Bandsaw Blades

SECTION 6: OPERATIONS

The bandsaw is one of the most versatile

machines in the shop. It can cut miters, com-

pound angles, simple and complex curves, cir-

cles, and a wide variety of irregular shapes. It can

also rip and crosscut, as well as cut a variety of

joints. The bandsaw will also resaw stock into

thinner boards.

There are many adjustment points and compen-

sating differences to consider when operating this

type of saw. Therefore, cutting results can be

somewhat unpredictable if some or all of the cru-

cial adjustments are neglected. Here are a few

simple things you can do to increase the pre-

dictability of your bandsaw’s performance:

1. Always use a sharp, high-quality blade.

Although you might save a few dollars ini-

tially, buying a cheap blade will give you

cheap results. As a rule, spending more

now saves you money later.

2. Use the right blade for the job. Resawing

with a

/16" blade or doing scrollwork with a

1" blade are extreme examples of using the

wrong blade for the job.

3. Allow the saw to cut. Don’t force the

workpiece into the blade. When cutting

curves or irregular shapes, remember that

while negotiating a curve, the blade should

still be cutting wood. Simply turning the

workpiece will only bind the blade and

could break it.

4. Maintain your bandsaw in top condition.

See the following section of this manual for

maintenance procedures.

A bandsaw blade is a delicate piece of steel sub-

jected to tremendous strain. Be sure you use

quality blades of the proper width for the various

types of cutting operations. The Grizzly G1148

15" bandsaw accepts 103" blades.

Always use the widest blade possible for the

workpiece you are cutting. Use narrow blades

only for sawing small, abrupt curves and for fine,

delicate work. Bandsaw blades can be purchased

welded, set, and sharpened ready-for-use from

most saw shops. We also supply bandsaw blades

in widths of

/8",

/4",

/8",

/2", and

/4", for this saw.

Please refer to our current catalog for prices and

ordering information.

Always select and use good-quality saw blades

and choose the right blade for the job. Poor qual-

ity blades and improper use are often the cause

of premature blade failure.

Many conditions can lead to breakage. Blade

breakage is, in some cases, unavoidable, since it

is the natural result of the peculiar stresses that

bandsaw blades are subjected to. Blade break-

age is also due to avoidable causes. 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 break-

age are: (1) faulty alignment and adjustment of

the guides; (2) forcing or twisting a wide blade

around a curve or short radius; (3) feeding too

fast; (4) tooth dullness or absence of sufficient

set; (5) excessive tension; (6) upper blade guide

assembly set too high above the workpiece; (7)

using a blade with a lumpy or improperly finished

weld; and (8), continuously running the bandsaw

when not in use.
