In the process of exploitation of the deep (submersible) pumps often break. To catch them on the outside of the flange for lifting from the well is impossible due to the tight fit of the latter to the well casing. To catch the open borehole pump in the well and pull it out for repair will help homemade trap-hook, mounted on a segment of the rod is square tube. From the version published in the journal “modelist-Konstruktor” No. 2’98, and other analogues of this fixture is distinguished, above all, reliability of operation and ease of use.
LIFEGUARD SUBMERSIBLE PUMPS
Many rural residents who had not previously had the cow, now forced them to start. Because the cow has always helped humans to survive in difficult times, providing it with milk. But the owner should take care of the animal to the cow in the stall period were full. As you know, the main feed cows grass or hay. Unfortunately, the cow while in the stall, not very zealous about his food and in search of delicious blades of grass could easily trample a whole bunch of hay or grass.
In a country HOMESTEAD or farm, however small, any mechanized cargo vehicle can help a lot. It helps to save money and power. Of course, when it is simple and reliable. Preferably, the machine was small in size for maneuverability and had the power (even at the expense of speed). Permeability it should also be on top. Road on not very much welcomes the emergence of these self-made vans on the highway, so their destiny is mostly unpaved country roads. As a rule, on such roads, two clear of the track (after all, they don’t even profile), so they wheeled transportation vehicles (“ants”, power tillers with trailers is the most affordable for most owners) is difficult.
On the roads of Russia today quite a lot of cars of foreign production. To feel confident in dense traffic and domestic car, sometimes you have to reinvent the wheel. Indeed, the idea of supercharging the internal combustion engine to increase its power by increasing the air pressure at the inlet is not new. However, the use of aggregate charge one of the cheapest ways of achieving this goal.
From old books on beekeeping found out that Dadan, which are known even to a beginner beekeeper, as side and ceiling insulation in their hives used mats of straw cutting. I use mats of Chakan, which is usually cut in early winter. The result got rid of the dampness in the hive. But in the spring after the flyby of bees re-make of the case papers. Convinced that Chakan is a great insulation.
It is no accident XII-IX century BC historians call the “dark ages”. During this period, the tribes inhabiting the Northern and Eastern coast of the Mediterranean sea, meeting face-to-face, marked the beginning of numerous clashes peoples. Ancient States were dissolved in the mass of the conquerors, and the free lands of the new colony. Art, and knowledge fell into decay, was perfected as a weapon. In the center of these events was Phoenicia, a city which has turned into a different camp. But not only the fear carried with them the conquerors, has never had the Phoenicians faced with a variety of designs and decoration of ships that washed up on their shores. This was the impetus for the development of shipbuilding. In the main shipyard in the Middle East actively adopt foreign experience, adapted it to new conditions.
The trailer is made in the club “Tourism, and pedal cars”, which I ran for several years. Used in construction sites and technical solutions repeatedly tried and tested in our velomobiles. So the trailer turned out immediately — didn’t even have it, as they say, to bring — and completely met our expectations. To date built five of these trailers, and they all showed a high operational reliability.
Throwing model-polyopia su-24. The model is designed and manufactured in the laboratory aeromodelling Center for children and youth technical creativity of the city of Rybinsk for novice modelers. The prototype has become a modern supersonic bomber with variable geometry (sweep) of the wing su-24, standing in service with the Russian air force. The launch of such models always generate interest among club members, and spectators. And thanks to the simplicity of manufacturing the model of this jet was a great success at the country children’s centres.
Old, seemingly obsolete washing machine— a treasure for zealous owner who loves to make things with their hands. Available it be convenient stainless capacity, small motor AVE-071-4CM (220 V, 180 W, 1350 rpm), ballasts, enough compact body and lots of parts that still can be use. For example, for the solution of many problems of mechanization from the processing of gifts to the garden for fruit juices and vitamin-nutrient mixture to miracle mills with high productivity. Propaganda is the most interesting of these developments, and a lot of attention and my favorite is “modelist-Konstruktor” (see № 12’92, 8’99, 5’2001).
Snowmobile has always been one of the most popular homemade vehicles. The reason is the relative ease of fabrication (the snowmobile has no wheels, complex transmission, hydraulic brakes, clutch, etc.) and efficiency (the larger can on a high speed pass there, where it can crawl except crawler tractors). However, the relative simplicity of design of the vehicle with aerodynamic propulsion introduced many homebrew tempted to create a primitive machine. As a result, these sleds though and could move, but the pleasure of driving the Creator never got them. And most often it was of poor aerodynamic configuration.
