Jigsaw is perhaps the most popular tool in the home workshop craftsmen, and in the laboratory modeller. Meanwhile, its design has remained unchanged for decades, but this does not mean that it is perfect.
Gardeners will appreciate the trolley-sledge, shown in the figure, because it can be used all year round. Necessary, for example, in summer, carry some cargo, put it on the cart, put on wheels and roll her along the earthen path, grass, asphalt. But winter comes the turn of runners: turn the cart, and she was again ready to work.
Like it or get a hose clamp or wire the ends of pneumology, no one can guarantee the strength of the connection: the internal air pressure will do the trick. And if force this pressure to use to secure the hoses to each other? This idea I have embodied in a specific construction of the clutch. It is based on the building, reminiscent of a car tire (made, of course, of metal). In the case of slotted radial grooves into which is inserted four levers. Inside the case is another “car tire” — this time from elastic rubber.
The washing machine is firmly established in our everyday life. And if in cities, the connection of washing machines to the water supply will not cause a problem, in rural areas, where there is no Central water supply, and take water from springs and wells to run such a job much more difficult. And it is caused primarily by lack of water-supply system or insufficient pressure in it. Generally, washing machines are designed to work with the pressure of the incoming water 0,5 — 10 bar, which can only pressurizing pump either based on Autonomous water station (the latter is possible to buy it now at the price of 5000 rubles).
Fluorescent energy-saving lamps in recent years become increasingly popular, despite its relatively high cost. Indeed, all the good these lights are, but the one absurdity of spoiling their reputation. Adapted standard electroputere E27 bulb (photo 1) are too large (diameter) of the Central contact area and when screwing them into the cartridge cases when the site closes both contact.
In the mid 50-ies of the last century, the magazines wrote that the burned out light bulb is a real treasure for lovers to make all their own hands. In particular, it was reported how to do from her flask retort magnifying glass and other very useful things. Nowadays a genuine treasure for homebrew are … used disposable medical syringes. It is no secret that they are already being applied by the craftsmen as greasers, neat coils, easy to install circuit boards. Sure, a decent place can take these syringes and in the Arsenal of computer geeks when filling cartridges inkjet printers, which (I speak from experience) are difficult at home. It is most difficult when filling is black (by the way, the most common) color.
It is known that the standard diameter of a pencil stylus and the inner diameter of the collet gripping for him, the compass does not correspond to each other: terminal to insert, we have to undermine. Even more hassle, if you want a colored pen. Yes, and to rescue the rest of the pencil is also not a simple matter: it will only be with a needle or knife.
All probably know what a kicksled. Very comfortable design, but it was too heavy and bulky. Once the IIA came up with the idea: is it possible to lighten them and make them leaner? It turned out. For this it is necessary to leave only one snake. As the audit showed, these sledges it is possible to ride even a Threesome.
The magazine has repeatedly printed design microvesicles on the basis of details of children’s bikes and motors D-5 and D-6, however mainly for use in the summer. We with the friend decided to create a machine where you could go in summer and winter.
