Serpent pilot-glider.The material world around us is continuously changing, enriching all new components, including emerging technical sports. Thus, only in the last decades there has been a Windsurfing and hang gliding, it has become habitual flights in motor gliders, in the snow more often there are fans monoskis-snowboard and young admirers skibord learned to fabricate on their skateboards that were unaccustomed to such a spectacle of man’s best just to squint.
Of course, most men who have garden land or an allotment, there is a walking tractor or tiller, and even Soviet-style — type “Mole”, “Bee”, “Ural”. About them will be discussed.
Usually in the second year of operation of such lawn and gardening equipment after winter storage, there is a problem with starting the engine. And the next seasons of arable happens that stalled during spring work in the greenhouse already and will not start at all!
As in all other life situations, there are certain “internal” reasons.
Unfortunately, problems with electricity occur more often, and there is no guarantee that you will pass this Cup, no matter where you live in the city or in the countryside.
To protect yourself in case of “emergency” situation, it’s best to purchase a diesel mini-power station, but… not all of it is the pleasure afford – the unit itself costs a lot, and even “feed” his need, and “oats now roads.” Another thing – the wind power. It is possible and to do that, and then – save your energy and use when needed. Many prudent owners of summer residences and personal plots do.
Box plywood cap on the radiator with a pull-out slatted frame will double the useful work: quick dry hanging wet towels or nappies and simultaneously to humidify the air in the room, which is very important for health.
The journal “modelist-Konstruktor”, according to my calculations, for a long time can already be entered in the “Guinness Book of world records” for number of published articles on homemade from plastic bottles. Why not just made them attentive readers! Glasses and sockets for jam, glasses and shades, galoshes and beach mattresses, funnels and megaphones, rotary vane and hull models of yachts, hydropneumatic rockets and mentality cylinders under compressed air for aircraft with pneumatic actuators and decorative candle holders.
From the futuristic Android turn to more practical developments.
A few days ago Boston Dynamics, creators of the infamous Big Dog, posted a video on his other project – Petman. Previously, it wrote, but then development was very raw and what is shown now is really impressive.
The essence of the method of investment casting is that the model is made from such a material without destruction of the form, you can melt or dissolve and get all-in-one form, which ensures high accuracy of castings. Most often, the material model is legkodymova waxy mass. The investment casting get casting of complex configuration with a wall thickness of up to 0.5 mm, mainly from steel and heat-resistant alloys, hard processed mechanically.
To travel by a caravan – all the same, that to have my own Motel on wheels. In contrast to vans, trailers clinging to the car, and have the stuffing from the simplest to the most luxurious including a fully equipped bathroom and kitchen.
To make the caravan, the workers erect a frame of steel beams. The saw, which cut them, water cooler, so it does not overheat during severe friction. Do then in the joists, screw holes and screws to fasten components. The beams are then welded to the working craftsmen in the finished frame. Around the frame is passed an electric wire; the holes where prophet wiring, edging, rubber-insulated in order to prevent damage to the sharp metal edges of the hole.
For the proposed universal physical campus, classes designed for both teenagers and adults, just a small free site (dimensions 5×5 m), where you can install 8 — 15 shells made independently from abundant materials (waste tires, dismantled metal pipes, rails, concrete pillars, scraps of cables).
In this town the shells, it is preferable to place the compact that will enhance the effectiveness of training, will relieve us of unnecessary trampling of green areas. Around the site it is advisable to plant a hedge of trees and shrubs that will create additional facilities for training, the greens will have a positive psychological impact on dealing, protects from sun, wind and dust.
In the conditions of a home workshop without special tools and fixtures can be performed, perhaps, only the so-called “collective” keyway: when impaled on the shaft gear or pulley is drilled by the drill joint hole centered on the circle stitching. Then in this hole is inserted a cylindrical key. But such a connection of the parts securely — no wonder because it is not in any Guest.
