I built a monster compare what pachai and AC-hacker used. I used mud rotary method of drilling. You can find some pics on page 29. I changed many things since that but I went toward bigger stronger.... My drilling rig has hydraulic drive with over 4000 lb-in torque. I used 15 hp gas engine but switched to 5 hp electric. I am waiting for spring. I have no reason to fight weather

Gravel actually is very difficult to drill. You can not use regular bit because it is very hard and you can not use tricone bit because it gets stuck.
