For a long time I enjoyed long ago acquired by manual uniaxial shopping cart (unfortunately, information about the manufacturer not preserved). But remember, in the passport on the cart was given data: load capacity — 25 kg weight — 6.5 kg. the Trolley is made, that is, the conscience, the design is reliable, very simple moves from transport to working position, and it happens that I’m on it loads up to 50 kg, that is twice the nameplate figure. Now it is clear that the manufacturer of the truck was safe and resulted in low capacity, as the possibility of a much larger truck. The developer could specify the actual value of the load capacity, but it was necessary to test truck durability.

PNEUMOCOC IN WINTER AND SUMMER
Downhill on sleigh with mountains-a fascinating sport and a great way to relax. It is a pity that this pleasure is available only in snowy winter. Summer, spring and fall on such a lesson can only dream of. However, it is possible to make and such a versatile sports equipment that is suited for skiing the mountains at any time of the year. Moreover, it is not too difficult. However, “Sani” then you need a special air.
“SNOWMOBILE” IN FIVE MINUTES
You can understand the burning desire of the baby who saw for the first time the competition modelers, asking parents to buy or make him a miniature technique, not postponing it for later when he grows up and goes to a club.
Propose a simple dynamic model will be able to help parents in a similar situation, because it forces to make yourself out of scrap materials, very quickly and most importantly with your child. In such cases the boys could evolve into a love for a fascinating and accessible in this age, the technical creativity — modeling.

PLOW WINCH…
Many rural Amateur designers rightly considered the most promising motoliberty tillage unit. However, it is not without drawbacks. And chief among them is the need every time to drag a heavy plow from the end of the furrow to the beginning, at the same time shifting the very motoliberty a distance equal Majboroda. The fact that in this case the power unit and tillers separated.
AMPHIBIAN ON BED
We present a prototype of the amphibious machine is a device hovercraft (Ohr) under the name “Aerodzhip”, publication of which was in the journal “modelist-Konstruktor” No. 7 for 2007. Like the previous machine, the new machine – a single-engine, single-rotor with distributed air flow. This model is also triple, with the location of the pilot and passengers at the T-scheme: pilot middle front, and passengers – on the sides, back. Although there is nothing stopping the fourth passenger to sit behind the driver – seat length and power rotor setup is enough.
“COPPERBAR” OF “GRINDER”
The device, which I have called “cappenberg”, I constructed at the time when he decided to make an improvised wheels for walking tractor. Wheels with a diameter of 320 mm were cut using this tool.
With a small hand held cutting machine (popularly referred to as “Bulgarian”) model GREAPO PG125SE, made her a simple, but reliable, and most importantly—the right fixture for cutting parts in the form of a circle of sheet metal or holes in it.
3D MODEL OF INTERNAL COMBUSTION ENGINES
A modern car, most often propelled by an internal combustion engine. Such engines there are so many. They differ in volume, number of cylinders, power, speed, fuel used (diesel, gasoline and gas DVS). But, fundamentally, the device of the internal combustion engine, it seems.
