I worked as a mechanic gardening vehicles, or simply petrol lawn mowers. Often had to cut the grass and shrubs in inconvenient places, and in restricted areas. And the existing braids and large manual shears are ill-suited for such work. So I decided to ease your work — to come up with a portable hand tool for cutting bushes, flower beds and lawns. Asked domestic and foreign experience of construction of such mechanisms, sketched some sketches mowers with various actuators, including electric. However, before the reali- organization of ideas was far away: we were not satisfied with a single node, then the other.
If the plane piece of iron are induced to razor sharpness, and the Board you plane them, without knots n ROE, from the plane pours a silky ribbon chips such strength and beauty that sweep it into the trash just a sin.
Arch, gate, gate, fence, walkway, typically all these elements construct a new HOMESTEAD or garden plots are not in the first place: imported materials, construction details, tools, seedlings, processed a site built structure is hassle enough, and the fence at first, just a hindrance. But come to her hands; there are the traditional questions:
High-quality sound speakers for home sound equipment to reproduce low-frequency signals with a frequency of 30-50 Hz, which corresponds to the length of the sound waves 7-10 m. in Order to efficiently radiate such fluctuations, we need a dynamic head with a large diameter of the diffuser (there are instances d of 400 mm). However, in practice most commonly used “dynamics” with the size from 200 to 300 mm. Their own resonant frequency in the range of 15-30 Hz.
to Make a bunk bed I was forced circumstances. A small area of the apartment is not allowed to make beds for the children, so I decided to make a double-Decker. I worked on the ships of the merchant Navy and for the sample decided to take the ship’s bed, but with the ability to manufacture at home from available materials. Sizes are determined taking into account the fact that children grow quickly and the time will come when the bed will be small. Therefore, the calculation was done for an adult of average height.
In a wooden house, the attic is always somehow seems low, dark and cluttered room. And if a little dream and to imagine him as he is shown in our drawings? Look, another one, and maybe two comfortable living rooms will be at your country house or dacha, it is only the room under the roof to turn the attic — cozy and bright.
The proposed transformable workbench can be used not only at home but also in workshops, at stations of young technicians; “fit” it in the garage.
The scroll saw is a common tool. However, when working with him, guys sometimes faced with certain difficulties: the blade breaks, POPs out of the clips, if the cut on a curved path is often twisted, making it difficult to maintain the required direction.
Probably unlikely pharmacist Leeuwenhoek invented the microscope, not whether it is a variety of lenses. In our time, for those who want to make a microscope, may be more difficult: telephoto lenses, increasing only two-three times in the pharmacy enough, but short-much harder to find. But most are not.
