One way of joining metal parts is soldering. With proper selection of flux and solder these connections are more reliable and can withstand a high load. Brazing is carried out various gas burners, with a supercharger and no bliss using as fuel liquefied propane. Homemade injector burner can be powered by cylinders with liquefied propane with a capacity of 1 litre (and cylinders must be equipped with a valve with a hose or cylinders with a capacity of 25 liters.
In the practice of homebrew somehow less common device is a bending machine. I don’t think this is due to the rarity can be accomplished with it operations, rather — the lack of information about how to do it. For example, I haven’t seen in magazines or technical literature his descriptions. But this simple tool is very useful: it allows even unskilled wizard efficiently curving blanks from sheet material. This ensures the absence of deformation at the bent portion of the sheet, making it impossible to achieve using the traditional mallet and mandrel. Experienced in the production of our NII bending machine proved to be indispensable in the manufacture of chassis of radio equipment, various housings, casings and connection sheets in the fold.
I am sure that many Amateur automakers in the manufacture of machines are faced with the problem of glazing of the body. Most of them come of the situation, “tied” to the size and shape of automotive glass, used in used on production models. I dare to undertake the furnishing of “jeep” glass type laminated glass cut at the required dimensions independently. This used the diamond cutter. On both sides of the triplex drew them risks which rattled up to the appearance of a crack along the entire length. Then remove the part warmed by the flame of a spirit lamp. Connecting the layers of the laminated film was reheated, which allowed us to pull pieces of glass to. tion between the gap. Then I have to cut the film with a sharp knife, and the uneven glass edges to be dulled with sandpaper.
Engraving machine is designed for deep drawing of inscriptions and drawings on metal or plastic. In the machine used flexible shaft with collet BorderStyle from the medical drill. The drive from the electric motor KD-30 UCH power of 60 watts (electric typewriter). The rotation of the motor shaft at a speed of 2700 rpm allows you to do without a reducer.
When soldering tin-lead solder emits vapours, which are very harmful, especially lead. The smell of rosin is not all pleasant. Some hams even have to leave your favorite passion – grumble’s household. However, there is a way to make exhaust ventilation. For example, I use this for over 20 years. When making use of almost everything is ready. The hoses and the top cover is taken from a vacuum cleaner. The snail and the impeller from the heater of the car “KAMAZ”.
Most comfortable furniture, “serious” joinery collect connecting parts on the thorns. Technical requirements for the quality of such nodes is usually very high. Run them by milling or using special equipment. Existing designs handmade kiparisov, regardless of their complexity, there are drawbacks, and one of them — a large thick spikes with little their length and the insufficient depth of the eyes, the inconvenience of zapilivanie, and hence risk of injury.
