When carrying out repair and construction work indoors, it is very convenient to use the laser level to build a straight horizontal or vertical line. Just for the sake of 1-2 applications, buying this device does not make sense. Very expensive.
However, there is an alternative - you can do the laser level with your own hands. It will come out much cheaper, and the construction of axes on a plane will cope no worse than a conventional linear laser level. An error, of course, can be, but not critical.
To make this homemade product you will need a Chinese laser flashlight, a piece of profile pipe, an aluminum or steel tube, a small piece of a mirror and an electric motor for 12V. That's the whole set of materials.
The main stages of work
The first step is to cut a piece of aluminum tube that is suitable for the length. Insert a laser flashlight into it and fix it with hot glue. The ends of the tube should be open.
At the next stage, the master cuts off a piece of the profile pipe. On top of the profile you need to glue an aluminum tube with a laser flashlight inside. To do this, it is better to use some kind of two-component adhesive.
In the profile pipe, the master drills a through hole under the motor shaft. Then the motor itself “sits” the glue, as well as the battery and the on / off button. A plastic tube is put on the motor shaft, and a piece of the mirror is attached to it - on hot melt adhesive.
Now the home-made laser level is ready to go. We insert the batteries into the laser flashlight, mount the structure on a tripod or tripod (by the way, they can also be made from improvised materials), set the desired height, and you can make the necessary marks on the wall.
