Abstract:

The report covers tests in which the McCulloch MAC 35A drill with ship auger was evaluated for boring holes in live trees for emplacement of internal explosive demolition charges. In 70 test borings in both hardwood and softwood trees, the gasoline-engine-driven machine with an all-purpose drill attachement and a 1 12-inch diameter, 15-inch long ship auger was found capable of boring holes at rates of 1 12 seconds per inch in softwood trees or 2 seconds per inch in hardwood trees. Easily and simply operated by one man, the 25-pound engine and drill attachement is portable and highly effective for rapid drilling of boreholes in live, sappy trees for the emplacement of explosive charges for tree-felling in jungle clearing operations.
