PLUMB BOB

A plumb bob is a simple and ancient tool used in construction, carpentry, and other trades to establish a vertical reference line, also known as the "plumb line." It consists of a pointed weight, traditionally made of metal, but it can also be made of materials like brass, steel, or even plastic, attached to a string or a line.

To use a plumb bob, the weight is suspended from a fixed point, allowing gravity to pull it downward and create a vertical line. The string or line attached to the weight acts as a guide, and the reference line it creates is perfectly vertical. This helps ensure that structures, walls, or other elements are accurately aligned with the force of gravity.

The plumb bob is a simple yet effective tool, providing precise vertical measurements and ensuring that various construction and carpentry projects are level and aligned accurately. Its use dates back to ancient times, and its utility remains relevant in modern construction practices.
