This is a video of a class project done by Raoul D. Dib and Charbel S. Saleh at the Lebanese University Faculty of Engineering - Roumieh. They manufactured their mechanism from the animation shown in here. I am very happy that my efforts inspires young engineering students, and pleased with their contribution to my web site.
I would like to thank Raoul El Dib for providing the technical drawing of the parts he used in his material feed mechanism. If you are looking to build your own mechanism, I recommend you find the dimensions of your feed mechanism with trial and error. You will learn much more with trial and error than imitating Raoul's dimensions. Here is a project file you might download if you need further help LINK.
