Every day we use a huge amount of things and have almost ceased to notice them. But it turns out in the production of minor things at first glance hides a lot of interesting and informative. Entertainment “Conveyor MK” reveals the secrets of making the most ordinary things at first glance. Tonight, the BOLTS AND NUTS.
Bench drilling machines (such as NA-10, NA-12), as a rule, is at any station of young technicians in every school workshop. There are some in our school (I work as a teacher). And once a pupil of the 6th class when drilling holes in small parts dropped it in a vise. Began to turn them over to get the detail, didn’t hold, and the grip fell to the floor. Only by sheer luck that this incident was closed with a foot injury, although the consequences for the child could be much more serious. I think that such incidents are not uncommon: in school workshops and at the premises of technical circles often seen on the floor next to astelinastelin press dents from the clutches of the fallen.
In recent years, developers of electronic equipment for ham radio became available to the newest element base of leading foreign and domestic manufacturers, allowing you to create new versions of familiar domestic devices, significantly increasing their performance.
The LEDs are almost all primary colors with a high light output allow to create elegant compact design home night light without using incandescent lamps. The intensity of the luminous flux generated by the described device, it is sufficient that, at least, not straining your eyes to read newspaper text at a distance of two to three meters from the source.
Roof boards are used primarily for stopping stop condensation in roof construction. They can be used as wind barrier elements and additional insulation in the exterior walls of the building. The roof plate is a wood plate with milled edges of the “tongue-groove”, that is with constipation.

In childhood, many have probably experienced the delight of the books of Jules Verne. The romance of traveling on the Nautilus is impossible to forget even after years. Today the submarine with the same for her periscope is of interest to those who in the future will be the captain. For making a simple periscope need not so much – two vanity mirrors (4) about the size of 50×70 mm and thin-walled durable material (e.g., wood or plastic) from which to make the walls of the optic tube (1), which are adjacent the top (2) and bottom (3) of the knee. Them at a 45° angle set of mirrors. In the process of manufacturing the device can be guided to one of the shows the structural schemes. The length of the spotting scope in the 300 – 400 mm can be considered sufficient. The periscope can be equipped with rotary device and handles that will allow you to feel like a real submariner.
It would seem that there is nothing easier, than to hammer in a nail. This can make any boy, not to mention women.

It turns out that this common and seemingly simple process has its rules and peculiarities, which cannot be ignored.
The idea to build a small tractor did not come from “itching” technical creativity and the urgent need for mechanization of the farm and the transportation of economic goods. The last appointment of the tractor vehicle, predetermined the necessity of its registration in bodies of Rostekhnadzor. And therefore just note the following. Although most of the units, mechanisms and assemblies used in tractor from written off cars and agricultural machinery, bought them not as necessary, but strictly according to the documents — bills and receipts that subsequently (at the reception) was brought in the office.
Temporary fence is used often with the reserved area for the Parking or temporary travel restrictions. Installation of fences of this type often solves all the difficulties associated with the Parking of cars.

Attachment points to the supporting plates are reliable and durable. Fixed bollards are mounted using chains for the separation of Parking spaces. They are successfully used as paving portable fencing to mark pedestrian areas.
Folding bike nowadays. However, its dimensions even when folded great, and to keep it at home and even more to transport on the bus or tram is not always convenient.
Moscow engineer I. Sorokin has set a goal to develop a convenient folding bike smallest possible folded size. The outcome was a two-wheeled machine which after the transformation is placed in the bag with the dimensions 650x450x150 mm.
