CUTTING CURVES
Turn the stock carefully so that the blade follows without twisting. For very abrupt curves, consider using a narrower blade, or a blade with more set. Another solution to this problem is to make relief cuts (Fig. 39).
When you withdraw the workpiece or change the cut, be careful not to accidentally pull the blade off of the wheels. The preference is to turn the stock and saw out through the waste material.
