My good friend since high school, enthusiastically collected stamps, matchbox labels, pocket calendars. Now his collection continues to children, and himself, he left only one passion: icons. And store came up with the original book, which makes itself as their collection. Material for their production is either thin cardboard or even paper.
Every time the whole family going on vacation, my task is to check the status of our bikes. As a rule, all the nodes are in order except for the tyres: they require periodic pumping. Here is sometimes hard, and much time is spent on it.
It was necessary to invent a device that would replace the pump. Its main components were borrowed from me… homemade siphon for aerating the water. The operation of the device is very simple. Carbon dioxide gets inside, it evaporates, creating a pressure that the tires necessary.
During the construction of the models is often necessary to apply a veneer of varying thickness. Typically the desired thickness is obtained by grinding with fungus with glued on end cloth, is inserted in the Chuck of the drilling machine. This method is most affordable, but it has several drawbacks: poor performance, inability to process veneer with thickness less than 0.5 mm, because of the rotation of the fungus veneer escapes from the hands and broken, and finally, the main drawback is the large air pollution wood dust. To handle more than three or four plates is not possible even a respirator.
I was lucky in my youth – got into the stream the student of camp life.
On the wave of rapid development among teachers mountain sport trips in our Kurgan machine-building Institute among students have formed groups more accessible pedestrian-“the plains” of tourism.
Within these new groups, which turned out to be and I bubbled its predpechatnaya social life. Everyone found a job interests and abilities. The head of the planned route. The caretaker was a list of products and estimated their cost. Sports organizer spent training and hikes of the day off. The girls wrote songs and was decorated by Gen. And I am a fan of tinkering, came up with a design: tents, windjackets, backpacks & bags camping equipment. Sewed them myself, and attracted to the work of other group members.
Any front panel aluminum alloy easy to decorative treatment. For example, after drilling holes in them you can first put these parts can be anodized, and then painted. Both processes require no special equipment and can easily be made at home.
A small panel anodize in a glass cuvette. It pour distilled water and add 200 ml of technical sulfuric acid for every 800 ml of water. The panel is clamped with the ends of the U-shaped brackets and dipped into the electrolyte. Above it, on hangers, a dural plate-electrode (this may be the second antirhea panel).
Large sibelectroterm plants from time to time organize specialized exhibitions, where to study avenues its primary products are making their drawings. Among other things come across the description and drawings of a variety of original furniture. This is done in order to interest the buyers in the acquisition of various tools and machines on the one hand and on the other to promote their products. These materials — is a convenient data sources for Amateur designers.
Advantages of adhesive bonding are well known. So to advertise no need. Amateur masters have long been actively using the method of bonding parts in their designs.
Currently, the range of materials has expanded considerably, and each requires its own glue. Need, unfortunately, is not always on sale. But in hardware stores and in the pharmacies you can buy individual components from which it is easy to make adhesives for many materials.
Today’s edition of the “Club house masters” introduces readers to recipes for adhesives that can be manufactured at home.
Wall
This popular English proverb builders could specify in relation to the construction of the building: its strength depends on three main components: Foundation, walls and roof.
Today we will focus on the constructions of external walls. Comments on Finnish Builder Pentti Jormanainen.
On the recommendation of the manufacturer to eliminate the memory effect of Nickel-cadmium batteries (NiCd) should clear their element to 0.4 V. For the implementation of the above requirements and automate the process of disconnecting the battery reaches level 0.4 V the authors propose a simple device.
To reduce the disconnection threshold of the discharge transistor /T2 is selected with a high rate of current transfer. The load (in addition to the resistor R2) and at the same time an indicator is incandescent НL with a voltage of 1 V at a current of 75 mA. In the absence of a low-voltage light bulbs a consumer may be led АЛ307Б.
For long distance carrying buckets with cement mortar, wire, shackle mercilessly cuts the hand, even if it is in the working glove. Of course, you can wrap the handle of any thickening. But that’s such a fast option — it is enough to use a wrench, as shown in the figure.
