Before copiers that manufacture aircraft models in the Mel scale, often raises the problem of simulating a power plant with a radial engine. Offers an unusual method based on the use of… conventional steel screws or bolts. First, you need to pick up screws with fine or medium threads, the outside diameter corresponding to the cylinder size of the engine. The screws are trimmed to length and with one edge sharpened needle files tapered tetrahedron (the angle and depends only on the number of cylinders). Then, treating the sharpened surface etched with acid, they oblizyvaet using a soldering iron.
THE MOTOR OUT…NAILS AND SCREWS
Practice starts in the competition boat-“bramahadev” convincing evidence that until today the question of establishing a simple and reliable device for shutdown of main engines after completing the scoring of the race remains open. That is the problem and is dedicated to offer modelers the material.
Even perfectly executed a valid copy of a military ship or self-propelled artillery loses much if its design does not allow to simulate the use of the main weapon of the prototype. But most known simulators does not provide the sound similarities with a shot or hampered their placement.
Preparation for the winter vegetables, fruits and berries in many cases, connected with great inconvenience due to the imperfections of technology and primitiveness kitchen appliances for the job. I would like to offer home hosts a very simple device that helps to simplify and even to protect their work. Let me remind you a bit of a process. Filling vegetables. for example tomatoes, 3-liter jar, pour boiling water over them. After enduring for some time, the hot water is drained.
