A band saw is often overlooked by many wood
workers but it is a very versatile tools that is capable of
performing rough re sawing. cuts as well as fine decorative
cuts. Band saws are often a safer tools to use then a table
saw since the force of the blade is directed down rather then
back at the operator.
Band saws excel at cutting rough sawn lumber that would otherwise
be too dangerous on the table saw. Rough sawn lumber has a
tendency to want to "close" on the blade and this
can cause a dangerous kick back if using the table saw. The
continuous blade of the band saw is far less prone to kick
back and this makes it much safer to use.
Band Saw Blades
A band saw blade is a continuous blade that is driven by a
motor. The blade is tensioned between to guide wheels that
rotate at high speed. A typical band saw has
14" diameter guide wheels. This is what determines the
throat of the band saw. The throat is the distance from the
cutting portion of the blade to the body of the saw. A 14" diameter
tension wheel will yield a throat slightly less than 14".
The thickness of wood that can be cut on a band saw is determined
by how high the blade guide can lift above the saw table. On
a 14" saw the depth of cut is about 6-3/8".
Blades for a band saw
vary by width, number and spacing of teeth and by the
shape of the tooth. These differences make a band
saw versatile enough to handle a wide range of cuts.
The wider the blade the straighter the cut, with the widest
blades being used for re sawing.
The fewer teeth a band saw blade has the faster it will cut,
but the cut will be much rougher then if made by a blade with
more teeth. The fewer teeth are able to clean the saw dust
from the cut much more effectively.
There are some simple rules of thumb that
can be used as a guideline for choosing the right band saw
blade. Blade manufacturers recommend that there be between
6 and 12 teeth on contact with the wood at any given time.
So a 4 tooth blade would be ideal for wood between 1-12" to
3" and still suitable for wood from 3/4" to 6" thick.
With several blades for different cutting needs a band
saw is a safer alterative for many of the cuts that
you will need to perform.
