1. Make a bore, as deep as possible.
2. Saw to a suitable hinge thickness parallel to the directional notch. To avoid sawing into the hinge, saw straight back approximately one guide bar width before swinging the saw.
3. Saw around the trunk. Swing the cut to the other side to the same thickness of the hinge parallel to the directional notch. Do not forget to insert the wedge or breaking bar before completing the felling cut. It is of the utmost importance that the hinge has an even cut.
