Description a three-wheeled tandem, published in issue No. 3, 1979, I liked inherent in it the idea to tandem bike of the usual single, without making major changes to the original design. But the proposed version was not very satisfied: still frame of the second bike had undergone the unwanted interference. I wanted to find a way of articulation, that when there is no need to tandem it was possible to restore the bike to original form.
What started karting? In the 30-ies very popular among American boys was competition for non-motorised trolleys moving along slant paths. Some Joker aptly called them “racing soap boxes.” And not without reason. The first truck actually had instead of the body wooden box, attached the wheels, instead steering was a rope connected to the ends of the front axle. Over time, the “racing soap boxes” has gained the rank of all-American Championships, which often have become well designed and carefully made by non-motorised carriages. But their name lived for a long time.
To facilitate the screwing of the screws in the wooden part or wall of the tube made a simple device — a small gimlet, and doing some preliminary socket-deepening. Here is it the screw even by hand easily screwed in a few turns — then we can tighten it with a screwdriver. By the way, Read more…
Passenger car GAZ-A. Many people know the famous saying of the Patriarch of the American car industry Henry Ford — “the Buyer is entitled to choose a car of any colour provided that its color will be black.” However, not everyone knows that the Ford-T was painted black not because of the aesthetic preferences of the Ford to the Kohler. The reason for this was purely technological — Assembly-line production with its rigid rhythm were taken for drying the body after painting a certain, very short time, which in the early XX century was granted only black Japanese quick-drying enamel…
Agree to see ka road in the evening time the cyclist is not easy, even if the two-wheeled machine and is equipped with reflectors-reflectors. Especially fraught with danger moments braking — braking road bike is relatively small. Conclusion: non-motorized transport are needed now stop the signal.
This unusual hand tool created by the innovators of the Volgograd plant of oil engineering. Pliers designed for flaring pipe lubrication systems and hydraulic control of various machines and machine tools. Simple in design, they at least shorten the time and simplify the technology of flaring. The body of the pliers consists of two hinged halves on their joints in the center holes Ø16 mm.
Many motorists, especially the owners of domestic vehicles has experienced all the “charms” winter operation “beloved horses”. Special “pleasure” — after frosty nights to bring to life the heart — the powerhouse. I have a giant of Russian car industry — “Eye”, so all my thoughts and efforts were directed to develop a system that allows you to quickly and efficiently prepare the engine to start, warm up underhood space. respectively, the battery and create, if possible, a comfortable environment in the vehicle. The advantages of such training are obvious: easier to start engine at any temperature; reducing consumption of gasoline at start-up and engine warming up, which is especially great in the cold season; increases battery life by reducing the starting current on a warm engine, increase the service life of the starter by reducing the wear on the bushings the armature and the life of the engine.
Scoop for garbage collection — it would seem that can be easier. But no, in this elementary product their problems. In stores sold plastic shovels (one-piece) and with a metal bucket and wooden handle. And those and others to be unreliable: break on the bridge at the junction of the handle with the vertical rear wall of the bucket. Is inadvertently pressed a little harder to scoop semi — Yves plastic crack is formed, and a metal jumper — plastic deformation. Over time, the defects accumulate, and the result is failure.
Universal control line model aircraft. The design “Teardrop” models for air combat — have occurred in several stages. In fact, immediately, in one step to create obedient to the pilot model was not possible, believe me, anybody. As a rule, first designed and built a simplified model, which practiced its concept, geometric parameters, the controllability and stability of the flight. Further, according to the results of test flights made necessary modifications, and then creates a second version of the model in which the basis is all the best from the first. Sometimes the model is good, but often for the second stage follows the third…
This cartoon is unlikely that today someone does not know. And it can be noticed even because of catastrophically decadent state of modern animation channels for profit have found ways to get round care for children-time scoring esters of the old Soviet cartoons or Czech cartoon series.
