The video shows a person creating a DIY concrete mixer using a 200-liter barrel and various spare parts. They begin by cutting the barrel to the desired height, creating a rim, and welding a profile pipe to strengthen the bottom. They then attach a classic car rim, add a pulley system, and install a washing machine engine to power the mixer. The person also creates a custom shaft and bearings, and adds a V-belt to connect the engine to the mixer.
After assembling the mixer, they test it and find that the revolutions are too high, so they make adjustments to the pulley system and add a new keyway. They also create custom blades for the mixer using round timber and welding.
The finished mixer is then painted and wired, with a start button and capacitor. The person notes that the mixer works quietly and efficiently, but mentions some drawbacks, such as the speed of rotation and curvature of the neck. However, they are overall pleased with the device and find it useful for mixing large volumes of concrete.
