Background
“The Full Belly Project designs and distributes income-generating agricultural devices to improve life in developing countries.” (www.fullbellyproject.org) Jock Brandis developed a Universal Nut Sheller that decreases manual labor and increases total well being of communities. Our assignment was to modify the design in order to make it suitable for the United States market. The proceeds will benefit the Fully Belly Project’s mission.

Possible alternative materials
For our project we were unable to manipulate the aluminum, so instead we used plexy glass in place of the aluminum. The inner rotor could also be made out of aluminum.
Tools
This project needed a variety of different types of tools including: a machine lathe, a press drill, a heating oven, a hammer, a saw, etc.
Skills needed
A good amount of machinery operation experience is need. This is because it is hard to construct this project without knowing how to use some of the mentioned tools above without experience.
Estimated time of construction
If one was to make this project by them selves, the construction can take about a week. This estimate includes drying times needed to set the glue.
Specifications
Our solution, the Simple Simon, is based on the original Full Belly Universal Nut Sheller design which can be seen in figure 1. The Simple Simon is constructed out of aluminium and wood. The outer cone is aluminium and 12 inches tall with upper and lower diameters in ratio with the original full belly design seen in figure 1. The upper diameter of the outer wall is 5.45 inches. The base is 8.21 inches. The gradient of the outer cone is 83.4 degrees. The inner cone is fabricated out of hard wood and has a height of 5.82 inches with an upper diameter of 5.52 inches and a base diameter of 7.60 inches. The gradient of the inner cone is 80 degrees. The axle runs through the center of the inner cone and extends up through the outer wall where it is attached to a hand crank. Both the inner and outer cone anchor into a hardwood base board 12 inches x 12 inches x 1 inch. A cylinder with a diameter of 7.9 inches and a height of 1 inch extends upward from the base board to provide the outer cone with inner support.
