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.

“RAZLAGALSA” BATTERY

18.05.201813.05.2018Devices helpers

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.

THE HANDLE OF THE WRENCH

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.

ARTIFICIAL LIMBS

A mechanical device capable return man, some of the functionality lost in the loss of an arm or leg, called respectively an artificial arm or artificial leg. Artificial hands and legs together under the General title of artificial limbs ).
Artificial hand, as a rule, operate by reducing the preserved muscles, but sometimes for this purpose there are special electrical, hydraulic or pneumatic drive system. This artificial hand is classified as a so-called prosthesis with reinforcement.

“COPPERBAR” OF “GRINDER”

The device, which I have called “cappenberg”, I constructed at the time when he decided to make an improvised wheels for walking tractor. Wheels with a diameter of 320 mm were cut using this tool.
With a small hand held cutting machine (popularly referred to as “Bulgarian”) model GREAPO PG125SE, made her a simple, but reliable, and most importantly—the right fixture for cutting parts in the form of a circle of sheet metal or holes in it.

THE FOUNDATION OF THE HOUSE

Finnish design houses have established themselves as comfortable, warm and resistant to seasonal phenomena and time. About the peculiarities of laying the basements and foundations of such country houses Builder says Finnish Pentti Jormanainen.
Do you know how are called the parts house? If not, carefully review Fig. 1.
And what determines the strength of the structure? It is known that the load that can withstand bearing and protecting designs of the house are due to natural phenomena under the influence of its own weight structures and are associated with the operation of the building. The various types of loads and impacts experienced by the house, as shown in figure 2.

WATER COOLING THE CPU

In this article I will try to tell about my attempt to make a water cooling system for CPU in the home. This will describe the highlights and technical details on my own experience. If you are interested in a detailed illustrated manual for the manufacture, Assembly and installation of such a system, it is welcome under the cat.

ALUMINUM CANS

Buying another jar of soft drink, consider the following – aluminum cans always be recyclable. Unlike plastic, aluminum will not deteriorate, no matter how many times it is melted and used again. Aluminum cans, of course, very light. It must be hard to imagine that they are made from a huge roll of aluminum sheet and weighing 9 tons! The width of the sheet about half a metre and one roll is enough for the manufacture of 750,000 cans.

THE HUNT FOR HEAT

Drafts — no. In the preparation of housing for the winter the first step in city apartments is the sealing of Windows and doors. The simplest solution for Windows is pozatykat cracks and seal them with paper tape. Of course, this measure makes it impossible to open the window for the entire winter, but reduces heat loss.

Ventilation can also produce through the balcony door or specially left unburied part of the window (in the case of tricuspid of its design), as well as the window.
