, too.
Weight:
If you plan on moving your scroll saw a lot, weight
could be a factor to consider.
Vibration:
Try to choose a saw with as little vibration as
possible. There is a big difference between saws, so
check this feature out.
Accessories: There are a few
accessories you should consider purchasing with your
scroll saw.
Stand–Do
not skimp on a stand; a lightweight stand will add extra
vibration and noise. Get a good solid stand.
Foot switch–Is a very handy
accessory as it frees up both hands, makes the saw even
safer to use, and will actually speed up your work.
Scroll saw covers–Help
keep dust off your saw while not in use. (A large
plastic trash bag does the same thing and costs a lot
less.)
Editor’s Hot Tips for Beginners
I, too, was a “new blade” once. When I first started, I
took some wrong paths. I’d like to help you avoid them
so you can get to makin’ sawdust instead of getting
frustrated.
Patterns & Photocopies
-
Make photocopies to preserve your original pattern,
but remember most photocopiers distort in one
dimension. Carefully check your photocopy against
the original. Make any adjustments to your pattern
before cutting.
-
Always spray the PATTERN and not the wood to attach
the pattern to the wood. If you spray the wood,
you’ll have a terrible time removing the pattern.
Buying Wood
-
Thin plywoods for scrolling won’t be at your
do-it-yourself center. Your best bet is to contact
one of the advertisers in this or other wood-related
magazines.
Scroll Saw Blades
-
I bought my first scroll saw from a diy store. The
saw came with a few pin-end blades. Wanting some
different sizes, I returned to the store but came up
empty. I tried another diy place and found some
blades but the packaging was not helpful as I tried
to find the #2 and #5 blades. BEST BET: Blade
companies who advertise in Scroll Saw Workshop. It
seems like a shameless plug, but trust me, they are
the most direct source.
-
HOT TIP: Make sure the blade is installed properly!
The teeth of the blade must be pointing downward to
cut. WITH THE SAW OFF, lightly run your finger up
the blade. You should feel a little bit of
resistance if the blade is installed correctly.
Making the Cuts
-
You’ll probably notice when you start to cut that
you can’t seem to saw in a straight line. It’s the
blade. Due to the manufacturing process, there’s a
slight burr on one side of the blade. To compensate,
take a scrap piece of wood and cut into it to see
the direction the blade is cutting. Shift your body
position relative to this line so as you push the
blade into the wood, you’ll again be cutting
straight.
-
As you begin cutting, keep firm but not-white
knuckled pressure on the wood. If you don’t keep
firm pressure on it, the blade will get a hold and
rapidly move it up and down against the table’s
surface. This is called “chatter.” Besides scaring
you the first time it happens, you can damage the
piece you’re cutting.

TOP
TEN POINTS TO CHECK
BEFORE BUYING A SCROLL SAW
Courtesy of Woodcraft Supply Corporation,
www.woodcraft.com.
•
Throat size—If you are going to be doing a lot of work
that requires deep cuts, don’t buy a 15" or 16" throat
saw, but, instead, check first 20" saws.
•
Motor power—Scroll saws are not high amperage or
horsepower tools, but they do need enough power to cut
through moderately thick, or padded (stacked) stock.
Look for at least 1.25 amperes.
•
Variable speed—Being able to vary the speed makes many
cuts easier to control. Generally, ranges can run from
450 to 1600 or so rpms.
•
Table size and construction—The table needs to be large
enough to support the work the throat will accept. This
varies widely, but generally the larger the table the
better. The table should be machined flat.
•
Dust blower and dust collection hood-ups—At the least, a
dust blower is needed.
•
Table tilt—The table needs to tilt 45 degrees to one
side, and doing so to both sides is better.
•
Ease of blade changes—Tool free is best.
•
Control location—Up-front is best. You don't want to
have to wiggle a hand under the table to change speeds
or shut the machine down.
•
Vibration—Less is much better.
•
Noise—Again, less is better. |
