![]() Once the string is securely attached to the weight, you can then attach the other end of the string to whatever surface you’re hanging the plumb bob off of by tying it or using a simple nail. You can do this by knotting the string in a loop and then wrapping it around the “sinker” or weight at the bottom of the plumb bob. How do I connect string to plumb bob?įor connecting a string to a plumb bob, the best way to proceed is to start by attaching one end of the string to the plumb bob. However, they can be pricey and require more expertise to use. Plumb bobs are more accurate than hose levels and can be used for projects such as framing or hanging doors. The string is then used as a reference to measure how plumb the object is. It is composed of a solid weight attached to a string, and is suspended from a point above the object to be tested. This tool is simple to operate, and is often used to check small horizontal or vertical spaces.Ī plumb bob, on the other hand, is a more precise and accurate tool that is used to check vertical alignment on a larger scale. It is composed of a flexible tube filled with water, some form of gauge, and a level vial. While they are both used for the same purpose, they vary in terms of accuracy and cost.Ī hose level is a simple and inexpensive tool used to check vertical alignment on a small scale. Hose level and plumb bob are both tools commonly used to check vertical alignment. What is the difference between hose level and plumb bob? The instrument is also used in surveying, levelling, and various forms of craftwork that require perfectly vertical lines. ![]() This instrument is commonly used in construction and carpentry, such as when overseeing the erection of a building, determining the fall of a line (for grading and drainage), and ensuring that the walls of a structure are vertically true. Plumb-bobs with a ultra-fine point are advantageous as this makes pin-point precision when marking and transferring points much easier.The bob hangs freely, suspended from the line, allowing the user to draw a perfectly vertical line from the point. Having a string line that protrudes from the dead centre of your plumb-bob will help to ensure accuracy and balance. Purchasing a plumb-bob with a screw on cap is advisable as this ensures that the string line is perfectly centred. This is particularly useful as the tool must be steady in order to make take readings and transfer points accurately. These string lines are will not easily stretch, they are water-proof, rot-proof and resistant to mildew.īraided lines also have the added advantage of not spinning (or at least not as much as twisted string lines tend to). The best string line to purchase is a nylon or polyethylene braided type. It can be difficult to tell just by looking or handling the tool, whether or not it is perfectly balanced, but as a general rule of thumb – if your plumb-bob appears to be a symmetrical shape then it will likely be balanced. ![]() A perfectly balanced plumb-bob should produce accurate readings, especially when transferring points from level to level.
