And the formal bobs are also pointed bobs that become more stylistic by combining different shapes altogether.Īs the tool is mainly the bob itself, you can say the longevity of the tool depends on the material. The geometric shape includes the pointed hexagonal, cone and cylindrical shapes. The naturalistic shape includes the shapes of pointed fruits and vegetables. The bobs have mainly three basic types of shapes, naturalistic shape, geometric shape, and formal shape. The shape of the bob needs to be symmetrical as the thread needs to be attached to the bob’s axis of symmetry and must have a pointed tip for accuracy. Most of the time the brass bob is equipped with a steel tip as the magnetic material helps the bob to align with the center of the earth. Though the earliest bobs were usually made from stone, bronze, and sometimes from bones and ivory, in the present brass and steel are mainly used. Because accuracy, speed, and ease of use is the essential part of any tool. Not only a bob must be heavier, but also a smaller one. Although you can use a mild bob if you’re measuring small heights, you must need a heavier one to measure gigantic things. Since the bob needs to be steady after hanging to take the measurements, the heavier weight rests faster than the lighter weights. You may think that the weight of the bob doesn’t matter, but that’s not right. The laser one is blessed with scientific advantage as it uses only laser light and gives you correct results on the vertical axis. Some additional services like string stabilizer, attaching magnets are provided with some tools nowadays. Although traditional type tools are being used from ancient times, their basic structure didn’t change. Up to the present time, we have mainly two types of plumb bobs, one is the traditional type that comes with string and bob, and the other one is the laser type. Whether you have or don’t have any ideas about the specification of the plumb bobs, the following article is going to help you to know what you have to keep in mind before buying this tool.
