#Diy plumb bob how to
Many tradesmen carry it, and especially the older generations often learnt how to use it during their apprenticeship years. The plumb bob is considered to be one of the oldest measuring tools for plumbing - it was used as far back as ancient Egypt, to build the pyramids. As a tool for wallpapering, 80 grammes are sufficient the string should be around 5 meters. Plumb bobs come in various sizes and weights.
Plumb bob and string can be bought separately or in a handy set (usually with tear-proof nylon string). At the upper end, there is an eyelet to thread through a thin piece of string which is used to create straight vertical lines. Plum bobs are characterised by a metal cone which is used as the weight. The same process is applied to the ceiling. This process is repeated until the bottom end is reached. If is is positioned in the middle, the alignment is perfect. It is then positioned at the end of the line whilst closely watching the bubble. The spirit level is then vertically aligned with the pencil mark and a line is drawn along the spirit level. A small pencil mark at the upper wall section should do the trick. The width of the wallpaper is measured and marked on the wall with a ruler or the spirit level. Application during wallpapering:Ī dead straight line is essential for the first length of wallpaper, or the one after an internal corner. At a cost of about £15 for "household" spirit levels, this is a relatively inexpensive investment, especially as this measuring tool has a variety of uses. For straight lines, the length of the spirit level should be about 50 cm or a bit more. For normal DIY purposes, especially wallpapering, a spirit level with one vertical and horizontal bubble is sufficient. For instance, in some models, various measuring vials are positioned vertically and horizontally in the casing. The number of encased vials, as well as their position, can also differ (depending on their actual use).
#Diy plumb bob professional
Whilst mini spirit levels are often used for small and hard-to-reach parts and narrow areas, the larger ones (over 100 cm) are mostly designed for professional construction purposes. They can be between 10 cm to 200 cm long. Spirit levels are available in many different sizes and lengths. Special line marks to the left and right of the encased bubble show whether the alignment is perpendicular or not. It is sometimes called "the eye", "the vial", or simply "the bubble" and it moves around in liquid. The main part is the encased bubble level which is aligned with the measuring area. In terms of colour, the casing is usually red, yellow or aluminium-grey. This useful addition means that it can also be used as a ruler. Spirit levels have a rectangular, elongated casing made of aluminium or plastic which often comes with a measuring scale (in centimetres and millimetres). The basic structure is the same for all models. Spirit levels are an indispensable tool in many trades and can be used as a measuring device for the vertical and horizontal alignment of spaces, surfaces or objects. Spirit levels are extremely easy to use, which is why they are most frequently used for plumb lines along walls. Chalk boxes are only suitable for vertical lines. For plumb lines on ceilings, the chalk box is the best device.
Plumb bob and chalk box require a bit of practice and patience in the beginning. Which one of theses three measuring devices is favoured is purely down to individual preferences. The chalk line/chalk box is a more modern variation of the theme. The plumb bob is one of the oldest ways of creating a dead straight line (also known as "plumbing"). The spirit level is the classic amongst those tools it is easy to use and almost every household has one. Three tools with the same purpose: to create a straight line for the first length of wallpaper or the one after an internal corner, respectively.
