Part 2/7:
To start, the machinist uses a six-inch four-jaw chuck. The first step involves preparing the old chunk of material destined to be transformed into a faceplate. By correctly fitting the old chunk into the chuck, the machinist can ensure that shavings are piled down neatly and can proceed to face off the material. This initial process includes cutting the sides until achieving a perfect fit.
Maintaining a clean workspace during this process is vital. The machinist emphasizes the necessity of working at room temperature to attain an accurate and sticky fit between the components. The outcome of this careful planning and execution is a faceplate that is not only tight but also remarkably precise.
