Parallels play a crucial role in machine shop environments where they serve as essential tools for measuring or holding work pieces with precision during drill press or milling machine operations. Typically crafted from high-quality steel and machined to extremely tight tolerances, these parallels ensure accurate results and are available on online marketplaces like Amazon. For instance, this specific model (http://amzn.to/28PGxhU) showcases exceptional quality and performance. With the advancements in 3D printing technology, it is now possible to produce these parallels at home with impressive accuracy. In fact, my own 3D printer has consistently demonstrated its ability to achieve high tolerances, making it an ideal solution for creating a cost-effective and disposable set of parallels specifically designed for personal use. The bars produced by my 3D printer measure 3/16" in thickness, 4-1/2" in length, and vary in width from 3/8" to 1" with increments of 1/8". This versatility allows users to select the perfect parallel for their specific needs, ensuring optimal results during their machine shop operations.
