10s M.GATE SHOWING WINDY DRILLER AND PLENTY WATER! 26-2-86

high pit wilma :- THIS is a HOLMAN compressed-air driller[ a windy-driller..] The drill was 9feet long,straight,with no spiral,hexagonal steel section,with a cross-shaped star-bit on the end.Because the drill was straight,without a spiral,water was pumped through the hollow interior,to flush out the curvings,to prevent the drill from becoming fast in the hole [which often happened.]The water had to go somewhere , didn't it?..........

high pit wilma :- What a lovely place to spend an evening.........!
