In this video we assemble a DIY micro drill rig (tiny DC motor + drill bit + frame) and a submersible water pump, then test drilling a small “well” and pumping water through tubing. I explain the mechanism, torque limits, and 3 upgrades for better performance.
[pdf] The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, is one of the earliest documented machines. It was so-named after the Greek mathematician who first described it around 234 BC, although the device had been developed in earlier in the century. It is a reversible hydraulic machine that can be operated both as a pump or a power generator.
[pdf] Water bore drilling relies heavily on water well rigs as they are the main equipment used for this purpose. These specialized rigs are tailored to reach deep into the earth’s surface, enabling access to underground water sources.
