THE SHEARERS, NOT ONLY

Shearing machines МСУ200 with a built-in handle three-phase asynchronous motor (200 Hz, 36 V, 100 W, 12, OOO rpm) we have in the village is not uncommon. Though slightly modified, with a reinforcing grommet for the power cable. This technique is popular in neighboring areas, where used by shearers of sheep and camels, as well as professionals postconservatism skins Karakul smusic. As a full-time source of electricity for it is a three-phase network with voltage of 380 V, which МСУ200 connected through electric machines-nye converters ИЭ9401А and ИЭ9403.

IN FLIGHT IN THE GYROPLANE

Who as a child dreamed of becoming a pilot, the conqueror of the fifth — the ocean air! A romantic nature will not abandon his dreams and in adulthood. And they can implement it: currently there is a wide variety of aircraft, which can fly even Amateur pilots. But, unfortunately, if these devices are prefabricated and offered for sale, the cost of them so high that most of them are practically inaccessible.

TRICYCLE-AIR SUSPENSION

A prototype of the proposed tricycle car was made by me on the basis of the motorcycle “IZH” chamber with two leading wheels and a steering ski. It seemed that the desired result is achieved: the machine ran well on the snowy road. True ski on Packed snow bad coped with its task. Spring revealed other shortcomings of this design. Riding on the roads in the thawed disabled even ski in stainless steel. Instead, I put the pneumatic chamber from 12.00—18,” but now more heavily affected by the lack of differential lock — a snowmobile was very difficult to manage.

CRANE MOTORIST

The owners of cars often have to be transported in the trunk of the massive thing. If no helper, then alone to ship them in the trunk or unload pretty hard.

Previously, I also had to strain with a tiller that weighs 55 kg. Now loading-you load, not a problem for me — I made myself for these purposes a special device. It is clear that it can be used not only for the cultivator.

HOMEMADE AUTOCLAVE

Real benign stew without autoclave do not like, however, and other canned goods. However, the production of inexpensive home-autoclaves our industry, it seems, a long time will not be adjusted. Imported equipment, most people can not afford. Has to settle for a canned food factory production. But why not make the autoclave with his own hands? As a basis we can take the industrial analogues or the development of Amateur designers (for example, mini-mill V. Starostina, published in the journal “modelist-Konstruktor” No. 4, 1998). You can use my design, which I think is more reliable and productive.

… CART LIFE

Twenty-first century, of course, not age of animal (horse) transport. However, for those who live in rural areas where there are no gas stations for many miles around, this all-terrain and all-season transport still remains vital and relevant. You would have to say that the view of vehicles – environmental, but in rural areas it is not very important. Although it is worth noting that as a result of work are not harmful emissions into the atmosphere (for example, as from automobiles) and useful – to the soil.

WITH IRON — ON APIARY

Going to put the hives in your apiary improvised electronic thermostat — you will not regret. Because it is simple, in General, the device will create for bee colonies conditions, like the comfort, the economic feasibility of which has been repeatedly pointed out, and the magazine “modelist-Konstruktor” (see for example, №10’93, 12’96, 1’2000). The use of a controller leads to decrease almost two times the previous costs feed — sugar or honey because the bees do not have to spend energy to maintain the desired temperature.

ROCKET FROM THE SPORTING PAST

a Spectacular high-speed radio-controlled model-polyopia missile boats based on the hull of the sports racing model, has been one of the trends of creation of ships with dynamic principles of maintenance, the moving in partial planing. For such ships ostroslovy distinctive lines and a constant deadrise of the aft part of the hull.

COMPACT GEARBOX — PNEUMATIC

27.05.201813.05.2018Design

Pneumatic large diameter low pressure tyres are good drivers of all-terrain vehicles in even the harshest of road conditions. But, working with modern highspeed engines, they require a significant decrease in angular velocity by means of transmission and, consequently, increasing the number of stages of the power transmission, its weight and dimensions. Every Amateur designer in his own way links the transmission. Some are even from multiple gearboxes, linking them together with chain transmission that makes power transmission and cumbersome and unreliable in operation.

VENTILATION IN THE GARAGE

The garage, which was built in the time of my neighbors, so appealed to me that his project was taking advantage of me. Considering his opportunities, the need for ventilation and fire safety requirements, introduced the necessary adjustments. It turned out well.

Around the garage made a blind area and drainage ditch. Along all walls except for the facade, planted low-growing shrubs and trees so they do not interfere with blowing of the roof by the wind and, of course, the air in the garage.
