Design and development of a table-mounted manual drilling machine for the rural purpose

Abstract

This paper presents a simple and flexible table mounted manual drilling machine designed and developed for rural applications to drill metallic and non-hardened material manually. The drilling machine is one of the essential devices with its applications where a circular cross-section hole is required. However, the manually operated drilling machine was developed for small drilling operations. It eradicated the major challenge of the inability to access electricity in most hamlets and villages across the country where solid materials such as wood and metalwork were engaged daily. The lack of power has deteriorated the economy and reduced some essential services to minimum benefit in those vulnerable areas. The high cost of equipment, especially the highly technological machines, has prompted the implementation of the simple but technically based manual drilling machine (MDM). The use of the manual approach in producing holes in solid materials is of more significant advantage in the rural communities where their sources of income and purchasing power are deficient.
