CHOOSING THE RIGHT BLADE AND SPEED
the scroll saw accepts a wide variety of blade widths and thicknesses for cutting wood and other fibrous materials. the blade width
and thickness and the number of teeth per inch or centimetre are determined by the type of material and the size of the radius being
cut.
Note:
As a general rule, always select narrow blades for intricate curve cutting and wide blades for straight and large curve cutting.
5.4
BLADE INFORMATION
scroll saw blades wear out and must be replaced frequently for optimum cutting results. scroll saw blades generally become dull after
1/2 hour to 2 hours of cutting, depending on the type of material and speed of operation.
When cutting wood, best results are achieved with pieces less than one inch (25 mm) thick.
When cutting wood thicker than one inch (25 mm), the user must guide the workpiece very slowly into the blade and take extra care
not to bend or twist the blade while cutting.

SPEED SETTING. See Figure 10.
5.5.1
By turning the speed selector, the saws speed may be adjusted from
400 to 1,600 sPM (strokes Per Minute). to increase the strokes per minute, turn the
speed selector clockwise.
5.5.2
to decrease the strokes per minute, turn the speed selector counterclockwise.

SCROLL CUTTING
In general, scroll cutting consists in following the pattern lines by pushing and turning the
workpiece at the same time. once you have started a cut, do not try to turn the workpiece
without pushing it - the workpiece could bind or twist the blade.
WARNING! to prevent serious personal injury, never leave the saw unattended until the
blade has come to a complete stop.
5.7
INTERIOR SCROLL CUTTING See Figure 11.
5.7.1
one feature of a scroll saw is that it can be used to make scroll cuts within a workpiece
without breaking or cutting through the edge or perimeter of the workpiece.
5.7.2
to make interior cuts in the workpiece, remove the scroll saw blade as explained in the
section on Installing Blades.
5.7.3
drill a 1/4 in. (6 mm) hole in the workpiece.
5.7.4
Place the workpiece on the saw table with the drilled hole over the hole in the table.
5.7.5
fit the blade, feeding it through the hole in the workpiece; then adjust the drop foot and
blade tension.
5.7.6
When finished making the interior scroll cut, simply remove the blade from the blade
holders as described in the section on Installing Blades, and remove the workpiece
from the saw table.

STACK CUTTING. See Figure 12.
once you have become well acquainted with your saw through practice and experience,
you may wish to try stack cutting.
stack cutting may be used when several identical shapes need to be cut. several
workpieces may be stacked one on top of the other and secured to each other before
cutting. Pieces of wood may be joined together by placing double sided tape
between each piece or by wrapping tape around the corners or ends of the stacked
wood. the stacked pieces must be attached to each other in such a way that they can be
handled on the table as a single workpiece.
WARNING! to avoid serious personal injury, do not cut several workpieces at a time
unless they are properly attached to each other.
WARNING! do not let familiarity with your saw make you careless. remember that a
careless fraction of a second is sufficient to inflict injury.
