To start, inspect your weight for defects. A weight (including a fishing weight or a metal toy top).String (including nylon or fishing line).All you need are the following materials to get started: Making your own plumb bob can be fairly simple. In some cases, plumb bobs are even used to ensure that pipes drilled into a foundation are perfectly vertical. A plumb bob may also be used in the construction of a door jam or when finding the correct location to hang large decorations such as a chandelier. Plumb bobs see a lot of work in the construction trade, particularly when it comes to setting walls. Then, the plumb bob is suspended from the vertical surface in question to test if its distance from the said wall is uniform at both ends. The plumb bob has its origins in ancient civilizations, though its basic construction and use remains very similar today.įirst, a shaped weight (often pointed or tapered to a tip) is tied to the end of a coarse string. In essence, a plumb bob (also known as a “plumb line”) is a simple tool designed to help a user determine if a vertical surface is straight, or “plumb.” In this sense, a plumb bob is the functional equivalent of a level, except that it is designed for use on vertical (rather than horizontal) surfaces. All in all, you’ll walk away from this guide with the knowledge needed to use a plumb bob to frame a wall or hang wallpaper successfully.Ĭheck today’s price on Amazon What is a Plumb Bob and What Is It Used For? After that, you’ll learn how to make your own simple plumb bob from basic household items. If you haven’t already used a plumb bob, this guide will teach you the basics of how to utilize one on the job site. Though it may just look like a string with a weight on it, this tool can actually prevent minor discrepancies in a wall’s alignment from becoming a major issue down the line. In particular, you need to familiarize yourself with a plumb bob, an essential tool used for leveling vertical surfaces. While you should get up to speed in using your power tools, you should spend an equal amount of time becoming acquainted with your manual tools, particularly those that ensure your project is as straight and as true as desired. If you’re new to the art of DIY home renovations, then you may not yet be familiar with all of the tools of the trade. It is suggested by industry experts that both the system designers and manufacturers consider this method of tank gauging should no longer be used because of the varying levels of reliability and accuracy of measurement, and the methods high maintenance demands.Handyman's World is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to. Therefore, the level of reliability of this method is potentially poor. Similarly to float-operated wire-guided systems, this method’s components are prone to accelerated wear because of continuous movement of the float on the liquid surface, which applies continuous movement on the mechanical components. The most commonly reported problem with surface detector level measurement systems is that the plumb weight can become jammed in the sensor unit. Unlike servo-operated float gauges that provide continuous measurement, surface detectors are periodic measurement systems. The resulting measurement is then used to calculate the level of material present in the tank. The weight is then retracted into the sensor unit whilst the line is measured. In Surface Detector Level Gauges, a ‘plumb line’ weight is lowered from the sensor unit, which is fixed to the top of the tank, until the weight makes contact with the surface of the contained material.
