Home Workshop

We offer you a simplified method for manufacturing a cylindrical gear rack. You can make it using a conventional tap, choosing the profile of its thread in accordance with the gear you have.

Gear rack on a lathe

Before work, make the simplest mandrel - a steel bar with a hole where the tap is inserted. The tap itself should be finalized - grind it on emery by about half. Processing is carried out as follows. A workpiece is loaded into the machine - a cylindrical bar, the machine is turned on, and an impromptu cutter is brought to the rotating workpiece. The bar is cut to a full thread profile (in this case, it is necessary to remember the divisions of the vernier of the transverse feed), the cutter is retracted and the longitudinal feed handwheel moves to the left (along the cone!). The cutting operation is repeated.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Atomic takeover 04.09.2006

The sharp tip of a tunneling microscope's needle can pick up and move atoms - but only one atom at a time. In principle, this process makes it possible to assemble nanotechnical devices built from individual atoms, but the work is progressing very slowly.

Scientists from the French Center for the Development of New Materials, in collaboration with colleagues from the Free University in Berlin, have created a tip molecule for the tip of a tunneling microscope.

The molecule, which is based on a benzene ring of six carbon atoms, captures up to four atoms at once and allows them to move with an accuracy of 0,1 nanometers.
