Answer :

Final answer:

Chuck's faceplates of the lathe are attached to the spindle, allowing for the mounting and machining of materials on a lathe such as the Blanchard lathe.

Explanation:

The faceplates of the lathe are attached to the part of the lathe known as the spindle. The spindle is a critical component of lathes, including the Blanchard lathe, as it is the rotating axis of the machine that holds and drives the workpiece or the faceplate attached to it. Faceplates serve as one of the methods by which materials, such as wood or metal, can be mounted and then machined or shaped. The attachment of a faceplate allows for irregularly shaped workpieces that cannot be easily held by other means, like a chuck, to be securely mounted on the spindle of the lathe for various turning operations. Using a lathe requires understanding its different parts and how they work together to shape materials.
