Homemade building level. We make a laser level with our own hands from improvised materials How to make an electronic level

The laser level is an indispensable thing in the household. Operation of the device does not require special skills, it is enough to install the device on the required terrain and wait for the lines to be built. Marking is carried out in accordance with the position, it can be vertical or horizontal installation. The finished product is sold on the market stalls at prices that are not affordable for every home craftsman, so there are ways to make the device with your own hands.

Design features of laser levels

The appearance of the device is compact, the mounting design allows you to install on any type of surface. Before making a laser level with your own hands, you need to familiarize yourself with its main components:

• magnetic design;
• tripod elements;
• special fastening belts.

In addition to the installation method, laser-type building leveling systems differ in the method of transmission and projection to the beam surface. Materials applied to specify the exact direction project the highlighted element. Devices indicating the state of the plane have optical elements capable of converting the beam into a plane. To date, there are many levels, however, few installations are in demand by masters of their craft, the subcategories of which are:

• The rotational design of the device allows the optical head to rotate around an axis, which projects accurate readings. The universal device is suitable for various construction works, the reliable case provides protection against hostile environment.
• Several laser level sources allow you to create a positional plane. The device finds application at finishing works of constructions.
• The self-leveling device is completed with an internal pendulum. The optical head is configured for parallel operation with five directions, with a cross-shaped sight. It can be used in finishing works of various types.

The design is indispensable for repair or construction at home, often professionals use the devices. For a home master, acquiring a finished device will cost a pretty penny, and marking a large volume with a regular level takes a sufficient amount of time. Therefore, there are ways to make a laser level with your own hands, production differs in the level of complexity of execution.

Basic materials

The simplest design can be made from unused items with your own hands. It is not difficult to make a level with a laser pointer, it is enough to prepare the necessary material and follow the instructions. Do not neglect the instructions and do it your way, before implementing the change, you need to study the design, because. output parameters may become invalid. For a simple installation you will need:

• an ordinary laser pointer, sold in stationery or children's toy stores;
• porous rubber of sufficient thickness, but small in size;
• a small bubble level of a simple type, which is checked for accuracy before use;
• a wooden block, the size of a matchbox, pre-sanded;
• support in the role of a flat stick;
• plywood sheet 10 × 10;
• a metal clamp corresponding to the diameter of the pointer or a thick plastic tie;
• screws.

After preparing the entire list of materials, with your own hands you can begin to assemble the required product.

The simplest level from a laser pointer

The usual installation option may require financial costs only for the purchase of a laser pointer, the rest of the components are available for every home master. With your own hands, you need to make a suitable mount for the pointer so that it can rotate. A homemade laser level will require the following additional tools:

• pointer;
• timber 2.5 cm in size, 50 cm long;
• electric drill;
• cord;
• stick in the form of a support.

The assembly is carried out in sequence, it is not difficult to perform the actions, it is important to have the material at hand.

1. Holes are drilled in the bar on both sides, a cord is installed in one of them, the other is intended for the indicator.
2. After mounting the laser pointer with your own hands, a rope is attached, the main task of which is to suspend the structure. The diameter of the holes should be slightly larger than the cord, for free play.
3. The rope must be tightened tightly, any suitable stick is used as a support.

The main requirement is the reliable fastening of the support, if this condition is not met, the level readings are considered incorrect.

Foam laser level and water containers

Created a more accurate mechanism is possible at home by adding some components to the design. You will need a convenient container with which you can freely place the mechanism, plasters or plasticine, a floating element, dense foam is well suited as it.

The laser level is made by hand, it has some features during the assembly process, which are important to observe in order to obtain an accurate measuring instrument.

1. A small container, which can be an unused pot or bucket, is filled with water.
2. It is necessary to fix a laser indicator on a piece of foam plastic, the nozzle must be a point, fastening is done with a clamp, plasticine or other available method. Shrinkage is carried out strictly vertically, without deviations, in this case it is possible to miss the accuracy of the entire installation.
3. The tank is installed at the desired height, the pointer turns on.
4. By smoothly changing the position of the indicator, points are marked on the walls of the room, all marks are exactly relative to the horizon.

Measurement accuracy in this case is difficult to achieve, however, in finishing work, this level is quite capable of replacing primitive marking systems.

DIY laser cross

In the household, it is important to qualitatively install interior details, furniture, paintings and many other items on the walls. For these purposes, a self-made level is made, the projection of which at the output looks like a cross. Of the materials, a tripod mechanism from a camera or video camera is used, which can be made by hand, an old disk player.

The tripod is fitted with a cross shape made from laser pointers, with a position that allows rotation in the desired direction. To do this, it is possible to apply the drive component from the disk player. The height adjustment is set by the position adjusting tube. Discs in the amount of several pieces are glued together and mounted to the player's drive. The homemade design is fixed at the end of the work, for this you can use super glue or clamps.

This hand-made design will allow you to adjust the installation in any direction without changing the height of the marking. With such a device, it is possible to most accurately set the level on any surfaces, but manufacturing will require small financial costs.

The main advantages of a homemade tool

It is important to understand when using a do-it-yourself device that it is impossible to obtain ultra-precise data from it. Operations performed by the device can be in open space, short distances, unlike purchased analogues. At home, a modified laser level will allow you to use the mechanism instead of a conventional bubble device.

Main differences:

• The markup speed increases significantly, because. the level sets the exact values ​​on the plane. When working with a partner, it is possible to mark the premises in a matter of minutes, which significantly saves valuable time.
• The error exists, but its value is minimal and suitable for almost all types of finishing work. A simple design will allow even a novice master to use the device.
• The beam length depends on the power of the purchased laser, with large volumes it is possible to increase the parameter using a special material purchased in radio components.

The main advantage of the device is the possibility of projection on a horizontal plane. This feature allows the home master to control the quality of the markup both vertically and horizontally. The laser structure is used for finishing work, furniture installation, and other types of construction. It is also possible to use a self-made level on the street, when building fences or small outbuildings.

Every home master understands the importance of the device, but there is no need to go straight to the hardware store. It is necessary to understand exactly if the work is not so complicated, you can make a mechanism with your own hands from improvised means, significantly saving the budget.

After making a homemade device, you need to correctly configure it. When using the variant with a water measuring system, there are no problems, the main adjustment is required by the supporting structure.

The process goes like this:

• The peg is installed in the floor by driving in or mounting stand. The support is screwed in until it coincides with the bubble level in the ideal position.
• The indicator turns on, aims at the required surface. By careful rotation it is possible to mark the walls.
• A self-tapping screw is screwed in the marked area, the second place is marked nearby, after which the rail is installed.

After adjustment, the level moves a little distance to check if the values ​​match, it is possible to continue working. When working with the tool, it is necessary to observe safety measures, wear protective goggles, and avoid direct contact with the beam in the eyes.

When using a homemade structure, it is important to follow the exact markup, if the device fails, you can get incorrect readings. It is necessary to monitor the vertical or horizontal position of the beam, and when using the foam component, wait until the device takes the desired position.

Today I want to tell you about how you can make a building level yourself from improvised materials ...

From the beginning, I suggest you watch our homemade video:

It happens that you need to put some surface perfectly even, but there is no ordinary building level at hand ... In this article, I just want to tell you about how you can make a building level yourself at home without making any special efforts ... For "large" construction work, this level is certainly not suitable, but for small home finishing work, it is quite a necessary thing...

So, let's begin...

For our future building level, we need:
- a transparent glass jar with a volume of 0.5 liters;
- polystyrene (a foam bottom from any packaging is suitable);
- duct tape;
- needle and thread;
- marker...

To begin with, cut out one small circle from their foam as shown in the photo ...

Next, we take a needle with a thread (the length should be slightly lower than the height of the can) and a piece of adhesive tape or thick adhesive tape and pierce the adhesive tape with a needle from the sticky side, pulling the thread through the adhesive tape ...

Next, we thread a foam circle on half of the needle ... Now we measure the center of the bottom of the can and from the inside we “plant” our thread on the adhesive tape (strictly in the center of the can) ...

Now we pour water into the jar until the needle straightens and the foam circle is slightly under water ...

Next, we take a plastic film, pull it on top of the jar and fix everything with an elastic band as shown in the photo ...

Now our level needs to be "calibrated"... To do this, we put the level on a perfectly flat surface, wait until the needle goes into a calm state and does not deviate, and after that, using a felt-tip pen, we put a point on the film from above, which will be located exactly opposite the needle .. .

The laser level or level is a convenient and useful tool, the need for which arises not only during repair work. However, this tool has a rather high cost, which makes it inaccessible to some of the masters. If it is not possible to purchase, then you can make a laser level with your own hands. Moreover, the manufacturing procedure is not particularly difficult, so any home master can handle it.

The principle of operation of the laser level is that a projection is created on the required object or group of objects. The role of the laser beam is played by an LED emitting a luminous flux. Special prisms and lenses make the beam bright and directional. Such equipment is simply irreplaceable when carrying out finishing and construction works both inside and outside the premises.

A homemade laser level is a great alternative to an expensive laser level. Manufacturers supply mainly 2 types of levels: static and rotary. The main difference between them is that the rotary one is equipped with an electric motor, through which the laser rotates, and a focusing lens, while the static one consists of a prism onto which rays are projected.

The diagram above shows how the level is arranged. The principle of operation of the device is not really complicated, but accuracy is very important. The high cost of such tools is due to the high cost of components that are used for the production of levels. If you need a laser level to use it at home, then you can make it yourself.

How to make a laser level with your own hands

The easiest way to make a level is to use a laser pointer. The cost of manufacturing such a device will be insignificant, since you only need to buy a laser pointer, and make all the other details yourself.

When starting to make a level from a pointer, it is necessary, first of all, to ensure a secure fastening of the element, which at the same time could rotate around its axis. To make a homemade device, you will need a list of such materials, tools and parts:

• laser pointer;
• a wooden beam measuring 25x25 cm and about 0.5 m long;
• drill or screwdriver with drill function;
• cord;
• support.

Let's start making a laser level from a pointer:

1. It is necessary to drill two holes in the bar on both sides parallel to each other. One hole is for attaching the pointer, and the second for the cord.
2. After fixing the laser pointer, you need to fix the cord. The cord is designed to hang the resulting device. The hole for the cord must be of sufficient diameter so that the rope passes freely through it.
3. After the cord is pulled through the hole, it should be tied to the bar and tightened tightly.
4. As a supporting surface, you can use any stick (having sharpened one side in the form of a point, you can stick it into the ground), a shovel, a tripod, etc.

An important rule when using a homemade level is the reliable fixation of the support. After the manufacture of such a device, you should check it for quality of operation. It is recommended to perform the check in the evening so that the point can be clearly seen. Initially, you should hang the tool by the cord in the center of the room. After that, the level should be turned in the right direction, and then make a mark on the wall. Such a self-leveling level can be directed in any direction where marks are needed, and then proceed to work.

The second option for manufacturing a laser level involves the use of foam and a container of water. Initially, you need to take a small container, as well as a piece of plasticine or tape. You will also need a laser pointer and a piece of Styrofoam.

The manufacturing process is as follows:

1. The container should be filled with water to the brim.
2. Attach the pointer to a piece of foam.
3. The container with water is located at the height required for marking.
4. Styrofoam together with a pointer should be placed in water.
5. After that, turn on the pointer.
6. When changing the location of the foam relative to the central axis, points are marked. All points will be located directly on the same level.

It is rather difficult to call such a design ideal, but, nevertheless, this level will have a high degree of marking clarity.

Testing a homemade laser level

Now you can resort to testing a homemade device. To do this, you need to fix the product with a pointed stick. Use a bubble level to align horizontally.

After turning on the laser pointer, it should be aimed at the surface. After projecting the first point, you need to make a mark. By rotating the homemade device, marks should be made. All the points obtained are connected using a metal profile and a pencil.

Pros and cons of homemade levels

After the do-it-yourself laser level is ready, you should not expect it to perform any complex tasks. Such a unit is designed for one-time work, so if your type of activity is related to construction, then it is better to purchase a professional tool. The advantages of a homemade device include:

• obtaining a sufficiently large beam length;
• manufacturing speed;
• no need for financial costs;
• increase in the speed of marking work.

The disadvantage is the fact that this is a homemade tool, so you should not expect high accuracy and complex work from it. With a little ingenuity, you can make a level with your own hands without having to purchase expensive factory models.

When during work, it becomes necessary to mark one line at a great distance, the usual bubble level will be ineffective. But professional construction equipment is not cheap, so you should try to find alternatives to it, for example, use a convenient, affordable tool for marking - a laser level. With your own hands, it can be made from any improvised materials for a minimum time period.

Benefits of using a laser level

A home-made light pointer allows you to apply a mirror, symmetrical markup at a great distance, put down spatial points. The range of such models does not exceed 10 meters, but this distance is enough to perform most of the necessary marking work. Professional devices (construction level, cut pointer) have more functionality, but many of the available features are not always in demand. Therefore, at home, you can get by with a home-made design.

The characteristics of such a level are quite enough to meet the basic requirements and apply the necessary markings, because it:

• provides the required beam range, up to 10 m;
• increases the speed of measurements;
• guarantees an acceptable minimum error.

The main advantage of the device is the positioning of the light beam in a horizontal plane, which allows you to effectively mark structures, control levels, including vertical ones on the wall. In addition to carrying out repair work in an apartment, house and interior design, it is used to lay out the backyard territory, control the construction of fences, facade decoration.

Laser pointer and bubble level

One of the available options for making such a tool at home is to upgrade a conventional bubble level. The idea is to attach a light pointer to the body of the level, which will expand the possibilities of using the tool and allow you to put points on remote planes. If you additionally adapt a tripod with a turntable, then the efficiency of its use will increase markedly.

When making you will need:

• bubble level, medium size;
• laser pointer;
• rubber, hard foam rubber, foam plastic with dimensions 40/15/5 (length / width / height in mm);
• for fastening worm-drive clamps, nylon ties in the amount of 2-3 units.

The level should be taken with handles in the middle of the side face, through which it is more convenient to mount the laser pointer with clamps or ties. The requirements for the pointer are simple - the light point at any distance must remain clear, not blurry. To do this, a cap is scrolled from the side of the laser, under which a focusing lens is hidden. Depending on the direction of rotation, the shape of the point will change. The adjustment is carried out in such a way that the deviations from the original shape of the light spot are minimal, regardless of the distance .

1 - laser pointer; 2 - rubber substrate; 3 - clamps, ties.

The device is mounted on top, where there is an insert with a bubble. First, a substrate is laid, a prepared piece of rubber, foam rubber, polystyrene. Then a light pointer, which is tightly fixed with nylon ties, worm clamps.

The direction of the beam is set strictly parallel to the edge of the level. Adjustment is made by placing the tool on any flat surface of great length, it can be a table top mounted against a wall. The height of the light beam from the base should be the same throughout.

If there are no holes suitable for attaching handles, then they are drilled independently in the most suitable place with a 3 mm drill to securely fix the light pointer. Further mounting steps are similar to those listed above.

To carry out marking in different planes, the tool is applied to the base, set strictly horizontally, vertically. Scrolling it around the axis, the marks are transferred to the walls, ceiling, floor. Instead of a surface, it is allowed to use a tripod with a rotary element with a fixed flat board, a metal plate.

Setting up a homemade pointer

Before starting important marking work, any device made independently, for example, a do-it-yourself laser level, must be calibrated and adjusted. You can do it yourself like this:

• A self-tapping screw up to 120 mm long is screwed into the base on which the level is fixed. Deepening it so that its cap coincides with the line of the laser pointer.
• Turning on the pointer, the beam is directed to the wall, after which the projection site is marked with a pencil and the second screw is screwed into it.
• A profile or a flat piece of drywall, any bar is installed on the screw heads.
• Top laser. If necessary, the bar is leveled relative to the horizon, taking into account the readings of the bubble, tilting the edge closer to the wall.
• After alignment, a new screw is screwed in and the profile is removed.
• Having installed a home-made device on a stand, they carry out its final adjustment, focusing on the hat of the last installed hardware.
• If the device is level, proceed to marking.

Hanger application

Any suspended massive object will rotate freely around an axis pointing straight down. If the pointer is fixed perpendicularly, then its beam will draw a horizontal line on all boundary walls.

A wooden block is taken, into the upper end of which two screws are screwed along the edges. Their hats should protrude by about 1 cm. Any thick thread is tied to them, preferably one that is slightly stretched, or thin copper wire. In the middle of the thread, another piece is tied, with which the workpiece will be hung on a tripod or hook.

From the bottom of the bar, using rubber bands, worm clamps attach a laser pointer, achieving its perpendicular position. The direction is checked with a conventional bubble level. By changing the length of the suspension thread, the beam is set relative to the first mark on the wall. Scrolling the bar with a pointer attached to it, further marking the longitudinal line is carried out.

To view its location in the plane, the beam with the suspension thread is slightly twisted in one direction. Released, it will begin to spin in the opposite direction under the influence of gravity, and the pointer will draw a strictly horizontal line along the walls. The error is not more than 1–2 mm.

Using a water container

You can make a simple design with a high degree of marking accuracy from materials available at home. To do this, you will need to prepare a water tank, a piece of polystyrene foam (polystyrene foam), a pointer, any sticky material - plasticine, plaster.

• First, the container, which can be used as a bucket, pan, is filled to the brim with water.
• The laser pointer is installed on the foam, trying to place it more evenly, and fastened with plasticine, plaster, rubber bands.
• The container is set at the required height.
• Styrofoam with a pointer is placed in the tank.
• Move it to the on position.
• By changing the direction of the light pointer, turning it around the axis, the beam is projected onto the marked surfaces and the projection places are marked. All points relative to the horizon will be strictly in the same plane.

Homemade laser devices can hardly be called ideal, but the clarity of the markings applied is very high. Another advantage is that everyone can assemble such a tool with their own hands from the available materials, spending a little money and time on its manufacture.

The laser level is designed to determine the horizontal and vertical lines and planes during the construction of building structures and finishing. With this device, the geometry of the element can be observed with great accuracy. This is important for the strength and durability of the object under construction. But it is not always possible to purchase an industrial device. However, a skilled craftsman is able to create a laser level with his own hands. Consider how to do this, and whether it is possible to repair a broken level at home.

What is a laser level

In the case of this tool, LEDs are installed, which are sources of laser radiation. With the help of a bright luminous line, you can mark up any object both in the horizontal and vertical planes. Moreover, one person can easily cope with this work.

There are three types of lasers:

• prismatic;
• rotary;
• point.

Prism instruments create a linear beam projection. When a luminous line collides with an obstacle, the device captures the data and shows the desired markup. Such levels are equipped with an auto-leveling system, necessary to compensate for errors up to 6 °. The laser beam projection angle does not exceed 120°.

A prism laser level has a short beam range - an average of 10 to 50 m.

The prism laser level allows you to get horizontal and vertical planes that intersect at right angles

Rotary devices are classified as professional tools. They are equipped with point laser devices, but not fixed, but rotating with adjustable frequency. Designed for marking on very large areas, for example, on a construction site. The rotary level can project a 360° plane.

Rotary levels are characterized by a longer range of the laser beam - from 200 to 500 m.

By installing a rotary level in the middle of the room, you can mark all the necessary points around the entire perimeter

The point level is the simplest: the laser device is clearly fixed, and behind it is only a focusing lens. It directs the light flux to one point. Set up the device manually. Such levels are equipped with one or more lasers. In the latter case, they are directed in different directions, which makes it possible to transfer markings from several planes - walls, floors and ceilings of a large area. The laser beam projection angle does not exceed 160°.

The operating range of the point level is from 15 to 50 m, depending on the model.

Compact and versatile point laser for all leveling jobs over short distances

What is the device for?

The purpose of laser devices is diverse. They are required for the following types of work:

• breakdown of the territory and installation of equipment with control of the position horizontally and vertically;
• marking and determining the direction;
• surface leveling of the floor, walls and ceiling;
• arrangement of a concrete screed and assembly of floors with an adjustable level;
• carrying out communication highways;
• installation of bulkheads and hanging accessories;
• installation of stairs.

In the latter case, such an ability of the device as marking inclined planes is used. For example, you need to mount a railing on a flight of stairs. Having fixed a level with a laser on it, it is easier to install the railing parallel to the march.

To understand how to use the level, you can use the example of common construction and repair work.

Leveling floor, wall and ceiling surfaces

When carrying out such work, additional control marks will be needed. Then the laser beam is directed along the plane. According to the marks, the laser is rearranged for a more accurate determination of the evenness of surfaces.

When using a laser level and obtaining the same data, the floor is completely flat

Laying ceramic tiles

For such work, it is better to take a device with the function of cross-projection of rays in the horizontal and vertical. Thanks to them, even a novice master will be able to lay tiles flawlessly.

The intersection of the level lines is set to the center of the intended tile joints

Wallpapering

The gluing process itself is quite easy, but the use of a level allows you to make the process even easier. Focusing on the laser beam projected onto the wall, it is much more convenient to align the wallpaper.

Horizontal projection will contribute to the correct gluing of fillets and borders

Assembly of cabinet furniture

Even if there are even walls in the house, which is a rather infrequent occurrence, the interior can be spoiled by crookedly hung cabinets, shelves and other hanging accessories. And with the help of a laser that creates a circular level line, you will immediately see how to install hanging furniture without distortions.

The horizontal beam of the laser level will help with the installation of curtain rods

redevelopment

The Plane Builder simplifies this process. To determine the exact placement of drywall walls and partition elements, you will need to install the laser so that its projection on the floor, walls and ceiling is a mark for the intended partition.

When installing a metal frame under a plasterboard wall, the laser level is installed on the floor, the beam is directed upwards so that it marks the profile installation line

A simple device can be used outdoors only in cloudy weather or at dusk.

If a lot of external work is expected (digging trenches, laying communication lines, laying the foundation), it is better to get a professional plane builder with a beam visible in sunlight.

How to DIY

The idea of ​​a do-it-yourself laser level is quite simple - the pointer is mounted on a movable platform. The use of such a mechanism allows marking by turning it at the same level by 360 °.

Necessary tools and materials

In addition to the laser pointer, you will need the following supplies:

• glue;
• saw blades for metal;
• jigsaw;
• a piece of corrugated plastic (for example, a headlight from a bicycle).

Walkthrough

You can make a laser level with your own hands from a pointer in just an hour:

1. Let's improve the pointer. We saw off its tip, leaving the threaded part.

   The laser pointer emits a dot

2. From a piece of plastic we cut out a circle with a diameter, like the tip of a laser pointer.

   If you pass a pointer beam through corrugated plastic, you get a line

3. Glue the plastic circle to the tip of the pointer.

   The place of gluing parts can be additionally coated with cold welding and turned

The imperfection of this version of the level is its one-way mobility - only horizontally.

The laser level must be fixed perpendicular to the plane

If you need to markup not only horizontally, but also vertically, you can try to mount a more advanced device:

1. A hole is drilled in a wooden pole so that a long groove is obtained (or a ready-made plastic tube is taken). A pin, bolt or self-tapping screw is inserted into the hole in the center and fixed. The hardware is placed with the head down and fixed with an adhesive.
2. A wide articulated fork is installed on the pin. To prevent it from loosening and scrolling, a rubber gasket is installed between it and the rack. A base made of plastic or wood is placed in the fork. A screw fastener passes through it, fixing the workpiece on both sides of the fork.
3. The building level and an improved pointer are fixed on the base.

This type of assembly allows the device to change the location of the laser in the vertical direction. If you are smart and choose a suitable fork, it is realistic to assemble a device with a vertical turn of 270 °.

It should be borne in mind that the larger the fork size, the wider the workpiece will be required to create a stable position.

This device is collapsible. For the stability of the base, you will need to find a fork with a hinged part of the desired section.

If there is no suitable plug, you can make it yourself from a durable metal-plastic ring of the desired section.

You will need to drill three holes: two from the sides, opposite each other, and the third is exactly in the center between the two future “teeth” of the fork. Then the ring is cut so that a semicircle with three holes is obtained.

A homemade laser can be modified: screw an ordinary nut or “lamb” onto the mounting screw, which allows you to quickly loosen and fix the base, as well as change the direction of the laser up or down.

Setup and Calibration

After assembling a homemade device, you need to set up the laser level with your own hands. It is necessary to check it - to calibrate for the accuracy of measurements. To carry out the test, you will need an additional bubble level. Calibration is carried out as follows:

1. The device is placed in the center of the room and marks are made on opposite walls at the point of intersection of the planes.
2. The level is transferred to one of the walls at a distance of approximately half a meter, another mark is made above or below the first.
3. The device turns to the opposite wall, a mark is made.
4. The distance between the marks on both walls is measured and the error is calculated.

For example, the difference between the marks on the first wall is 4 mm, and on the second - 3 mm. As a result, the error is 1 mm. If it is larger, then the device requires adjustment.

The self-assembled measuring device can be placed on a tripod or adjustable pedestal, which will give the product convenience and functionality.

To calibrate the vertical, mark two points in the vertical plane and check the marks on the bubble level.

If no deviations are noticed, then the plane builder is ready to work. If there is a discrepancy in the readings, a home-made laser device is adjusted by changing the location of the platform or swivel fork.

How to repair

Due to the failure of the laser mechanism, it may show the wrong level or not work at all.

Homemade fixture needs repair:

• in case of diode failure;
• sticking or failure of buttons and switches;
• when the emitter malfunctions, when the laser does not glow or the beam is very dim.

Most often, repair of laser levels is required after the device has been dropped. In this case, the settings are lost, which leads to the issuance of incorrect indicators by the device.

If you need to repair a homemade laser, you need to disassemble the device and reassemble it. If the problem is in the pointer, it is easier to replace it with a new one.

In order to avoid repairing a homemade laser level, it is important to be careful when working with it, especially on the street.

To build even planes on large-scale construction sites, industrial levels with a large operating range have been created. For minor repairs, you can make a laser level with your own hands.
