SKI OR CATAMARAN?

SKIS OR A CATAMARAN?The boats, which we would like to introduce to the readers, it can be attributed to the category of small vessels. And how else to call a couple of universal self-propelled floats, which are easy to use and as gidroliz, and double pleasure catamaran. As can be seen from the drawings, each of the floats is a miniature boat with a power unit including battery, motor and propeller. Displacement of one float is about 140 kg, which allows not only to equip its power plant, but also allows for “skier” when you need to rely only on a single float, not fearing that he will go under water.

MINI-JEEP: PULL, NOT PUSH!

The vehicles of the “jeep” has always attracted Amateur by automakers its pronounced functionality: as they say, a jeep is a machine “advantage.” And, of course, the plainness of the external forms and the complete absence of surfaces with double curvature — and therefore, easy manufacturing of the body from any sheet material, ample inner space. In short, the machine with the appearance of the jeep will always be preferable for those who starts creating his very first vehicle. It was decided to develop a car like the jeep. However, the portrayal of the machine was that the plainness of its external forms is only apparent, and create a truly original body is very, very difficult. All of my “designer” refinements led eventually to the appearance of the paper machine is clearly artisanal. In the end had to turn to classical models by taking as a basis the famous “jeep” of the forties. In fact, I do, in General, a layman in design, to compete with the professionals who created a kind of reference appearance of this vehicle.

AIRBOAT: SCHOOL, SPEED

In modern modeling design aerovision championship-class technologies have gone far ahead, and currently only a handful of athletes capable of creating competitive devices. In the conditions of the road and at home to make the modern model of the average Amateur athlete is very difficult. Practice runs aerolizer and the engine (especially if you have a part in competitions of any rank — from vnutritrekovye to on) on “fighting” techniques are not always appropriate. However, the experience and the ability to absorb necessary. To have technique training “for all sluchai”, but is simple to manufacture and launch, I had to think carefully about possible options.

FROM FLASHLIGHT INTO A FLOAT

FROM THE FLASHLIGHT TO FLOATMany are addicted to fishing for them this activity is a fascinating vacation. The very same UDA, rod, adise is one of the oldest fishing gear; by definition of V. I. dal’s dictionary, it is “spun horsehair forests, with one (or more) hook, which is sometimes linked to special powada; hook is attached above the sinker, above, depending on the depth, the float, the upper end attached to the rod, the shaky stick”. However, progress is inexorable. To replace the forest horsehair came nylon fishing line, floats of nylon and become electrified. Improving manual fishing gears and devoted this article.

You will agree that even in a darkened cellar will not mix banks, for example, blueberry and blackcurrant, if they have labels with information about the contents. Someone as label uses paper someone a band-aid. I take a transparent adhesive tape (“Scotch”), enclose under it a narrow paper strip with an inscription, say, “Blueberries, mashed Read more…

BED: AND THE SHELL, AND SPRING

In many homes, especially in rural areas, and in the cottages, too, remained not long ago, the popular and favorite due to its “softness” a bed with tubular grid. Indeed, they “rest” — how the cloud fluffy, and dreams are seen the same pleasant, light. And that they gradually disappeared from our daily lives, do not blame the mod. Just over time, the tubular mesh is stretched and after a few years turned into a kind of hammock in which to sleep was not comfortable tan as before. I managed without much parentage to return this bed to its former comfort by combining after modernization, the benefits of the “shell” and the usual cushion springs. It took only two solid boards and some coil springs from an old sofa.

HEAVY TANK is-7 (“object 260”)

HEAVY TANK is-7 (In the postwar period the plans for the organization of our armored forces military experts associated primarily with the latest heavy tank is-3. Commercially the tank was produced at the Chelyabinsk Kirov plant in 1945-1946 very fast pace. So, in the summer 1945 issue was, for example, 250 items per month. There were manufactured 2305 machines.

However, in the beginning of the service in the army revealed a number of fundamental flaws. The fact that many of the mechanisms and units, the is-3 proved to be unsuitable for prolonged use in peacetime because of the very low reliability. Apparently, affected the calculation of the short military life of machinery, which lasted in combat just a few weeks. Therefore, after 1948, they were subjected to alteration and modernization program of eliminating design flaws at the same Kirov factory in Chelyabinsk.

ON THE “TRAMP” – IN CYCLING

Categories Design

Our family vehicle — a three-wheeled velotandem “the Vagabond” — designed by me for tours. From the same konstruktsii it is distinguished by the absence of any irreversible modifications to the basic bike on the basis of which created velotandem; ease of fabrication of additional parts and components which couple to the standard model turns into a three-wheeled trailer, as well as high reliability “Tramp” tested tough operation on the roads of Russia.
Like all tandems, our also has a smaller in comparison with a pair of conventional bicycles CX — the drag coefficient and, as a consequence, a lower sensitivity to the counter air flow. All of this allows easily for 4…5 hours to maintain a cruising speed of about 20 km/h (7 km/h uphill and 80 km/h on Sunnah). To resume movement, as experience has shown, it only takes two or three hours of rest, although the crew does not have high athletic qualities.
