Towing for wheelchair users, skaters and cyclists. vehicles can be divided into motorized and non-motorised. And the second can be transformed into the first by equipping the engine. So at the time of bike get the bike out of the coach — car, tram — tram. But unfortunately, not every non-motorized vehicle can be equipped with internal combustion engine: if you install it on a wheelchair, then it will be impossible to use at home, and be equipped with motor roller skates or roller skis will hardly allow their sizes.

I homebrew with years of experience, have built and snowmobiles, and ATVs. But my biggest passion is boats. Despite today’s gloomy everyday worries, I still find time to do what you love.

As you know, produced by the domestic industry before outboard engines (PLM) was far from perfect. Often craftsmen themselves had to bring them to mind: to reduce weight, increase power, make more economical, reliable and even aesthetically pleasing.

Well the classics! Out beyond the outskirts, in places reserved, the endless expanse, the grass is high, the breeze fresh. All poetic mood adjusts. Here is born: “mow, scythe, while the dew…”, “Razzudis shoulder razmahnis hand…”

Ordinary today’s “urbanizirovan” peasants (and townspeople — the owner of a small land near the house) sometimes to sublime. Mow-to cut grass often in places where neither hand nor with any mechanical scythe, as they say, especially not at first.

The carriage road, and any other bike is perhaps the most loaded mechanism. Therefore, in the carriages with the outer conical bearings at moments of considerable congestion often destroyed bearing cages, often damaged, and ball tracks on the cones of the carriage shaft.

Among all the aircraft of interest to Amateur designers, the most affordable, nairne, gyroplanes. Usually, this simple and relatively cheap machine, because from a purely aviation materials in their manufacture are required, except that dural profiles, and a limited number. The design of such aircraft proposed to the readers of the magazine air force Colonel, retired Professor of a Moscow University p. MERKULOV.

Flying cord “pilotage” — a beautiful sight, equally exciting for the athletes and spectators. Accordingly, among modelers-korovikov the number of adherents of flying is very high. And it could be much higher if not for problems with model aircraft engines. A small resource of internal combustion engines, the difficulty of obtaining fuel mixture, difficulty starting (especially in winter) — all of this contributes to the popularity of cord models with internal combustion engines in General and flight in particular.

The need to build a mini-tractor came to me simultaneously with the acquisition in the early 80-ies of the garden plots (receiving, as they said then). Those coveted six acres it was necessary to develop and sustain. I wanted to build a country house. Without mechanized assistant in this matter to do would be difficult. Industries such machines at that time almost was not allowed to get them even an acquaintance, it was almost impossible unless you’re a war veteran.

The easiest way to cast him “into the ground” — in sand-clay the form obtained by pressing it to the plane of symmetry of the model Bulba, carved out of wood. Bulbs obtained from pairs of such castings, tied in a single whole with three or four screws-tapping screws.

The next stage of construction of the body — bonding of the frame members and the keel well, which under the wooden slats, plywood box and pitching well in the foam cut grooves, and all these details are fixed in the housing with epoxy glue.
