Stacked Cuts
To complete a stacked cut:
1. Align your pieces from top to bottom to
ensure that each piece has adequate scrap
to provide a clean, unhampered cut.
2. Secure all the pieces together in a manner
that will not interfere with the cutting. Hot
glue on the edges works well, as does brad
nails through the waste portion. (Be careful
not to cut into the brads!)
3. On the face of the top piece, lay out the
shape you intend to cut.
4. Make relief cuts perpendicular to the outline
of your intended shape in areas where
changes in blade direction could strain the
woodgrain or cause the blade kerf to bind.
5. Cut the stack of pieces as though you were
cutting a single piece. Follow your layout line
with the blade kerf on the waste side of your
line as shown in
Figure 44.
Cutting Curves
When cutting curves, simultaneously feed and
turn the stock carefully so that the blade follows
the layout line without being twisted. If a curve is
so abrupt that it is necessary to repeatedly back
up and cut a new kerf, use either a narrower
blade or a blade with more T.P.I. A blade with
more T.P.I. can cut relatively tighter radii, though
the cut is usually rougher than cuts produced by
a blade with a medium amount of T.P.I.
Always make short cuts first, then proceed to the
longer cuts. Relief cuts will also reduce the
chance that the blade will be pinched or twisted.
Relief cuts are cuts made through the waste por-
tion of the workpiece and are stopped at the lay-
out line. As you cut along the layout line, waste
wood is released from the workpiece, alleviating
any pressure on the back of the blade. Relief cuts
also make backing the workpiece out easier, if
needed.

One of the benefits of a bandsaw is its ability to
cut multiple copies of a particular shape by stack-
ing a number of workpieces together.
Before making stacked cuts, it is essential to
ensure that both the table and the blade are prop-
erly adjusted to 90°. Otherwise, any error will be
compounded with each piece cut from the top to
the bottom of the stack.
Cutting into brad nails that are used to
secure the multiple pieces can cause the
blade to brake and may cause an injury to
the operator. Be extremely careful of where
you are cutting when performing this oper-
ation.
