There are two methods to develop the device: thin-metal working or 3D-printing. This lesson describes the former. You can read-up lessons on the 3D-printing method here: https://d-lab.mit.edu/sites/default/files/CornSheller_BuildIt_Cast.pdf. This lesson will be completely based on pictures taken from https://d-lab.mit.edu/sites/default/files/CornSheller_DoIt.pdf, copyright D-lab and MIT. In class, we will find ways to improve or redesign the device.
1. Measure a length of thin metal (how much do you think you will need?) and mark it as shown.
2. Then bend the tabs
Make the corn sheller jig (to bend certain parts of the sheet metal). See https://d-lab.mit.edu/sites/default/files/CornShellerJig_DoIt.pdf . Why do we use the materials recommended here? What materials can substitute for them?
Now use the jig to create ridges at the marked locations as shown.
Fold the short edges and join them together.
Crimp the ends.
