In this report, the improvements of a previously produced cable tool drilling rig are described. The purpose of the rig is to drill water wells for use in Africa in order to provide safe drinking water to many in need. An affordable, effective, and controllable rig is the design goal for this project. With the San Luis Obispo Rotary Club sponsoring the project the design team of WHole Engineering have made necessary design choices to manufacture the product. Actions performed include background research of existing drilling technologies, analysis of top concepts for the controlling mechanism, and selection for the final design. The drilling rig will be modified in many ways to increase control, safety, and provide adequate drilling capabilities. The final design will be operated by a hydraulic system, using chains and sprockets to transmit power to the necessary mechanisms, rather than the tension belts that were present when the design team was assigned to the project.
