Which component is NOT part of a cornice brake?

The component that does not belong to a cornice brake is the belt sander. A cornice brake is a specialized tool used in metalworking for bending sheet metal. It typically consists of several parts that enable precise bending of materials, including a bending leaf handle, which allows the operator to control the bending action, a clamping bar handle that secures the metal in place during the bending process, and an adjustable stop that helps achieve accurate and repeatable bends.

The belt sander, on the other hand, is a different tool primarily used for sanding and smoothing surfaces of materials, rather than shaping or bending them. It does not perform any functions related to the bending of sheet metal, which is the primary purpose of a cornice brake. Understanding the specific functions and components of tools used in metalworking is essential to selecting the correct tool for a particular task.
