No short supply differential or planetary rotation mechanism, able to somedelicious nor difficult to manufacture the overrunning clutches is not required for the mini tractor (MT). The torque here is transmitted to each of the drive wheels regardless of their… of the motor. Moreover, the design of the machine is that allows you to change the ground clearance and track.
Judging by the letters received from our readers, many are passionate about creating copies of ships relished compilation copyright materials that reveal various secrets of working on microcode. Today we introduce modelers with experience A. Krainov. THE COPYING SCALE. In the XVII—XVIII centuries, when the craftsmen of that time were created many surviving to the present day models of sailing ships, there was developed a scale based on calculating dimensions in feet and inches. The tradition of the choice of scale has passed through the centuries, and today the most successful I must admit 1:32 and 1:4B. The thing is that in accordance with the laws of copying all the elements of the model should be made of the same materials as those used on the ship prototype. And details such as the shape of the ornament, sculptural elements and other details of sailing ships, when smaller scales cut out of wood or bone is extremely difficult.
To join automodelismo the summer holidays will help is quite simple and yet quite successful design of a sports car. Created in Leningrad by modelers, it has proven to be promising for wide use in the self-similar circles pioneer camps, clubs of technical creativity in the community and at home.
Student design Bureau of Moscow Institute of civil aviation engineers have long occupied a leading position in the design, construction and research of trikes in porridge country. In the “M-K” has repeatedly published materials activities of SKB MIIGA; the last of them (“del’talet becomes a profession”, “M-K” No. 4, 1990| caused a surge of reader interest to the student KB.
Where to start! This is the question asked by many novice rocketmodeler. What model to choose and what technology to build it! In our opinion, a good help in this will have material prepared at the request of the editors by S. Karasinym, supervisor of the club Houses of children’s creativity on Vasilevsky island of St. Petersburg.
Doing for a long time, the construction and operation of velomobiles (was a prize winner of all-Union velofestivalya in šiauliai), I was convinced of their lack of practicality. The large size of the velomobile exclude the possibility of its storage in the apartment. Known foldable construction is complicated to manufacture and quite cumbersome. Used them on wheels, usually a Bicycle, not designed for the lateral loads experienced by the velomobiles on the bends.
When developing this design car trunk, the task was to create a device which, in addition to the normal daily functions would satisfy and lover of outdoor activities — would allow us to transport two sets of boards sailing in the summer and (with minor changes) 5-6 pairs of skis in the winter.
They say everything old is new again. And energy here, it seems, is no exception. Burned on Chernobyl, faced in some places with the threat of an energy crisis, mankind increasingly turns its gaze on technical solutions, unfairly written off in the past in the archive. The use of the gratuitous forces of the wind among such solutions. Come to them in their creative pursuits and like to make things with their hands (see, for example, “M-K” № 4/84, 5/86, 6/90, 7/92|.
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.
