If the measurements are the same, that means your wall is plumb. Once it stops swinging, use a ruler to measure the distance between the string and the wall at the top and bottom of the string.
If you touch the string to make the weight stop, you’ll get an inaccurate reading. Make sure to wait for it to stop naturally. Make sure the weight can swing freely without touching the floor. Release the stringīring the string all the way down and let go of the weight.
If you’re measuring a wall, leave about 2-3 inches between the start of the ceiling and the nail. Use a nail or a screw to secure the string of the plumb bob to the uppermost point of the wall, door, or surface that you need to measure. Using a plumb bob to find the true vertical line is not complicated. These devices will project vertical and horizontal laser lines on the wall. There is also a modern adaptation of the plumb bob: laser levels. The weights are still pointed and come with a string to dangle the weight. The first weights were usually made from rocks or stones, then replaced by lead, then finally steel and brass. The modern day plumb bob hasn’t changed much from the original version. However, the plumb bob was still very useful for buildings, bridges, and more. The level was more compact, efficient, and usually gave a more accurate reading. It largely eliminated the need to use a plumb bob as a horizontal measurement device. This is likely because the metal, lead, was used for the earliest weights. The word itself is said to have come from plumbum, a Latin word that means “lead”. It was installed inside a frame that allowed it to turn horizontally and vertically: acting as both a level and a plumb bob. The weight was usually made from a rock or some other kind of heavy object. Used for architecture, sailing, and surveying the skies, the device likely played a major role in constructing the pyramids. Most historians agree that the first plumb bob was invented in Egyptian times. While the accuracy of this technique is debated among professionals, it is based on the same ideas that make the plumb bob device useful. Then, the golfer compares the green on either side of the putter to see which way the ball will break. The golfer squats behind the golf ball when it is on the green and extends the putter toward the hole. The term “plumb bob” is sometimes used in golf to refer to a putting technique. It can be used for all kinds of construction projects, from building a bridge to hanging art on the walls. The plumb bob gives architects and builders a vertical reference point during construction. When the weight is allowed to dangle, it pulls the string into a vertical line that is referred to as a plumb line. The string is usually made from either cotton or nylon, and the weight is typically made from brass or steel. It consists of a small weight with a pointed bottom that is attached to the bottom of a piece of string. Also called a plummet, a plumb bob is a very simple device.
