Cutting Curves; Stacked Cuts - Shop fox W1878 Owner's Manual

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.
Stacked.Cuts
One of the benefits of a bandsaw is its ability to cut
multiple copies of a particular shape by stacking a
number of workpieces together. However, before making
stacked cuts, ensure that the table is perpendicular (90°)
to the blade—otherwise, any error in this setting will be
compounded in the workpieces.
To complete a stacked cut, do these steps:
1. Align workpieces from top to bottom.
2. Secure all pieces together in a manner that will not
interfere with cutting. Hot glue on the edges works
well, as do brad nails through the waste portion. (Be
careful not to cut into the brads or you may break
the blade!)
3. Lay out shape you intend to cut on face of top piece.
4. Adjust upper blade guides not more than
top workpiece surface.
5. Make relief cuts perpendicular to outline of your
intended shape in areas where changes in blade
direction could strain woodgrain or cause blade to
bind.
6. Cut stack of pieces as though you were cutting a
single piece. Follow your layout line with blade kerf
on the waste side of your line (see Figure.43.for an
example of a stacked cut setup).
