When surveying the tree and surrounding area, identify potential hazards on the ground, in the tree and where the tree will fall. Trees with severe lean can be dangerous to fell because the tree can move in the leaning direction too quickly, splitting at the base and creating what is known as a “Barber chair” break in the tree. The bore-cut method involves plunging the saw directly through the tree and working forward and back to maintain hinge integrity and to create a back strap that helps hold the tree in place until it is time to drop it.
I’ve seen references to Sighting Marks on a chainsaw for use in aligning the saw cut for felling, but I don’t know what marks these are on my saws.
