Notes on Saw Blades
BLADES BREAK FOR FIVE
PRINCIPAL REASONS
1. Too much tension or too little tension on the blade.
2. Overworking the blade by feeding the work piece too fast.
3. Twisting or bending the blade by feeding the work piece
off-centre.
4. Over use, the blade has reached the end of its useful life.
5. Maximum cutting depth 50mm and exceeding the depth for
which it was designed.
Selecting the right Blade
The scroll saw will accept a wide variety of blade widths and
thicknesses. The width of the blade, the thickness of the blade
and the number of teeth per inch (TPI) are determined by the
type of material and size of the radius being cut. Here are
several examples:
TPI
WIDTH
THICKNESS
MATERIAL
10
2.8mm
0.11”
0.5mm
0.020”
Medium curves on 114” to 1-3/4”
wood, wallboard, hardboard.
15
2.8mm
0.11”
0.5mm
0.020”
Same as above, plus wood
1/8” to 1-1/2” thick
18
2.4mm
0.095”
0.25mm
0.010”
Extra thin cuts on soft woods
to 1/4” and parquetry
As a general rule, select the narrowest blades recommended for
intricate curve cutting and widest blades for straight and large
curve operations.
Pegas Scroll Saw Blade
Pegas Pinned Blades
Pegas Skip Tooth Blades
Pegas Reverse Skip Tooth Blades
Pegas scroll saw blades are right up there alongside the best
blades available on the market and are produced in Switzerland
to a very high standard. Anybody using the scroll saw will enjoy
using these high quality blades and good blades make for
easier working!
Pinned blades are generally a lot more coarse than pinless
blades and they have a much wider kerf. These are ideal if you
are trying to cut straight lines, however they are not very good
for doing internal fret work because of the size of the blade.
Skip Tooth blades come with various tpi. These are great from
the respect of cutting different materials according to the tpi.
If you are cutting more hard wood than softwoods then go for
a coarser tooth blade. They are called skipped blades because
they have a tooth then a space then a tooth and so on. With
these blades the teeth always face down towards the table.
Reversed Skip Tooth blades are the same as skipped blade
except they have around three quarters of the blade facing
down towards the table and about a quarter facing up
underneath the table. The idea being that they cut both sides
of the wood giving you a cleaner cut top and bottom on the
work. Reverse teeth prevent splinters from developing on the
underside of the workpiece because the top teeth do not cut
entirely through the work. They have various tpi and are also
available in double skip reverse to help clear more debris from
the cut.
