How to firmly and securely fix a wooden workpiece during its processing? There are such wedge vise applicable for both small parts and long boards.

The device can be made at home. A groove is hollowed out on the right side of the board. To its edges, flush with the upper edge, the guide strips are firmly screwed. Between them, two wedges are inserted into the groove. A metal visor with teeth is embedded in one, with which it must dig into the end face of the workpiece. Another wedge acts as a lock. It firmly holds the wedge with the visor in a fixed position, the wedges, as well as the guide bars, must be made of solid wood, namely beech, oak.

Wedge instead of vise

The part is fixed and released from the clamp with light blows of a hammer sliding along special cutouts made for this on the wedges.

The second stop for the workpiece is a pin with an iron comb. It is inserted into one of the nests hollowed out in the board.

In order to be able to fasten parts of different lengths, the distance between adjacent nests should not exceed the length of the groove.

When processing thin parts on a workbench, the protruding parts of the wedges and checks should not rise above the plane by more than 10 mm. Otherwise, it is difficult to rigidly fix the workpiece.

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

Renoir 7nm Desktop APUs - Ryzen 4000G, PRO 4000G and Athlon PRO 3000G 22.07.2020

AMD has unveiled the Ryzen 4000G APUs for the AM4 desktop platform, sister to the well-established 7nm Ryzen 4000-series mobile chips. They are intended for the OEM segment and will not be available in retail stores, but in the future AMD promises to release some models of new APUs for the DIY market (with boards based on AMD 400 and 500 series chipsets).

The Renoir desktop APUs use the same 7nm die as their mobile cousins, with eight Zen 2 physical cores, 8MB of L3 cache, and eight Compute Units (CU) graphics on the improved Vega architecture. But if mobile Renoirs run into a 35-watt TDP, then desktop counterparts raise the bar to 65 watts, operate at higher frequencies and, therefore, their performance level is higher.

Renoir desktop APUs officially support DDR4-3200 RAM (while AMD used faster DDR4-3600 memory in performance tests), the x86-core frequency reaches 4,4 GHz in the case of the flagship Ryzen 7 4700G model, and the integrated GPU runs at 1700- 2100 MHz depending on the model.

Also introduced are the Ryzen Pro 4000 and Athlon Pro 3000 APUs for business-class ready-made computers. They are related to consumer models (the characteristics are completely identical), but at the same time they have advanced support and security technologies (full encryption of RAM and AMD Pro feature set).
