I do agree that the Hydra-Drill is a more of a toy drilling machine for this area. However, I seem to enjoy challenges. With the new Tricone bit and some beefing up of the drill platform, I hope to punch thru the toughest layers.
We also face a challange that the property is land locked and where only a portable unit would work. Ok, the thought of spending $$$$$ Thousands of dollars per hole doesn't sit well in our budget either.
I can only imagine what it must have been like to hand dig a well like you did. If the sides ever collapsed when you were down there
