Portable mini lathe
The document presents a project on developing a portable mini lathe. A group of 6 students led by Sujith R. are developing the lathe under the guidance of their professor. The portable mini lathe will address issues with conventional lathes like bulkiness and fixed location. It will allow for turning, grinding, cutting, and polishing of wood and light metals within a workshop. The lathe's key components include a hand drill as the headstock, wooden bed and tailstock, and scissor jack mechanism for compactness. The lathe is designed for portability, low cost, and enabling basic machining by carpenters using workshop tools.
