The hole also allows the plumb bob to be hung from a ceiling or other object, which can be helpful for taking measurements in difficult-to-reach places. This string is used to provide a line of reference for making vertical measurements. The hole in the tip of a plumb bob is used to attach a string or cord. Why is there a hole in the tip of a plumb bob? Repeat this process until you have driven stakes around the entire perimeter of your fence.įinally, attach your fence panels to the stakes, using screws or nails. Wherever the plumb bob falls, drive a stake into the ground. Now, holding the string taunt, walk along the perimeter of your fence line, making sure that the plumb bob hangs directly below the string. Next, tie your plumb bob to the other end of the string. Then, tie one end of your string around the stake. Here is how you use a plumb bob for a fence:įirst, drive a stake into the ground where you want your fence to start. If you are not familiar with fence installation, then a plumb bob will help you make sure that your fence is installed correctly. How do you use a plumb bob for a fence?Ī plumb bob is a very useful tool when it comes to fences. This can be used to make sure that a surface is level or to find the exact center of a circle. The weight pulls the string taut and the string points directly down. The most common type of plumb line is a weight on a string that is allowed to hang freely. How do plumb lines work?Ī plumb line is a line that is perpendicular to a surface. The cord should be long enough to reach the ground from the point where the plumb bob is suspended. The best type of string to use with a plumb bob is a strong, yet thin, cord. What kind of string do I use with a plumb bob? Next, thread the string through the hole and tie a knot to keep it in place. First, make a small hole in the top of the plumb bob. There are multiple ways to do this, but the most common is to use a small nail or screw. The key difference between the two is that a plumb bob hangs vertically while a hose stand supports the hose at an angle.
A hosestand is a support used to steady a hose.

The device used may be purpose-made plumb lines, or simply makeshift devices made from a piece of string and a weighted object, such as a metal washer. Students of figure drawing will also make use of a plumb line to find the vertical axis through the center of gravity of their subject and lay it down on paper as a point of reference. Ī plumb bob may be in a container of water (when conditions are above freezing temperatures), molasses, very viscous oils or other liquids to dampen any swinging movement, functioning as a shock absorber.ĭetermining center of gravity of an irregular shape The early skyscrapers used heavy plumb bobs, hung on wire in their elevator shafts. A variation of this tool has the plumb line hung from the top of an inverted T shape. An A-frame level with a plumb line hung from the vertex was also used to find horizontal these were used in Europe until the mid–19th century. However, if they are mounted on a suitable scale the instrument may also be used as an inclinometer to measure angles to the vertical.Īncient Egyptians used a plumb line attached to the top outer part of a tool resembling a letter E when placed against a wall, the plumb line would indicate a vertical line. A plumb bob and line alone can determine only a vertical reference.
