ABSTRACT:
An apparatus for supporting a blasting wedge relative to a log to be split includes an elongated base frame having forwardly extended tines onto which one end of a log is rolled. A charged blasting wedge is removably supported on a carriage structure which is vertically adjustably supported on an upright backing structure for aligning the wedge with the center of the log. The backing structure is braced relative to the base frame. An improved blasting wedge includes an elongated body having a forwardly tapered forward end portion, a generally cylindrical middle portion and a solid rearward end portion. Multiple longitudinally spaced-apart wick holes are provided through the body in communication with a central bore which is adapted to receive the blasting powder.
