Measuring tools: features selection and use

Any of the users FORUMHOUSEWho is engaged in the erection of a house or repair, sooner or later asks: what measuring tools he needs? Of course, laser level greatly facilitates and speeds up the work, such as interior decorating. However, it is not devoid of such a drawback as insufficient brightness and long range projected beam in the sunlight. How to be in this case? Maybe I should buy an expensive model, the kit which includes a special receiver that allows you to work leveled at large distances? Do not hurry to run to the store, often a lot of work can be successfully performed using the "grandfather" devices!

Malekate (User FORUMHOUSE):

- to build a house, so to think that because the measuring tools worth buying? I want to purchase a laser builder of planes, that's only if it is justified by the waste?

As practice shows, laser measuring tools is not as simple as they seem at first glance. They must be able to work. A user of our forum with the nickname lobz He believes that the construction of the initial stage, you can get high-quality bubble level, tape measure (long and short), staking cord and gidrourovnya.

Once you are comfortable with the basics of working with these measuring instruments and "nabote hand," you can see if you need to re-buy something else. For example, a laser level.

Helen (User FORUMHOUSE):

- My work is connected with project researches on large objects. Therefore, I regularly use laser tape measure, but I think that in normal construction without it is possible to completely do.

Laser tape accelerates the measurement process is already finished premises. To measure the distance in an open area, it is necessary that the laser beam reflected by any obstacle.

Usa(User FORUMHOUSE):

- When building a house of foam blocks, I used only the normal level, tape measure and gidrouroven. The result is quite satisfied me.

Features of the water level

Gidrouroven works on the principle of communicating vessels. Despite the seeming simplicity of the measuring tool, should understand the features of his work.

Melomandk(User FORUMHOUSE):

- I Bought gidrouroven in the store and ran into the same problem as the flow of water from under the covers bulbs, fixed on the ends of the water level. To set the level, you have to wait a long time. In addition, there is uncertainty in the 2-3 mm. How to avoid it?

When buying gidrourovnya should pay attention to the quality of the hose and flasks. If gidrouroven slowly aligned or "lying" is likely to remain in the hose of air bubbles. They definitely need to be removed!

Efh(User FORUMHOUSE):

- The main problem of purchased gidrourovnya - thin connecting hose.

The greater the tube diameter, the faster "ustakanivaetsya" liquid level in gidrourovnya.

Work gidrourovnya significantly affected by the temperature of water filled in it. For example, if the water is cold, it is very slowly moving through the hose, have to wait until the fluid levels are stabilized.

The same situation arises in the refilling in gidrouroven fluid having a temperature different from that already flooded. The density of water at the same time will differ by a few percent, respectively, start level "lying".

Therefore, despite the large variety gidrourovnya in DIY stores, some members of the forum prefers to make his own.

According to its users in our forum Victor Petrovich, The "right" gidrouroven made from a piece of the oxygen hose and two glass tubes. " Water is desirable to tint and poured into the hose until complete release of bubbles. A water level when carrying ends of the tubes to the water is not flowed, it is possible to plug the finger.

Gidrouroven can carry more so: to break or pinch the tube below the bulb at a distance of 20-30 cm. Store filled gidrouroven, suspending him for two flasks on a nail.

Garvm (User FORUMHOUSE):

- I have my own recipe for the "right" gidrourovnya. Buy transparent silicone hose is in store for aquarists. There's also acquire two cranes. Previously, when using opaque rubber hose, I used glass tubes with risks. Tubes put directly on the hose ends. Now the risks of doing right on the hose. Instead of scratches on the tube can be stretched thin elastic band, which moves back and forth. In the operating position both valves are open during storage - closed.

Major selection criteria gidrourovnya: the tube must be sufficiently rigid, transparent, diameter of 8 to 10 mm.

Although gidrouroven usually fill with water, for the winter it does not fit - freezes. What to do?

Viktor Petrovich(User FORUMHOUSE):

- If you work in the winter I fill gidrouroven pepper brandy.

You can also fill gidrouroven automotive antifreeze or "nezamerzayku". These fluids do not freeze in the cold, exhibit good flowability and, due to color, clearly visible in the transparent tube.

Many novice developers complexity arises when filling gidrourovnya - are air bubbles. To avoid this, the hose is unwound, and lifted one of its ends higher, pour water into it. Expel the remaining bubbles by clicking on the tube with water and driving them to the "output". But there is "antiquated" way.

Melomandk(User FORUMHOUSE):

- I omit one end gidrourovnya in a jar with water, the other clamp lips and inhale sharply (as is usually poured gasoline). Water quickly fills up the phone without the formation of bubbles.

It is believed that with gidrourovnya handier to work together, for example:

1. Leans gidrourovnya tube to the control point.

2. Hold the finger hole in the tube.

3. Mate a second end gidrourovnya rises to the desired location.

4. Remove your finger from the tube and slowly move up, combining the level of risk.

5. As soon as the liquid level of risk and align - yell buddy, so he paid a mark on the wall.

But what if there is no partner, and we have to work with gidrourovnya? Make your own layout using the board with the nickname forumchanin Iosich.

such marking algorithm is as follows:

1. We note the arbitrary reference point, which must be transferred to another location.

2. Fasten one end of the level hose (eg, tape) at the point where you want to move the mark of the reference point, but definitely above the reference point of 20-30 cm.

The second end of the tube to keep the hands, pinching finger outlet.

3. Match with a second level of the end of the checkpoint is applied to the hose plane and up-down movements combine with the water level mark.

Then fasten the hose at this place with tape.

4. We match the first end and do a second mark.

If necessary, the process is repeated for the other points.

How to choose a bubble level?

Besides gidrourovnya, one of the most essential tools in marking work becomes simple level. Work with it usually does not cause difficulties.

The main thing - to choose the exact tool! It seems that doing so is easy. Suffice it to take a couple of levels of different manufacturers, put them side by side on the table, and from 5-7 instruments showing about the same, select the one that you like. Is it really?

Ssshaman(User FORUMHOUSE):

- No matter how many the store level, among all choose only one - accurate. If not, then turns and walks away.

The levels are checked individually necessary, t. To. They are used as conditional standard.

the level of accuracy is checked very easily.

vertical check is performed as follows:

1. Putting a level surface and a vertical position timed bubble.

2. Level pivoted 180 degrees about its axis and attached to the same surface. If the readings are the same, the level can be taken.

Such verification is valid for levels with two or four working surfaces.

Ssshaman:

- To check the vertical at the level of the one working surface it is necessary to find two parallel vertical surfaces, such as the two sides of the door. Accordingly, we are putting a level first with one side of the door, then the other. Indications must be symmetrical.

Horizontal level checked as follows:

1. We put a level on a horizontal surface and pinpoint the position of the bubble.

2. Level pivoted by 180 degrees in a plane orthogonal to the axis level, the readings must be symmetrical.

Also, when checking for the most accurate results under the working level plane can enclose two pencils. In this case, the level there are only two points of support. We therefore exclude the impact of random factors: surface irregularities, inaccurate installation level.

Accuracy test will increase if the level checked in a state where the bubble touches one of the scratches.

Checking is performed every time before starting work, and after any accidental tool drop or suspected that the level began to "lie".

Builders know that the quality level of long eminent manufacturer is very expensive. However, the forum users find out how you can save. We proceed as follows: acquire accurate but short level and attach it with masking tape to the long rule.

BKyler(User FORUMHOUSE):

- Because typically it is relatively inexpensive, as a result we get a great measuring tool in the length of 3 meters. The accuracy of the upgraded level is enough for domestic needs.
