Air Hammer!
Shock (vibration) action is very efficient for gravel or bedrock drilling. We try to employ this action in our portable drill system. We asked UAF Mechanical Engineering machine shop Ned Manning and Eric Johansen for building proto type (photo). Ned is very talented engineer to build complicated small mechanics.
At first, we try to modify commercially available air hammer putting in front of auger bit. This in-line air hammer works but not greatly. It need more strong shock at the each hammer action. I hope someday we have more money to build progress type hammer!
