Felling leaning dead oak

Power lines dropped so dead oak tree could be felled. Made notch with extra cut to clean out the notch.
Plunge cut to position wedge to keep cut from closing. Back to other side to plunge cut to form the hinge wood.
Then cut through the holding wood to release the tree. It fell where it was intended to fall. Trimmed up some of the limb wood so the power lines could be put back up. Half hour job.
