Machines have an irresistible attraction to many men, especially those made by hand. A model enthusiast from Spain hand-built a mini engine. This machine has 32 cylinders, used a total of 850 parts and 632 screws, and was only 1 foot long. It took 2520 hours to complete. From the video introduction, we can see that the engine is very precise, and the parts fit perfectly together. After starting, it runs very smoothly, and it will not fall down even if a vertical coin is placed on it. Without further ado, let’s enjoy this fascinating assembly process.
