-20- G1012 18" Bandsaw
A bandsaw blade is a delicate piece of steel that
is subjected to tremendous strain.You can obtain
long use from a bandsaw blade if you give it fair
treatment. Be sure you use blades with proper
width and temper for the various types of cutting
operations.
Always use the widest blade possible. Use nar-
row blades only for sawing small, abrupt curves
and fine detail work. Blades may be purchased
welded, set and sharpened ready-for-use. We
supply bandsaw blades in 1/4", 3/8", 1/2", 1" and
11/2" widths for this saw. Refer to our current cat-
alog for prices and ordering information.
Always select and use good-quality saw blades
and choose the right blade for the right job. Poor
quality blades and improper use are often the
cause of premature blade failure.
Many conditions may cause a bandsaw blade to
break. Blade breakage is, in some cases,
unavoidable, since it is the natural result of the
peculiar stresses that bandsaw blades are sub-
jected to.Blade breakage is also due to avoidable
circumstances. Avoidable breakage is most often
the result of poor care or judgement on the part
of the operator when mounting or adjusting the
blade or support guides.
The most common causes of blade breakage
are: (1) faulty alignment and adjustment of the
guides, (2) forcing or twisting a wide blade
around a curve of short radius, (3) feeding too
fast, (4) tooth dullness or absence of sufficient
set, (5) excessive tension, (6) top blade guide
assembly set too high above the work piece, (7)
using a blade with a lumpy or improperly finished
braze or weld and (8) continuously running the
bandsaw when not in use.
The Grizzly 18" bandsaw accepts blades that are
124" long.The tension adjustment will accommo-
date blades up to a maximum length of 125" and
down to a minimum of approximately 123" in
length.
Blade Information
Resawing is the process of cutting a board into
two or more thinner boards.The maximum board
width that can be resawn is limited by the maxi-
mum cutting height of the bandsaw. Maximum
cutting height for this bandsaw is 91/2".
The G1012 bandsaw is capable of resawing, pro-
vided the saw is set up properly. Use common
sense when resawing. Attempting to resaw too
wide or too dense a board may put excessive
strain on the blade and be dangerous.
The important consideration when resawing is
blade selection. Generally, the wider blade, the
better. In most applications, a hook or skip tooth
style will be sufficient. Also, since most resawn
lumber will be planed smooth, you can choose
blades with fewer teeth-per-inch (from 3 to 6).
While blades with fewer teeth-per-inch produce
rougher cuts, these types of blades offer larger
gullet capacities for clearing sawdust, less heat
buildup, and yield more horsepower per tooth.
Resawing
Figure 16. Proper method for resawing lumber.
1. The bandsaw must be adjusted correctly.
See Blade Adjustment Section.
2. The table must be square to the blade. See
Table Adjustment Section.
3. Use the widest blade available. The blade
must also be in good condition.
4. Use a fence to guide work.
