Home Workshop

I have been subscribed to "Modeler-Constructor" for a long time and find a lot of useful things in it, especially in the "Club of Home Craftsmen" section. On the advice of the magazine, he made a lot of things for the house and garage.

But I don't just use other people's ideas. I design myself. For example, I have a home-made planer with interchangeable pieces of iron, which, it seems to me, could be useful to a home master. The tool is easy to manufacture, and it can perform several operations: planing, chamfering, taking quarters and, importantly, choosing grooves of different widths and at different distances from the edge of the part.

The block of the planer is made of hardwood. It has a notch, a thrust plate seat, a groove for the head of the locking screw, as well as front and rear steps with grooves for the bolts for fastening the limiter bar.

A plywood sidewall 5 mm thick is attached to the block with six screws. Its use drastically simplifies the manufacturing technology of the block - the notch can not be hollowed out with a chisel, but cut out with a hacksaw.

A piece of iron with a cutting edge designed for a particular operation is first connected with an M3 screw to the cubic head of the adjusting screw, then inserted into the entrance (for an additional M4 through screw passing through the block and sidewall) and fastened in the cutout of the thrust plate with a wing nut and a lock nut M4. The adjusting screw sets the thickness of the chip removed in one pass, or the depth of the groove (depending on the shape of the cutting edge).

Universal planer (click to enlarge): 1 - M4 wing nut (3 pcs.), 2 - M4 bolt (3 pcs.), 3 - sidewall fastening screw (6 pcs.), 4 - sidewall, 5 - block, 6 - fixing screw, 7 - adjusting screw, 8 - locknut, 9 - screws for fastening the thrust plate, 10 - thrust plate, 11 - piece of iron (A, B, C - cutting edge options), 12 - limiter bar, 13 - nut M4, 14 - screw M4.

The distance from the edge of the part at which it is necessary to select the groove is determined by the limiter bar: it is fixed with two M4 bolts with wing nuts. And not only the distance, but also the width of the groove, because thanks to the rearrangement of the bar, you can, working with the same piece of iron, get a groove of the required width.

I made the pieces of iron from the blade of a metal saw that has served its time (easel), but you can also make them from a strip of tool steel.

I am satisfied with my planer: the surface quality obtained when processing parts is quite satisfactory.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Speech slows down due to nouns 28.05.2018

After analyzing 9 languages, scientists came to the conclusion that speech slows down before nouns. The study was conducted by linguists at the University of Zurich.

A team of theoretical linguists led by Balthazar Bickel decided to conduct a study and find out which part of speech is more likely to slow down articulation - a noun or a verb.

The researchers recorded the speech of native speakers of 9 languages, among which are minor languages - Chintang, Even language, Winnebago, Ntsyu and others. Separate words (about 300) were highlighted on the records, which scientists divided into parts of speech. Further, linguists left only verbs and nouns and began to study pauses.

It turned out that all native speakers of the studied languages slowed down their speech due to pauses, which were more common before nouns. However, there was also a slowdown before the verb, but only in one of the languages taken for the study - English.

Scientists explained that people use nouns when they need to say something that was not discussed before. This contributes to pauses, which have recently noticeably slowed down live speech.
