![]() ![]() 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. How does plumb bob measure verticality?Ī plumb bob provides the vertical reference identically as a chalk line provides the horizontal counterpart.Why is there a hole in the tip of a plumb bob?. ![]() How to Use A Plumb Bob: A Step by Step Guide.Rack-A-Tiers Magnetic Damping Laser Plumb Bob ![]() You may think only carpenter, mason, architect or civil engineer should have the tool, but even if you are a regular person, it won’t hurt to keep the best plumb bob within your arm’s reach.

Some bobs have pointed tips that can be bent by repeated use or abuse if the point on yours is bent or out of alignment, replace it.I love creating free content full of tips for my readers, you. Excavation and foundation contractors rely upon the plumb line, and constructing a chimney the tool can indicate whether a flue is running true vertical or veering off plumb. Surveyors sometimes use plumb bobs for lining up points or transferring them. The plumb line in one place can be used to sight an object in another - a pipe, for example - for plumb. Once it is hung and still, the top and bottom points can be marked and used as guides. For example, you can locate fixtures or decorations in relation to an object or surface below (or above) using the plumb line. A spirit level will also accomplish those tasks, but some jobs are much more easily done using the tool. The plumb bob is useful in establishing vertical for a wall in construction or a doorjamb when hanging a door. (Note that the line must be hanging free to get an accurate reading.) The weight, or bob, is then allowed to swing freely when it stops, the point of the bob is precisely below the point at which the string is fixed above. To use the tool, the string is fixed at the point to be plumbed. ![]()
