Universal Nut Sheller is a simple hand-operated machine capable of shelling 50 kilograms (110 lb) of raw, sun-dried peanuts per hour. It requires less than $10 USD in materials to make, and is made of concrete poured into two simple fibreglass molds, some metal parts, one wrench, and any piece of rock or wood that can serve as a hammer. It accepts a wide range of nut sizes without adjustment.
