ABSTRACT:
A log splitting method and apparatus includes placing a charge of blasting powder in a log splitting blasting wedge, axially driving the wedge into one end of a log to be split, adjusting the height of a wedge receiving sleeve on the tower of an anchor structure and moving the anchor structure up against the wedge, igniting the charge in the wedge, thereby blasting the log into several sections. The anchor structure may be secured in place by ground stakes. For making firewood, logs can thus be split first, then blocked. The wedge may alternately be set in the side of a tree stump with the anchor structure supported in a cavity excavated on one side thereof to split the stump for facilitating its removal.
