A common problem is when the level fails and stops showing correctly. It is impossible to work with such a tool, but it is also a pity to throw it into the trash. If a similar trouble happened to you, then today's article will help give your level a second life.
By the way, using the method described below, you can check the new levels sold in stores. I am sure that most of them show incorrectly. So, let's learn to return the horizon to the instrument!
How to determine if your level is lying or not?
This method is probably known to experienced craftsmen. It is necessary to place the instrument on a flat surface, and it is not necessary that it be horizontal. We circle the level at the ends of the rail and remember where the bubble was.
Then we rotate the tool 180 degrees and place it on the marks made. Again we look where the bottle ended up.
If in both the first and second cases the bubble is in the same place - your level is working properly, you can safely work with it. Otherwise, the instrument “lost its horizon” and became unusable. How can he be brought back to life?
Determining if the level can be restored?
Typically, the tool will fail if dropped. First, you need to make sure that the geometry of the rail is normal. Place it on a flat surface such as a cabinet door or glass.
If everything is in order with the rail, set the vial to zero. If the rail is bent, the instrument has no chance of recovery.
How to determine the ideal horizon for a building level?
Before you start positioning the bubble, determine the ideal horizon. He will be the starting point. There are the following options:
- 1. Use a laser level. Aim the laser at the wall, place a level to the line and place the bubble in the correct position.
- 2. Using a reference level. Place two levels on a flat surface: working and non-working. Place the bubble in the second level in the desired position, focusing on the first tool.
- 3. Using an aquarium. Place the level bar against the edge of the aquarium water.
- 4. Back to the school geometry course. Place the level against the wall and place the bubble in the center of the capsule. Draw a line with a pencil or pen.
Then rotate the tool 180 degrees. Align one of its edges with the end of the drawn line and draw another one. Make sure that the bubble does not move from the center of the capsule.
Where the lines separate, use a plumb line to connect their ends. As a result, you will get a triangle with two equal sides. Find the middle of the third face and draw a straight line from it to the opposite corner. It turned out to be a true horizon. On it you can set the bubble to zero.
How do I change the position of the bubble?
In this case, it all depends on what construction the level has:
- if there are screws for adjustment, they should be rotated to the required position;
- if the instrument fell and after that the capsule began to move easily, you can carefully set it manually;
- if the capsule cannot be rotated, gently hit it with a spacer.
To securely fix the building level capsule, you can use superglue by pouring it along the contour. After that, you will get a level with ideal readings, which will serve you "faithfully" for many more years.)
