Cutting Curves

When cutting curves, simultaneously feed and turn the
stock carefully so that the blade follows the layout line
without twisting. If a curve is so abrupt that it is neces-
sary to repeatedly back up and cut a new kerf, use either
a narrower blade or a blade with more TPI (teeth per
inch), or make more relief cuts (See Figure 46).
Always make short cuts first, then proceed to the lon-
ger cuts. Relief cuts will also reduce the chance that
the blade will be pinched or twisted. Relief cuts are
cuts made through the waste portion of the workpiece
and are stopped at the layout 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 need-
ed.
The list below displays blade widths and
the corresponding minimum radii for
those blade widths.
