On the shelves of sports stores you can often see elegant double sledge for skiing the mountains, called “Chuk and GEK”. The sleds solidly constructed, brightly colored, very attractive in appearance, but… do not use special demand. We do not undertake to judge how good these sleds, what their shop offers, but after the installation of vasodilates D-5 and they, undoubtedly, will be a very interesting self-propelled machine (Fig. 1). Such a construction was offered by a famous Leningrad artist — N. Abramov. In our opinion, the use of sledge “Chuk and GEK” as a basis for creating various children’s trails in machine — sensible initiative. It should be noted that the possibility of their “motorization” is not limited to the offer, which did N. Abramov: in addition to wheel with spikes, can be applied to the screw or the propeller (in the latter case, it will microaerobic). Finally, why not try it instead of the internal combustion engine to set the motor power cable or contact wire?
“CHUK AND GEK” — SNOWMOBILE
Has long been a regular reader and subscriber of the journal “modelist-Konstruktor”. I want to share one interesting result of technical creativity. Sometimes people ask for a drawing apparatus, a photo of which is posted in social networks is decided and for this reason also more to say about it.
What kind of “aerobatics” not started accidentally discharged the cargo to be hoisted, it will reliably keep a simple but effective lifting device, manufactured by the Leningrad pioneer D. Potemkin. The device consists of a loop sling and guide the rifle with a basic platform and hook. A sling is passed between the replaceable pin of the rifle, grabs the goods at the place of the intended center of gravity and jumped on the hook.
If the village is unthinkable without the tens and hundreds of motorcycles, mopeds and bicycles, in the Northern part of the country, where winter lasts nine months of the year, the role of these public vehicles is increasingly performed motonarty. Without waiting for the industry will be able to meet the needs of northerners, many lovers of the snowmobile technicians design and make your metal samples, sometimes not inferior to industrial.
The first development, which we publish, is a universal glider of class “Standard”, called “pennant-4”. Characteristics, it is approaching to widespread machine “Brazil”, but has a number of original nodes, that facilitate and accelerate Assembly and disassembly. The device has been extensively tested in various flight conditions. His flight main advantages: the minimum gliding angle, extended speed range, the ability to execute turns of small radius on all speed range, softness, and ease of management.
No one is surprised that for drilling different holes require different tools. The bit set can not do, does not matter. The trouble is that the tool change takes a lot of precious minutes. How to avoid this! In various companies are innovators in different ways solve this problem. There was, for example, drill bits with a stepped diameter, one such tool allows you to drill small and large holes. And where this range should be really very great work on the turret with permanently fixed at their range of drills.
