Say, in the Urals during the difficult years of chaos after the civil war an artificer built a car where everything was wooden, even the engine. However, if the wizard so the echo legendary as Leskov’s Levsha, here the use of wood instead of metal in the most important nodes in modern machinery: rolling mills, tractors, cranes, harvesters — not a legend, but a reality of our days.WOOD ENGINEERING
Say, in the Urals during the difficult years of chaos after the civil war an artificer built a car where everything was wooden, even the engine. However, if the wizard so the echo legendary as Leskov’s Levsha, here the use of wood instead of metal in the most important nodes in modern machinery: rolling mills, tractors, cranes, harvesters — not a legend, but a reality of our days.
The idea is to make two-cylinder engine came to us with the son, that is, from want. In times of General scarcity in the economy was necessary for some vehicles to have the house and farmstead to provide those without something to exist person in the Russian hinterland is simply impossible. This is the wood, hay, building materials, which had to bring. Plowing and treatment of the infield in the required quantities without the technology, too, was unbearable.
The article “Acupuncture for metal”, published in the journal “modelist-Konstruktor” No. 2, 1974, provoked numerous responses, not only individual readers, but also many businesses and organizations. Editorial Board, ENEA USSR and VNIIST continue to receive letters and inquiries on the subject.

SMALL SPOOL, BUT PRECIOUS!
A simple design of the airframe suggested that the German model airplanes G. Jung and C. Rosa (Fig. 1). The model has good performance and can be built athletes having small practical experience.
Ask any kid, building the first schematic model of what he wants Almost certainly he will answer — about copy. And it is clear. It’s no wonder it is believed that the replica model is one of the most interesting and complex classes of aircraft modeling. Order copies, model airplanes acquainted with the technical achievements of aviation, possess the perfect use of the tool.
The car was conceived and executed as a valid simulator for the novice driver — my 15-year-old son Maxim that he could get it driving skills, and also to assemble-disassemble and repair the machine, mastering the technical “ABC”.
THE DEVELOPMENT OF COMMON TECHNICAL REQUIREMENTS
At this stage of the work, outline the design of the actuator, which provides translational movement of the model. Let’s start with the analysis of the already known mechanisms, which are used in a large technique (Fig. 1). Under the terms of our problem, the most acceptable is the idea of using the wheel.
