Portable water well drilling rig.
We needed a water well at our campsite, of the hunting club. Commercial drillers wanted too much, and small drilling rigs cost too much. So, I built my own. I bought a 2 man post hole auger, powered by a 6.0 B&S engine, with a small gear box on it, and a water swivel on line. The rest was easy. I now have a rig that will go a little over 200 feet! I have included a picture of the rig, with my friend standing beside it.
