The Bulgarian is the most "folk" instrument. And not only because it allows you to perform a wide range of tasks: from cutting metal to sanding wood.
The angle grinder is still very often used to make various homemade tools.
In some cases, the grinder acts as a drive (that is, it is used entirely). In others, only its parts are required.
If you don't have a hand router, you can easily make it from a conventional grinder. Read a detailed review of homemade products here.
In this review, we want to share with you the coolest tools made from a grinder. Sit back - it will be interesting.
Usually, cutting machines are made on the basis of a grinder. There are a dime a dozen such homemade products on the Internet. There are also many ideas on this topic on our site, and we will not repeat ourselves.
But the sheet metal wheel cutting machine is a really cool idea.
With the help of a homemade device, you can cut circles of different diameters. Quick and easy. In general, the homemade product definitely deserves your attention.
Today, about fifty Russian-made fighters fly in US airspace - from the outdated MIG-15 to the modern MIG-29. Most of them were acquired on the open market after the collapse of the Soviet Union and the termination of the Warsaw Pact. In Soviet times, the Americans did not have a chance to acquire our combat vehicles, although the States were ready to do anything for this.
On September 6, 1976, an emergency occurred: during a training flight at one of the Far Eastern airfields in Primorye, Senior Lieutenant Viktor Belenko took off in an ultramodern MiG-25, and did not return to base.
The MIG-25 was not a simple plane, but the real pride of Soviet engineers. The high-altitude fighter-interceptor, according to NATO classification, was called the Flying Fox. In the West, this aircraft was attributed with unique characteristics, but there was no way to test their capabilities: the Soviet Union knew how to keep its secrets.
They did not believe in Belenko's escape for a long time: they hoped that there was a breakdown, a technical error, or the plane got into a zone of poor visibility and could go off course. The search for the pilot was interrupted by a call from the Japanese Foreign Ministry. The Soviet commanders were informed that Belenko had landed at Hakodate airport on the island of Hokkaido and asked for political asylum in the United States.
But what really happened?
Viktor Belenko was born in Nalchik, on February 15, 1947, in a working-class family. In 1965 he graduated from high school with a silver medal. In 1967 he entered the Armavir Higher Military Aviation School of Pilots, from which he graduated in 1971. He was sent to serve as an instructor pilot at the Stavropol Higher Military Aviation School of Pilots and Navigators.
He was positively characterized in his service characteristics and certifications throughout his service in the army. Member of the CPSU. Was elected a member of the Komsomol and party bureaus. In 1975 he was transferred to the Far East (at his request) and was assigned to the 530th Fighter Aviation Regiment of the 11th Separate Air Defense Army (Chuguevsky District of the Primorsky Territory) as a senior pilot. He flew a MiG-25P fighter-interceptor.
September 6, 1976 at 6:45 am Belenko took off from the Sokolovka airfield (near the village of Sokolovka, near the Chuguevka regional center) to perform a flight exercise. At 7:40 am, the fighter flew over the Soviet-Japanese border. At 9:15 am, Japanese radio broadcast that a MiG-25P aircraft (tail number "31"), piloted by the Soviet pilot Belenko, had landed at Hakodate airport (Hokkaido island). Subsequently, the Japanese authorities issued an official notification that Belenko had applied for political asylum. On September 9, he was taken to the United States.
After falling behind the leader of the pair, Belenko dropped to a height of about 30 meters, which allowed him to avoid detection by both Soviet and Japanese radars. Deeper into Japanese airspace, Belenko climbed to an altitude of about 6,000 m and was spotted by Japanese air defense systems. The Japanese failed to contact Belenko, since the MiG-25 radio was tuned to a different frequency. Fighters were raised to intercept the unknown intruder, however, by the time of their appearance, Belenko again descended and disappeared from the radar. Belenko planned to land at the Chitose airbase, but due to lack of fuel he was forced to land at the nearest airfield, which turned out to be Hakodate. Due to the insufficient length of the Hakodate runway, the MiG-25 rolled out of the strip and approached the border of the airport territory. Having got out of the cab, Belenko fired two warning shots from a pistol - motorists on a nearby highway were photographing what was happening.
