Resawing
"Resawing" means cutting the thickness of a board
into two or more thinner boards (see Figure 77 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 larger gullet
capacities for clearing sawdust, which reduces heat
buildup and strain on the motor.
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.
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.
