Research and Development of HTD 5mm 24T Pulleys

During my second summer with AndyMark inc., there was a realization that the FRC market was missing, affordable, robust, and simple pulleys. The current pulleys on the market lacked strong flanges, were often wider than they needed to be, and weren't exactly the cheapest. AndyMark had new pulleys on the back burner for awhile, so I stepped up and lead the development of these new ones. 

These pulleys uses 2024-AL for the body and 1008-1010 Steel for the flanges. This makes the pulley light on weight but yet it still has very strong flanges. Furthermore I developed the method of attaching the flanges to the body. I researched getting them done from a manufacture outside the building and doing them in house. After many testing a method was found to get the cost of labor per each pulley down to only $0.03. This project taught me a lot about manufacturing processes and the cost of making a product.
