This paper describes a technical innovation that utilizes a simple and affordable mechanical device to improve the use of manual drilling in consolidated and highly weathered rock formations. Such mechanical device increases the effective drilling time and reduces the labour requirements. The proposed method uses a rotating capstan that provides a lift and relative effective free-fall mechanism. This capstan kit is designed as an open source innovation for local fabrication and maintenance in asset-poor areas.
