At the time of making this simple craft, even the name of which is hard to find: “whether the junk, or boat, or boat, or raft”, I had a “Kazanka” boat is roomy, durable. However, it was intended for sailing with an outboard motor. But what, say, fishing in a quiet backwater after it came a motor boat. To walk on the oars “Kazanka” too heavy and unwieldy. Shipping it to the waters too troublesome to do without the trailer and the assistant was not possible.
Well-known model electric fibroelastic inherent drawbacks: on the table crawl, hands from the constant tension when working with the machine buzzing… to cut delicate items, should be thoroughly accustomed. But if broken flat spring near the nail, there arises a problem of their repair. But the vibrating base, remaining out of work, can be used!
Anyone who self built a house, garage, cottage, etc., knows that the most difficult stage — zero cycle (the Foundation) associated with the preparation of a large number of concrete mix or mortar. Of course, if you have a mixer, then everything is easier and simpler. But to buy such an expensive setup for short-term use is expensive and knead with a shovel in the trough is not very desirable. Way to make the mixer itself. In the “Modeller-designer” there have been several publications on this topic.
History of rocketry in our country today is widely reported in the local media. In my opinion, it is interesting it is stated in the book “Rockets and people” – B. E. Chertok (Publishing house “RTSoft”, 2006) – a direct participant in the whole period of the birth of rocket and space technology. These books “pushed” our children-rocketmodeler to implement the idea: to recreate the models in the basic steps of creating missiles and combat shield of the Fatherland and the achievements in space technology. This project was a contribution of students in the Year of Russian cosmonautics and the 50th anniversary of space flight by Yuri Gagarin.
The greenhouse is hardly surprising. As in the days of V. dal, compiler of dictionary of the living great Russian, it’s all familiar “hothouse without the furnace; dug-in srubar, a box of manure and black soil, indoor removable Windows for Virasana early greens, vegetables or fruit, loving the heat”. Keeping the overall features of its numerous analogues, greenhouse and received recognition from the members of our garden co-op has substantial differences. This excavation shed design that runs on biofuel and is equipped with mechanical system avtobronetehnika. As a “removable Windows” used house the sashes, the Central one of which – with opening transom or large window.
There are many different tools, devices, equipment, value of which is primarily determined practical purpose, and their appearance and technical aesthetics are of secondary importance. I think that applies to them and of garden sprayer machine, which sprayed pesticides against pests of plants. If you have at least a small locksmith skills, then make a sprayer you can own from a suitable container. The principle of operation and technical parameters (capacity, performance etc.) it differs little from those offered by industry.
Agile, compact vehicle is vital, especially in the snowy and wooded areas. In some countries, for example, in the US, Canada, Japan, this problem is solved by the small-scale production of cars type motoart. Our industry has also begun to issue such equipment: there motonarty “Buran”, Amurets and others. However, these machines are more for entertainment, they have not even insulated the cab.
It is possible to invent in all spheres of human activity. And agriculture is no exception. It is known that potatoes are best grown in sandy soil: and plant it well and harvest easy to mechanize. Well, if the soil is solid clay, weather – rain, rain, revocable, and agricultural equipment available? Grow crops in this case, the farmer helps his fiction. To trace the course of thought of the inventor, as a rule, difficult. But by and large, useless. Much more important is the result of the thinking process. In the case of potatoes, in relation to my humble experience since 1991, it can be so.
For chemical protection of agricultural crops from pests and diseases, and in making micronutrients during weeding chemicals are usually converted into coarse aerosol, which is directed to plants or soil. At the same time seeking to labor costs were minimal, and spraying the preparations were used, if possible, without losses. And fractional composition of the droplets, the content of active substances try to make optimal.
Have in the farm or on a personal farmstead of a good high-performance kruporushka not a fad, but rather a vital necessity. Especially when you consider the high cost of ready to “purchase” animal feed and often inconsistent quality of the advertised. However, some specific designs of existing diversity of shredders (including home-made developments, published at different times in the journal “modelist-Konstruktor”) to choose?
