Power, or rather, the lack of it, is the biggest problem in rural India. The previous post in this fortnightly column featured an illiterate farmer’s attempts to generate electricity out of a simple water wheel and a windmill. Today we have another innovation that is aimed at tackling the power-problem, though for a specific use case.
Vikas Shinde, a farmer from Pingalwada village in Jalgaon, Maharashtra, has designed a drilling machine that works entirely on manpower, without using electricity. This foot-pedal-operated manual drilling machine is made by using old gear and spare iron parts, and is suitable for drilling large pieces of materials made of metal, wood, PVC etc.
The mechanics behind the machine are simple: it is fitted with a drill bit used for drilling holes in various materials. The drill bit is gripped by a chuck at one end and rotated while cycling the device. The plate is attached with a handle for raising or lowering the position of a job. Power is transmitted from the pedal to the drill through different transmission gears. This is different from the traditional handheld mechanical drills used by carpenters in the way that those have to be operated by rotating a small wheel attached to the bit by hand, and are mostly gearless, therefore unable to achieve the same amount of torque required to drill through harder materials.
