All you need are a manual air pump, an electric engine, some scrap metal parts and prepare for some welding. Of course, if you can’t weld at all, you can build the compressor frame out of wood, too.
By attaching the pump to the engine with a crank handle and simple reduction gears, you can set it up in no time. Now just get your flat tire or whatever needs air and get cracking.
They guy in the video even uses his compressor for spray painting the back of his car. He just added an old tire as pressure tank in between the pump and his spray nozzle.
That’s some serious do-it-yourself engineering.
