A shaft has a driving end and a driven end. A plurality of driving adaptors with various handles are releasably connected to the shaft driving end. A plurality of driven adaptors with various tools for performing operations within a limited space work area, such as an inaccessible space, a confined space, or keyhole excavation, are releasably connected to the shaft driven end. The driving adaptors are positioned outside of the limited space work area. The driven adaptors are positioned within the limited space work area. The handle is manipulated at the shaft driving end to transmit selected rotational and translational movements through the shaft to the tool to perform operations in the limited space work area. |
