Resawing; Cutting Curves - Grizzly G0803Z Owner's Manual

Resawing

"Resawing" means cutting the thickness of a
board into two or more thinner boards (see
Figure 40 for an example). The maximum height
of a board that can be resawn is limited by the
maximum cutting height of the bandsaw.
One of the most important considerations for
resawing is blade selection—a wide blade cuts
straighter and is less prone to blade lead (see the
Blade Lead subsection later in this manual for
more information).
For most applications, use a blade with a hook or
a skip tooth style. Choose blades with fewer teeth-
per-inch (from 3 to 6 TPI), because they offer larg-
er gullet capacities for clearing sawdust, which
reduces heat buildup and strain on the motor.
Figure 40. Example of a resawing operation.
When resawing thin pieces, a wandering
blade (blade lead) can tear through the side
of the workpiece, exposing your hands to
the blade teeth. Always use push blocks
when resawing and keep your hands clear
of the blade.

Cutting Curves

When cutting curves, simultaneously feed and
turn the stock carefully so the blade follows the
layout line without twisting. If curves are sharp or
tight, use a narrower blade with more TPI (teeth
per inch) and make relief cuts to avoid having to
back the workpiece away from the blade.
Always make short cuts first, then proceed to
the longer cuts. Relief cuts reduce the chance of
the blade being pinched or twisted. Relief cuts
are cuts made through the waste portion of the
workpiece and are stopped at the layout line, so
when you're cutting along the layout line, waste
wood is released from the workpiece, alleviating
any pressure on the back of the blade. Relief cuts
also make it easier to back the workpiece out once
the saw blade has come to a stop, if needed.
The list below displays blade widths
and the corresponding minimum radii
for those blade widths.
