Logging Slide Presentation   72 of 82  Back    Next    Index    Heavy Leaners (The boring technique) Begin by making a shallow notch (1/4 dia. of tree). Next, holding the saw bar horizontal to the plane of the notch and at a slightly higher plane, the tree is bored out cutting back from the notch, leaving a good hinge and sufficient holding wood. The same boring procedure is then performed on the other side of the tree, ensuring that the two boring cuts meet properly. Then a back cut is made horizontal to the boring cut, a minimum of two inches below the boring cut; the holding wood at the back severs and the tree falls, guided by the hinge.
