Rare design can be build without the use of welding, particularly electric arc. This is why a good welder is a dream for many designers and enthusiasts. The “heart” of it — the welding transformer, which will be discussed. Winding step-down transformer (Fig. 1), connected to the original circuit (Fig. 2) provide arc stability. For welding use electrode Ø 3 mm, designed for AC current. (In the forced mode of the transformer it is possible to use electrodes with Ø 4 mm.)POLISH BANK…
I want to give advice to those who will plaster the walls of the clay-sand mortar. To produce a smoother surface you can use glass containers, for example, the 3 — liter jar. When the wall dries out a bit, need to iron it in vertical and horizontal direction, thus the Bank rotate optional. Internal Read more…
At that time, when decided to build a snowmobile, any particularly original design decisions and was not planned — the car was needed as a winter vehicle. However when picked up the necessary components, materials and set to work, began to appear the idea of different constructive solutions of some nodes. Even had some time to suspend work on the construction of the snowmobile and “to consider” the entire structure again — on paper. In the end, some decisions were not only unconventional (maybe not new, but considerably forgotten and not found in modern machines), and some original. Note design features.
To facilitate and accelerate mounting of mounted units and structures it is proposed to use a modified fastener — some modified gostowski the bolt and nut. The modification applies to their threaded parts on which are four symmetrical groove equal to the width of the remaining protruding threaded segments. Such design dramatically reduces the traditional time in the operation of screwing and defines a new technological approach to the works of this kind that is important in case of unfavorable working conditions or low temperatures.
Many tourists appreciated stankovye backpacks. They have a lightweight but durable rigid frame which provides a soft, in fact, haversack convenient box-like shape, more advantageous for laying the stowed cargo and carrying it on his back. But what about those who already have a backpack? Suggest to equip it with a built-in collapsible a frame of duralumin pipes. It will handle the load no worse frame easel purchase of a backpack. Besides, unlike the latter, can usefully stand for you in camp three of the four tubes are easily removed from the backpack and being connected together into, for example, in a solid rack. I have it, in particular, serves as the sole support of a makeshift tent tent.
