Today (2020-05-28) aviation history is once again being made, with the first flight test of an eCaravan, an electrified Cessna 208B Grand Caravan in Moses Lake, Washington. This will take place at 0800 PDT (Pacific Daylight Time)/ 1100 EDT (Eastern Daylight Time)/ 1500 GMT (Greenwich Mean Time)/ 1700 CEST. (Central European Summer Time). It powered by a 560 kW magni500 all-electric propulsion system.

MagniX is working with AeroTEC on this project.

This weblog post will be updated after the event.

World Goth Day: A tidbit

Ophilia (1851) by John Everett Millais (1829 – 1896).

Today (2020-05-22) is Goth Day #12. World Goth Day originated in at BBC in 2009, when Radio 6 was looking at a number of music subcultures including Goth music. Goth DJs Cruel Britannia and Martin Oldgoth decided that May 22 would be the day each year to celebrate it.

Unfortunately, being an active Goth has a number of negative consequences. Researchers Robert Young, Helen Sweeting and Patrick West write: “identification as belonging to the Goth subculture [at some point in their lives] was the best predictor of self harm and attempted suicide [among young teens]”, and that it was most possibly due to a selection mechanism (persons that wanted to harm themselves later identified as goths, thus raising the percentage of those persons who identify as goths).”

Thus, the decision to publish this weblog post has less to do with the celebration of World Goth Day in 2020, and more to do with helping susceptible people cope with life in this challenging period of time when we all face the COVID-19 pandemic. Let us reach out with friendship and inclusion (virtually or in real-life) to those who no longer feel part of society, including those who self-identify as Goths.

In order to talk with a Goth, it might be useful to know something about Gothism!

Of course there is an official World Goth Day website complete with a list of world events. I appreciate that one of the three goths decorating this page is following COVID-19 procedures, and is equipped with a face mask.

Many attribute the start of Gothism to English author Horace Walpole (1717 – 1797) who started it off by writing The Castle of Otranto (1764). Other readers may prefer to read Ann Radcliffe’s (1764 – 1823), The Mysteries of Udolpho (1794). Washington Irving (1783 – 1859) also contributed to the genre with The Legend of Sleepy Hollow (1820), also available in its Disney animated adaption, The Adventures of Ichabod and Mr. Toad (1949). Then again there are classics such as Bram Stoker’s (1847 -1912) Dracula (1897), and Anne Rice’s (1941 – ) The Vampire Chronicles (1976).

The first mention of Gothic Rock is by music critic John Stickney to describe a meeting in a wine-cellar with Jim Morrison, described as “the perfect room to honor the Gothic rock of the Doors“. While some musicians may favour The Velvet Underground as the ultimate Gothic rock group, my own preference is for Siouxsie [Sioux aka Susan Janet Ballion (1957 – )] and the Banshees, and their track Spellbound (1981). In Norway, the Stavanger band, Theatre of Tragedy, contributed to the Gothic metal genre with its beauty and the beast aesthetic that combined harsh male with clean female vocals. Other Goth oriented bands include: Bauhaus, The Chameleons, The Cure and Sisters of Mercy.

In terms of film, the 2019 South Korean black comedy thriller, Parasite, is outstanding, and should appeal to many Goths. Another film with Gothic elements is The Rocky Horror Picture Show (1975). Because of its black humour and general lack of seriousness, it may offer a suitable dose of escapism to help people struggling to cope with a pandemic. Other relevant films in chronological order include: The Hunger (1983), Beetlejuice (1988), The Nightmare Before Christmas (1993), The Crow (1994) and The Craft (1996).

There are also computer/ console based Goth games. The Gothic role-playing game series was developed by Piranha Bytes GmbH, in Essen, Germany. It consists of three versions Gothic (2001), Gothic II (2002) and Gothic 3 (2006). There is also a fourth version, Arcania: Gothic 4 (2007), developed by Spellbound Entertainment AG, from Offenburg, Germany. This company has reorganized as Black Forest Games GmbH.

Fashionistas are undoubtedly irritated about the late reference to clothing in this weblog post. Cintra Wilson (1967 – ), writing You Just Can’t Kill It, in the New York Times 2008-09-17, notes: “The goth subculture, however, for those who live it, is more than the sum of its chicken bones, vampire clichés and existential pants. It remains a visual shortcut through which young persons of a certain damp emotional climate can broadcast to the other members of their tribe who they are. Goth is a look that simultaneously expresses and cures its own sense of alienation.”

My own approach to the Gothic was not through literature, music, film, games or fashion, but art, especially that found in the works of the Pre-Raphaelite Brotherhood. Ophelia (1851) by John Everett Millais (1829 – 1896) is one such inspiring work. In addition, John Ruskin (1819 – 1900) was particularly attracted to the Gothic in architecture, which he commented at length upon in, The Seven Lamps of Architecture (1849).

Oatly & Einride: A tidbit

Oatly has devised a process to provide a vegan alternative to milk. Now it is concentrating on making that process more sustainable, but reducing CO2 emissions. Artwork: Oatly.

My personal transition from omnivore to vegan/ vegetarian is proceeding almost as slowly as my transition away from driving a diesel to an electric vehicle. One positive change, is that we purchase our eggs and milk (and some honey as well as produce) from neighbouring farms, rather than grocery stores.

I asked my personal shopper to add some Oatly products onto her shopping list. Instead, she invited me to help her shop at the local Co-operative in Straumen. Thus, I was able to purchase one litre (about a quart) of havredrikk kalsium (oatmilk calcium). Unfortunately, I was unable to find the other products I wanted to try: havregurt vanilje (oatgurt vanilla); havregurt turkisk (oatgurt Turkish) and iMat fraiche (Oat creme fraiche).

Oatly is a Swedish vegan food brand, producing dairy alternatives from oats. Based on research at Lund University. The company’s enzyme technology turns oats into a nutritional liquid food suitable for the human digestive system. The company operates in southern Sweden with its headquarters in Malmö, with a production & development centre in Landskrona. The brand is available in more than 20 Asian and European countries, Australia, Canada and USA.

Oatly claims to be a sustainable food manufacturer. Artwork: Oatly

Oatly also tries to be sustainable, by reducing its contributions to global warming. They also produce a sustainability report. It shows that almost half of Oatly’s contribution to greenhouse gasses comes from the cultivation of ingredients, a quarter from transport, 15% from packaging and 6% from production (p. 26).

Oatly is not perfect. For example, there has been some controversy about it selling oat residue to a pig farm. On the other hand, it has benefited from two publicity attacks. First, Arla, the Swedish dairy company, attempted to discourage people from buying vegan alternatives to cow’s milk (mjölk in Swedish) using a fake brand Pjölk. Oatly responded by trademarking several fictitious brands Pjölk, Brölk, Sölk and Trölk and began using them on their packaging. Second, the Swedish dairy lobby LRF Mjölk, won a lawsuit against Oatly for using the phrase “Milk, but made for humans” for £ (sic) 100 000. When Oatly published the lawsuit text, it lead to a 45% increase in Oatly’s Swedish sales. Once again, this seems to suggest that there is no such thing as bad publicity.

On 2020-05-14, Oatly and Einride announced that Oatly will use four 42-tonne vehicles starting 2020-10 to transport goods from production sites in southern Sweden, using Einride’s Freight Mobility Platform. This is estimated to lower its climate footprint (on the affected routes) by 87% compared to diesel trucks: 107.5 tonnes of carbon dioxide per year per truck, about 430 tonnes per year in total, or 2 100 tonnes throughout the five year duration of the contract.

Part of the solution involves optimizing electric trucks operations using computer-controlled logistics with Einride’s Freight Mobility Platform software. Accurate transport planning allows 24 tonnes of goods to be transported an average of 120 kilometers without charging. It involves optimizing and coordinating drivers, vehicles, routes as well as charging. On a typical shift, three drivers will drive four different trucks. This means that one truck is always charging, which places less strain on batteries, and making the operation more durable and economical.

This initial iteration involves a DAF glider (a vehicle without a drivetrain/ prime mover/ power source, fitted with a Emoss motor. Future iterations may involve a Einride Pod, previously referred to as a T-pod.

Shanzhai

The literal meaning of Shanzhai is mountain stronghold, referring to the bastion of a regional warlord/ bandit. Its remoteness protects it from centralized, official control. However, shanzhai also refers to an attitude, documented by Byung-Chul Han (1957 – ), a South Korean-born Swiss/ German metalurgist/ philosopher/ cultural theorist. He wrote Shanzhai: Dekonstruktion auf Chinesisch in German, published by Merve, Berlin in 2011. An English translation, Shanzhai: Deconstruction in Chinese appeared in 2017, published by MIT.

The chapters in the book refer to Chinese terms and their definitions. They are Quan: Law, Zhen ji: Original, Xian zhan: Seals of Leisure, Fuzhi: Copy, and Shanzhai: Fake.

As indicated by the name of the last chapter, shanzhai typically refers to something that is copycat/ fake. Another English word associated with it is tinkering. Before: A shanzhai factory has traditionally referred to a poorly equipped, low-quality, family-based production facility making inferior products. Now: Fewer of the facilities and products are of poor quality, despite no or fake brand labels.

Han realizes that it can be difficult for people of European ancestry to set themselves into a Taoistic mindset. “… transformation takes place not as a series of events or eruptions, but discreetly, imperceptibly, and continually. Any kind of creation that occurred at one absolute unique point would be inconceivable. Discontinuity is a characteristic of time based on events. (p. 8)

Han quotes Zhu Xi (1130 – 1200), who offers insight into shanzhai, and incidentally some pertinent advice for these COVID-19 times, “Under normal conditions we adhere to the rules of convention, but in times of change we use quan.” (p. 10) A quan is a movable weight on a balance scale. The implication is that there can be no absolute values, only relative values that have to be moved to find the point of balance.

There are some who equate Shanzhai with piracy, inside as well as outside China. At about the same time Byung-Chul Han was writing his book, Ni Ping (1959 – ), a Chinese actress and television hostess, proposed the elimination of shanzhai works, arguing that their copycat nature stifled genuine creativity and blurred property rights. During the ensuing debate, it was pointed out that shanzhai products are not pirated products. Genuine creativity is not so much originality, as it is government sanctioned creativity, which may be considerably less original than manifestations described as copycat. At one level, shanzhai is rebellion/ resistance to the mainstream.

Discussing Zhen ji, Han writes, “The Chinese idea of the original is determined not by a unique act of creation, but by unending process, not by definitive identity but by constant change.” (p. 13) This contrasts with Plato’s concepts of the beautiful or good, which are immutable. Being is replaced with a multiform, multilayered process. Masterpieces will be deconstructed/ viewed differently in different ages. He notes, “Copying is the same as praising.” (p. 16)

Han then examines Orson Welles’ (1915 – 1985) docudrama, F is for Fake (1973). “Elmyr [de Hory (1906 – 1976)] is deliberately painting badly so that his forgery looks more like an original. In this way he turns the conventional relationship between master and forger on its head: the forger paints better than the master.” (p. 17) Han then goes on to remind readers that Michelangelo was a forger of genius, substituting perfect copies for borrowed originals. (p. 19)

Han regards seal stamps (xian zhan) as part of a picture’s composition. Indeed, space is left on paintings for later inscriptions. These seals vary in size from 4mm to 200 mm in diameter, and may include poetic or moral content. They open up a communicative space, vastly different from the signature affixed European artworks. (p. 21 – 22)

In the chapter Fuzhi: Copy, Han reflects on terra-cotta warrior copies. While the Hamburg Museum für Völkerkunde regarded them as forgeries in 2007, the Chinese replica workshop regarded its efforts as an attempt to restart production. (p. 31) Han further notes that the Japanese Ise Shinto shrine temple complex is completely rebuilt from scratch every twenty years, despite being 1 300 years old.

Modular production from stock components is regarded as appropriate behaviour, for in Chinese society originality/ uniqueness is not as valued as reproducibility, allowing variations and modulations. (p. 35) Han then refers people to one of the most famous Chinese treatises on painting the Manual of the Mustard Seed Garden (1679).

In the last chapter, Shanzhai: Fake, Han writes, “There are now also expressions such as shanzhaism, shanzhai culture, and shanzhai spirit. Today shanzhai encompasses all areas of life in China. There are shanzhai books, a shanzhai Nobel Prize, shanzhai movies, shanzhai politicians, and shanzhai stars.” (p. 37)

He then goes on to discuss where the term was first applied, cell phones. “In terms of design and function they are hardly inferior to the original. Technological or aesthetic modifications give them their own identity. They are multifunctional and stylish. Shanzhai products are characterized in particular by a high degree of flexibility. For example, they can adapt very quickly to particular needs and situations, which is not possible for products made by large companies because of their long production cycles.” (p. 37)

Shanzhai by example

Billi Sodd 2015 Anstendighet/ Modesty 1910

Billi Sodd is a persona representing an older prisoner with issues, yet in the process of developing himself to become a(n artistic) painter. Since he is learning, he refers to himself as an apprentice, rather than a journeyman or a master. Like everyone, he was imprisoned by his past, until he decided to break free of it. Yet freedom is a relative term. At the most fundamental level, no living human is free to stop breathing. Every person is a slave to biological imperatives.

Billi’s most significant work so far, Anstendighet/ Modesty, consisted of 8 paintings. These paintings are based on a single template, a stencil. They deliberately imitate cartoons with large patches of solid colour, and an absence of shadows. Anstendighet/ Modesty was made in 2015, and shows how the western concept of modesty has transformed itself during during a period of 100 years. It consists of six paintings showing a young (ca. 20 years old) adult women at twenty-year, generational intervals from 1910 to 2010, each dressed in bathing costumes of the time. In addition, there are two additional paintings, variations on this theme, showing potentially more extreme changes for 2030, labelled 2030 Mini and 2030 Maxi.

The so-called originals were given to Verdal prison. However, a reworking of the subject is planned, with the goal of releasing high-definition images, so that anyone could make their own giclée prints using ink-jet printers. As long as the printing instructions are followed, these prints would be regarded as equals to the original paintings. If the instructions aren’t followed, something even better than the original may result.

In many ways Billi is an antithesis to protesters in these COVID-19 times, who want to open society faster, pressing R0 (in this case the viral net reproduction rate) values to greater heights. It is disheartening to see people like Elon Musk complaining about the shutdown of Tesla’s Fremont factory. He seems to have forgotten the lesson learned from a childhood reading of Isaac Asimov’s Foundation series, reported by Neil Strauss, “you should try to take the set of actions that are likely to prolong civilization, minimize the probability of a dark age and reduce the length of a dark age if there is one”.

An invitation to the original showing of Billi Sodd’s work Anstendighet/ Modesty (in Norwegian and English) in 2015 can be downloaded using the download button below. VF refers to Verdal fengsel = Verdal prison.

In 2020, Billi is considering a new series, PPE, based on current experiences of COVID-19. No decision has been made regarding the number of paintings. It could be as few as two. One showing protective measures taken during the 1918 Spanish flu epidemic, as well as the current one. A third, simply showing a child hiding under a school desk, and titled nuclear attack, could refer to events in the early 1960s.

After this re-emergence, Billi Sodd next appearance is expected to be a celebration of Billi’s permanent release from Verdal prison at a Halloween party to be given on Tuesday, 2028-10-31. The theme of this party will be shanzhai. Mark that date on your calendar now!

Here are three additional relevant quotations from Han’s book.

“In the Buddhist notion of the endless cycle of life, instead of creation there is decreation. Not creation but iteration, not revolution but recurrence, not archetypes but modules determine the Chinese technology of production…. Foremost in modular production is not the idea of originality or uniqueness, but reproducibility. Its aim is not the manufacture of a unique, original object but mass production that nevertheless allows variations and modulations.” (p. 35)

Shanzhai products often have their own charm. Their creativity, which cannot be denied, is determined not by the discontinuity and suddenness of a new creation that completely breaks with the old, but by the playful enjoyment in modifying, varying, combining and transforming the old.” (p. 40)

“The creativity inherent in shanzhai will elude the West if the West sees it only as deception, plagiarism and the infringement of intellectual property.” (p. 41)

Closing thoughts: People’s transformational abilities, that is, a competence to alter/ convert/ reconstitute raw components into something useful, are to be applauded. Take the steam engineer, who is able to extract latent energy found in assorted solids, liquids and gasses and mould it, so that it works for the benefit of humankind: moving train cars, drying lumber, generating electricity. Take the weaver, who is able to take flax (from Linum usitatissimum) or fleece (from Ovis aries) and transform it into cloth. Take the programmer who, using a simple vocabulary, instructs a computer to manipulate data to provide and display meaningful information.

Allen, Lin Zuzao, Cheng Xiaolan and Jan Bos.

Yang Jianxin writes that “According to the historical records, wood blocks for printing started in the Tang Dynasty (618–907 A.D.). During that time in the center of Zhejaing Province, a book store sold the collected poems of Bai Juyi and Yuan Zhen in an edition printed by wood blocks.” (Allen et al, p. 26)


Open Source Ventilator Project

The University of Florida Health Open Source Ventilator (Photo: University of Florida)

The Center for Safety, Simulation and Advanced Learning Technologies at the University of Florida Health has developed open-source, open architecture ventilator engineering design specifications to address a predicted ventilator shortage worldwide due to the COVID-19 pandemic. It will also host open source contributions.

The above link directs people to a website that provides sufficient information to construct such a ventilator, although attention is also focused on the disclaimer at the bottom of the page.

Other news sources have also provided more readable information on the project.

It is claimed that hardware for the project is readily available at hardware stores. Parts were purchased at Home Depot. There are claims that the ventilator can be produced with $300 in parts, in addition to labour. I note that the controller is an Arduino based unit. The Arduino is a very simple controller board, that I have used in my teaching from 2008 – 2016.

If you (or someone you know) would like to work on this or similar health projects, please contact me at: brock@mclellan.no

MIT Emergency Ventilator Project

E-Vent, a team of volunteers, scientists, physicians and computer scientists at MIT revived a 10-year-old ventilator project. The result is an affordable and easily replicable, but primitive, ventilator design. The total parts cost is $400 to $500, . The E-Vent team plans to share their design online on their website so that manufacturers and companies can recreate the lifesaving device for hospitals around the world.

The device’s main part already exists in most American hospital inventories: an Ambu resuscitation bag. Usually, these are manually operated by emergency technicians or medical professionals to keep a patient breathing until they are hooked up to a ventilator. The E-Vent team adapted the Ambu bags by attaching it to an automated mechanism that replicates a human. This project appears to be more expensive, and less functional than the University of Florida project.

Construction: 2020 Season

The building/ construction season is starting at Cliff Cottage today, 2020-04-01. Today, equipment will be positioned. Tomorrow, 2020-04-02, if all goes well, the utility trailer will be taken out to purchase building supplies, so that these do not become a bottleneck. This date is chosen because it is the first day after we come out of quarantine.

This building activity means there will be less time to write weblog posts. Unless something changes, posts will be published only on the first day of each month, from April (this post) to September 2020.

The weblog season will begin again 2020-10-01, with a post that has already been written, titled Hipster. Other posts about computing equipment have also been written.

COVID-19

COVID-19 is the name of a coronovirus disease first identified 2019-12-31, of an animal to human zoonotic event that occurred at the Huanan Seafood Wholesale Market in China. According to Wikipedia, zoonosis is an infectious disease caused by bacteria, viruses, or parasites that spread from non-human animals (usually vertebrates) to humans.

This event did not affect me personally for 56 days, until my arrival at AMS, Amsterdam Airport Schiphol, on 2020-02-25 at 9:00. It was then that I was asked if I had visited China, or had any of the known symptoms. While our flight OSL – AMS did not include anyone wearing face masks, there were at least four passengers on our AMS – SFO flight.

Since then, events have intensified.

On 2020-03-17, NRK, the Norwegian Broadcasting Corporation, was reporting that Norwegian (the airline) was refusing to transport non-Norwegian-citizen residents back to Norway. One day later, two members of my family and I did not have this problem with Delta/ KLM. Everything went smoothly. We had gone to Detroit after San Francisco. At DTW, Brock had to present his residency card in order to get a boarding card to fly from AMS to TRD. Trish and Alasdair had no problems with their Irish passports.

On arrival at TRD, a representative of the authorities boarded the plane, and read out the rules. This included 1) no tourists would be allowed to land, but would be transported back to AMS, 2) that passengers must remain quarantined for 14 days, and 3) that people with corona symptoms would not be allowed on public transport, but would have to use private vehicles. After that Norwegian citizens were allowed off the plane. Once they were off, the rest of the passengers were allowed off. That could have been about 8 people, including us. We then had to present our passports at the immigration desk. They checked our status, and allowed us in. Then we had to be inspected by the health authorities dressed in hazmat outfits. Again, we were allowed to proceed. We picked up our luggage, and ran to the train, arriving on the train platform with a minute to spare.

Alasdair used his Vy (the train company) app to buy the train tickets. There were very few people on board the train. Alasdair had to “inspect” the tickets for the conductor who, before Corona, would normally be handed the telephone and press the ticket inspection button him/her-self. We then contacted our personal food shoppers by SMS. Trish had days earlier sent them a shopping list, and now paid them using our “Vipps” (bank) app.

At Røra station, we found our car – almost without any snow on it. We then drove about 7 km to Straumen, where we picked up our groceries, from the back of the shoppers’ vehicle, and transferred them into the back of our vehicle. We talked to the shoppers who had come to the door of their house, thanking them, but keeping a distance of at least three meters. Then we drove 13 km home to Cliff Cottage.

As this is being written, there are now 6 people dead from Corona virus in Norway. The average age is 89! Our local area has opened a special emergency clinic for people with respiratory problems.

The Norwegian krone has never been so cheap (or the American dollar so expensive). Today, it was 10.50 to the dollar.

On our arrival home, we began our 14 day quarantine. Because we are symptom free, we can walk in the woods and work outside, but have to avoid people.

Covid-19 World Cup/ Superbowl

The Covid-19 World Cup/ Superbowl will be taking place on 2021-01-01. This will allow cities/ counties/ states/ countries/ regions/ continents in the world to compare themselves with all the other players. There will be winners and losers in all categories. At the very least, everyone will be comparing themselves against China.

As Oliver Milman reported: The US is on course to be severely ravaged by the coronavirus outbreak due to a delayed and dysfunctional testing regime and misleading messaging from the Trump administration, public health experts have warned. (2020-03-15 02:54) Unfortunately, this early tactic of denial will probably put USA towards the bottom of developed countries.

Milman also cited an editorial by Herbert Holden Thorp (1964 – ), a chemist, inventor and entrepreneur as well as the editor-in-chief of Science:

For the past 4 years, President Trump’s budgets have made deep cuts to science, including cuts to funding for the Centers for Disease Control and Prevention and the NIH. With this administration’s disregard for science of the Environmental Protection Agency and the National Oceanic and Atmospheric Administration, and the stalled naming of a director for the Office of Science and Technology Policy – all to support political goals – the nation has had nearly 4 years of harming and ignoring science.

Now, the president suddenly needs science. But the centuries spent elucidating fundamental principles that govern the natural world—evolution, gravity, quantum mechanics—involved laying the groundwork for knowing what we can and cannot do. The ways that scientists accumulate and analyze evidence, apply inductive reasoning, and subject findings to scrutiny by peers have been proven over the years to give rise to robust knowledge. These processes are being applied to the COVID-19 crisis through international collaboration at breakneck, unprecedented speed; Science published two new papers earlier this month on SARS-CoV-2, and more are on the way. But the same concepts that are used to describe nature are used to create new tools. So, asking for a vaccine and distorting the science at the same time are shockingly dissonant. (End quote)

The fantastic thing about this championship is that there are any number of metrics that can be used to describe winners in contrasts to losers. Of course, politicians are not really interested in this at all. They have a vested interest in explaining why their area is fantastic, and other areas are not. Even then, not all countries/ states will be playing fairly. Some metrics can be found today. The first metric is population, along with an estimate of the percentage of people aged over 60/ 65/ 70, if this is available. Another metric available immediately, is the number of intensive care unit (ICU) beds. Figures from 2012, show this to be 8.0 per 100 000 people in Norway. More recent figures show figures for the world in the following graph.

The dates of test kit availability, and their first testing indicates how prepared the country/ state was. Indeed, the legitimacy of other metrics are, in part, dependent on the availability of these kits. At the end of the year, it will be important to know: how many people were tested; the number of positive test results, which with sufficient numbers of tests, could be an indication of the breadth of infection; the number of associated deaths. In order to compare players, data must be expressed as a percentage, or more usefully, absolute numbers per 100 000 people.

South Korea will undoubtedly emerge as the winner of the world cup/ superbowl, teaching the world how to approach similar epidemics. Given its population of 50 million, 74 new cases emerged on 2020-03-17 in contrast to 909 at its peak on 2020-02-29. Later, Reuters reported that South Korea kept new infections around a low 100 or less each day.

Numbers may yet resurge. Behind Korea’s success so far has been the most expansive and well-organized testing program in the world. This has been combined with extensive efforts to isolate infected people and trace and quarantine their contacts. South Korea has tested more than 270 000 people, (5 200 tests per million inhabitants). In contrast, USA has tested 74 per million inhabitants, according to the CDC.

“Diagnostic capacity at scale is key to epidemic control,” says Raina MacIntyre, Professor of Global Biosecurity at the University of New South Wales, Sydney. “Contact tracing is also very influential in epidemic control, as is case isolation.”

Legislation enacted in South Korea in 2015 gave the government authority to collect mobile phone, credit card, and other data from those who test positive to reconstruct their recent whereabouts. That information, stripped of personal identifiers, is shared on social media apps that allow others to determine whether they may have crossed paths with an infected person. In addition, South Korea established 43 drive-through testing stations, and in the first week of 2020-03 their Ministry of the Interior rolled out a smartphone app that can track quarantined people and collect data on symptoms.

In contrast to South Korea, and even China, USA is the developed country that I expect to come in last place. This will demonstrate that private insurance (and health care) have no place in the modern world. It may indeed indicate an end of USA’s (and capitalisms) dominance in the world, especially with respect to the economy, and innovation. In the short term, I expect a brain drain of intelligent people, and others with the opportunity to leave, from USA for places with better health care, and welfare. Canada, New Zealand and Europe will be sought after destinations. Australia and Asia, not so much. In Europe, and Italy especially, Cuba and Russia have received praise for their aid and assistance during this crisis. Perhaps these two countries will also be sought after destinations for disillusioned Americans.

In Scandinavia, there will be a regional competition between three groups of countries: Finland, Sweden and Norway/ Denmark. Finland looks as if it will be the winner.

Bjørgulv K. Bjåen writing behind a paywall in the Norwegian newspaper Vårt Land, states that Finland is in a special position. While other Nordic countries have reduced their emergency preparedness stores, the Finns have chosen to have large emergency stocks – buffers – especially with respect to drugs. In the current situation, it looks like the Finnish government will stop sales and exports of these from Finland.

Because of its Second World War experiences, Finland became a borderland between the East (The Soviet Union/ today’s Russia) and the West (Western Europe/ today’s European Union). For a decade after 1945, it had to pay major war reparations to the Soviet Union. In the process they learned to make things that they had never made before, such as icebreakers.

The contingency idea has massive support in Finland. After 1991, the Soviet Union was disbanded and four decades of a hot Cold War cooled. Sweden and Norway downsized emergency stocks, in contrast to Finland’s continued crisis thinking that embedded the principle of being prepared for surprise.

The Finnish Medicines Agency (Fimea) currently has a list of 1 400 drug types that are stored in so-called turnover stocks: One should at all times have enough for six to ten months of consumption. Manufacturers, wholesalers and hospitals rotate stock, as a matter of principle. Normal consumption is calculated from last year’s consumption.

Norway has chosen another solution. Until the EEA regulations became Norwegian law, Norway had large emergency storage facilities organized by the state medical Norwegian Medical Depot (NMD). However, after the EEA Agreement entered into force in 1994, the wholesale company changed its character; from state, to semi-state, to privatized. The Norwegian parliament (Storting) decided that the state monopoly had to be disbanded because it was in breach of EEA law. No one had told Norway to disband it.

This has resulted in the down sizing of emergency stocks, and the have been scaled down, and responsibility has spread to many players. In a report from last year, National Drug Preparedness, the Directorate of Health acknowledges major shortcomings:

“Many actors with different responsibilities for drug preparedness in Norway make the landscape unclear.”

“Only a marginal proportion of medicines consumed in Norway are produced in Norway.”

“Contingency stocks in Norway are largely concentrated in the central Eastland area, and also have inadequate content”.

“The specialist health care procurement systems are not robust in terms of drug preparedness.”

“Many municipalities have not secured emergency supplies of medicines for the health services they provide.”

“There is low awareness among the population about the importance of having a supply of necessary medicines at home.”

Sweden also recognizes that emergency storage has been replaced by the idea that most can buy something when it is needed. Last year, the Swedish Defence Research Institute analysed Sweden’s supply readiness. Finland copied Sweden’s earlier model for total defence planning and developed it further, while Sweden reduced it. There is now a shortage of drug readiness stocks.

In Sweden, emergency preparedness changed dramatically after it joined the EU in 1995.

Finland also has large emergency stocks with other important crisis products, fuels, groceries, seed, grain, metal and agricultural spare parts. Fuel stores are to secure up to five months of consumption. Grain stocks will last for six months.

In Norway, emergency grain storage facilities were closed in 2003. Today, grain storage is sufficient for only three weeks. In 2014, the Norwegian Institute for Agricultural Economics Research presented a report that said grain stocks were low.

When the right-leaning Solberg government presented the state budget for 2020, it was stated by the political parties supporting the government, that national emergency stocks for grain are not needed, because Norway can buy grain from abroad. That the supply lines are completely blocked off “for some time will not be seen as realistic”, Minister of Agriculture and Food Olaug Bollestad reported in the budget document.

Marcus Carlsson, a mathematician at Lund University, discusses two approaches to pandemics in a video, mitigation and suppression. The upper model in the video shows mitigation. This is the strategy Donald Trump appears to favour 2020-03-25, and the one implemented in Sweden. It is the same one used by South Korea, but with one major difference. To be successful, it requires extensive testing and tracking of cases, from the beginning. Until now, USA has lacked the ability to test. Yet, Trump is afraid the economy might tank without this approach. Others believe that mitigation might cost an extra million, or more, lives in USA, and take at least two years to complete. Not only that, the economy will probably still tank.

Carlsson is not an epidemiologist. He is an amateur. However, he is concerned that there is no evidence of a “herd immunity” approach controlling a virus outbreak anywhere in the world, without extensive testing. He described the Swedish government’s approach as “a mad experiment with 10 million people”.

A second approach, the lower model in Carlsson’s video, is suppression. This is the approach being used in Norway and Denmark, and in most other European countries, including two that have recently given up on the first approach – Britain and the Netherlands. According to Carlsson, this is the preferred approach, especially if there is a lack of testing. In the video he reads from a paper supporting it.

In an article in the Guardian newspaper, that describes Carlson, and comments on the 18m mark of the video, Carlson calls Sweden’s chief epidemiologist, Anders Tegnell, deceptive.

The Directorate of Health (Hdir) and the Norwegian Institute of Public Health (FHI) recommended different strategies to the government. They chose to follow Hdir and suppression, rather than FHI and mitigation. If suppression fails, then mitigation will be used.

Interestingly, Hdir has been given an overview of how much contamination equipment, including personal protective equipment (PPE), is available, but it is secret. They believe the figures will create fear, uncertainty and weaken Norway’s position in the international market if it becomes public knowledge.

FHI’s fourth risk assessment for covid-19 was published 2020-03-24. This assessment is translated into English immediately below.

In the risk assessment, FHI presents the first estimates of the number of infected in Norway with projections of the number of infected, the need for hospitalization and intensive care for the next three weeks.

  • FHI recommends that the choice of strategy for the further course is postponed one to three weeks. During this period, among other things, a better basis for decision can be obtained, in particular knowledge of the effect of the measures from March 12, says Director of Public Health Institute Camilla Stoltenberg.

In the coming weeks, it is crucial to win time and fight the epidemic with measures that can significantly reduce the spread.

  • A clear goal for the strategy is important. A key premise is that there is only high enough population immunity that can provide lasting protection against new, large outbreaks – this is achieved by getting many people infected or by vaccine, says Stoltenberg.
  • The choice of strategy and measures is made under great uncertainty, and there is a need to obtain more and better knowledge quickly and continuously, she continues.
    Prerequisites for the risk assessment

The Institute of Public Health is working to understand the situation and provide forecasts for the epidemic’s development in Norway. For this, a mathematical simulation is used together with real-world data, especially on hospital admissions.

The Institute today presents the first estimates of the number of infected persons in Norway with projections of the number of infected persons, the need for hospitalization and intensive care for the next three weeks. Thus we also have the first estimates for the dark figures in Norway.

There are still major uncertainties, and forecasts may change next week. As the epidemic progresses, FHI will have better data that can be built into the model, and the institute will adjust the model. The assumptions used in this assessment are:

  • Overall mortality among infected persons below 1% (lethality).
  • Severe age-related mortality; 90% of deaths in the group > 70 years.
  • About 1% of all infected people will need hospitalization and ¼ of these will need mechanical breathing assistance.
  • The measures should be adapted so that you get RE (the number of infections, ie how many an infected person is infected) down towards and maybe below 1.
  • Depending on the strategy choice and the effect of measures, we can expect that around 5% – 50% of the population will be infected during the epidemic.

FHI’s recommended strategy

It is clear that measures to reduce the number of infections are necessary. The choice of strategy and measures is difficult and must be done under great uncertainty. There are no simple solutions, and all strategies are experiments. Decisions with potentially major ripple effects must be made under uncertainty, regardless of who takes them.

FHI recommends that the choice of strategy for the future course be postponed one to three weeks. During this period, a better basis for decision can be obtained, in particular knowledge of the effect of the measures from 12 March.

Furthermore, the institute will develop new tools to optimize testing, isolation, infection detection and quarantine. This work is in full swing and moving forward at high speed. During such a period, the burden of measures can also be analyzed, ie the negative effects of the measures on societies, businesses, groups of sick and individuals, including consequences for life and health, and build better capacity in the health service. (End of Assessment)

In Norway, we get a daily status report from FHI. A summary of this status report for 2020-03-25 follows.

A total of 2,916 infected persons have been reported. This represents 54.3 cases per 100 000 in population. Of these, 264 of the infected were reported in the last 24 hours. 00:00 to 24:00. Highlights from the day:

  • 12 deaths have been notified to the Norwegian Institute of Public Health (2020-03-24 at 08.00). The average age of the dead is 84 years.
  • The average age of those infected is 47.7 years, 46.8 percent are women and 53.2 percent are men.
  • 1 437 people have been infected in Norway. 1 043 have been infected abroad and for 350 the infection site is being clarified. Of those infected in Norway, 724 have been close contacts of a known infected case and 671 have no known path of infection, 42 are being clarified.
  • In Norway, 73 089 have been reported tested for coronavirus (SARS-CoV2) (as of 2020-03-25 at 12.00).
  • 237 patients admitted to hospitals with proven covid-19 (figures from the Directorate of Health as of 2020-03-25 at 12.15). The number of admissions per day is increasing.
  • There are a total of 74 persons who have been or are in intensive care with certified SARS-CoV-2, of which 51 are hospitalized (figures from the Norwegian Intensive Care Register). The average age of those admitted to intensive care is 60 years. Of these, 77% are men. (End of status report)

Politico asked 34 opinion makers how they expected COVID-19 to change the world. They comments are interesting and warrant attention. Unfortunately, Politico did not reach out to anyone at Cliff Cottage. Brock’s expectation is that this epidemic, will lead to increased ruralization. That is, the urbanization trend will be stopped, and there will be a new back to the land movement, reminiscent of the early 1970s. Activities where random people congregate will decline. These will include visits to stores, bars, cafes and restaurants, theatres and cinemas, amusement parks, casinos and sports stadiums. The concert era has ended. The cruise ship era has ended. Instead, people will focus on small-scale growing of their own crops, and entertain themselves at home, producing their own music and art.

Tim Lang, is concerned about food supply, and fragile supply chains. For several years now, I have been talking (but not doing anything practical) about the use of 15 m2 (150 square foot) geodesic domes as hydroponic greenhouses to grow foodstuffs. People without gardens can grow food on balconies. People without balconies can grow food indoors. I did buy some LED lights optimized for plant growth. However, everyone should be considering how they can grow their own supply of food.

For several years now, I have suggested purchasing an abandoned motel and setting it up as a commune. There would be a common kitchen, dining hall, and socialization area. Half of the units would be used for accommodation, half as workshops.

In terms of location, I have often wondered about – then dismissed – Ocean Falls, British Columbia. This has had an important place in my wife Patricia’s family history. Her uncle, Mort Heaps, was mill manager. Her sister, Aileen, was a nurse at the hospital. This video provides an overview of its current state.

Other locations that I have considered are located in the southern interior of British Columbia, or Vancouver Island/ Gulf Islands/ San Juan Islands/ the rain shadow of the Olympic Peninsula.

This scourge will end! For every activity that is eliminated, a new one will emerge or more likely re-emerge. There could be changes. Online shopping will predominate, while physical stores will decline. Some shopping centres may be re-purposed, but many will have to be bulldozed. Hopefully, their area (including parking lots) can be used for other purposes, including housing, recreation and urban agriculture. People will grow and process more of their own food. Hopefully, it will be healthier and more organic.

Printers

Conclusion: A printer is no longer the necessity it once was. Frequency of use is part of the equation in determining what type of printer (if any) to buy. Often alternative sources can provide all of the printing resources needed. At other times, it may be prudent to invest in a colour laser printer with scanner.

Before rushing out to buy a printer there are several questions that should be asked, and answered.

  1. Who in the household needs to use a printer?
  2. What do each of these people want to use the printer for?
  3. What will their monthly production/ consumption be of premium colour print, regular colour prints and black and white prints?
  4. How much will each person need to scan objects?
  5. What alternative printing and scanning sources are available? at what price?

Unlike most of the products discussed until now, the answers to the above questions will show that most families will probably not need their own printer!

Ink in an ink jet printer will dry out, if not used at least once a week. Thus, most people with low usage requirements and an alternative printing source, will find that owning a printer is an unnecessary expense. While ink tanks attempt to make printing cheaper, they are only a solution if one is printing a large number of sheets regularly. Ink jet printers have a problem with drying out, regardless of how the ink is provided. Using an ink jet printer at home – say, once a month – will be frustrating and potentially expensive, as one has to cope with, and repurchase, dried out ink cartridges.

Laser printer toner cassettes do not dry out. They can be used minimally without problems. This is one reason why the author of this weblog post has purchased a laser printer, and disposed of the previous ink-jet printer. The laser printer is used mostly at the end of the month to make a paper copy of accounting documents, ingrained from long-forgotten accounting courses, that required people to keep a paper trail of transactions. Other people may not feel this need. Laser printers are more expensive to purchase than ink jet printers.

While many product reviewers are keen to emphasize the existence of monochrome (read: black & white) printers, these may be offering false economy. An inability to print a document in colour, may make the entire printing process irrelevant. A colour printer, can always print in black & white. Standard printing size is 8.5 inches by 11 inches in North America, and A4 in Europe. There is no need for most households to deviate from this. If there is, time should be spent sourcing where appropriate printers can be found, and used.

There are essentially three types of printing: Premium colour printing on glossy paper, for photographs and renditions of artwork, regular colour printing and black & white printing.

There are many brands of printers available. In my working life I have been subjected to too many HP printers that have had a number of technical issues, such as jambing. In my personal life, Epson has provided the most toxic experience, with its incessant requests to change ink cartridges to those that are Epson branded. In Norway, vendor lock in of this sort is illegal. I have used unofficial inks with Canon ink jet printers without problem. Currently, we are on our first set of original toner cassettes on our Canon i-sensyn MF633cdw printer, so this situation has not been tested, although unoriginal replacements have been purchased.

Many printers are classed as multi-function machines, a misnomer, as they usually add just a scanner. However, this ability to scan documents may tip the scale towards printer ownership. Once a document is scanned, it can be sent as an email attachment. Some printers can even offer faxing as an option. In the circles I frequent, faxes are cult items in the same category as telex machines. Both are irrelevant technologies. However, this is not the situation in all parts of the world, where faxes are still used.

A household printer should be connected to the household computer network of handheld devices, laptops, desktops and other computers. Normally, there is absolutely no need to have more than one printer in a house. There are several ways you can go about installing a network printer. However, two are most common. It can be part of the Wi-Fi network using an infrastructure controlled by your router, or it can be wired using Ethernet. Many printers are also able to read memory sticks, using a USB Type-A port. Not many printers are equipped with USB-C, yet.

There are several alternatives to owning a printer/ scanner. If one attends school or works for a living, there may be formal or informal arrangements for printing/ scanning documents. Some may require payment, others may not. A public library may provide an inexpensive service for patrons. Some office supply stores may also provide this service, charging for each page printed. Then there is FWB, a friend with benefits, which in some contexts may refer to something completely different, but here refers to a friend willing to let you use her/ his printer/ scanner. This may be precisely the benefit you need from a friend.

Another approach is that you become that FWB, and offer a printing service to people you know. This is not a money making proposition, but could be a way of reducing costs provided you are prepared to charge people for the services you provide. Collecting money is easy with an apps developed for this purpose: Venmo provides smart phone apps for payments in the US, Fooi does the same in Canada, and there is Vipps in Norway. Note: There may be more appropriate payment services that I am unaware of. If so, please let me know.

Scheppach HF-50 Spindle Moulder

The Scheppach HF-50 Spindel Moulder/ Router Table. Photo: Scheppach

In North America, a table saw is often used to cut dados (square sectioned grooves). A stacked dado blade set is a sandwich of blades to be fitted onto a table saw for making dados and rabbets. There are two rim (outer) blades. These differ from each other and are referred to as the left rim and the right rim blade, respectively. There is also a series of chippers, specially-designed blades that fit between the rim blades, as well as dado shims aka spacers, that lack any cutting features, but vary in thickness. They can be made of metal or plastic. These ensure that the dado is the precise width that is needed.

The arbour (the axis or shaft that supports and rotates the blades of a table saw) has to be long enough to accommodate the stacked dado blade set. This is the challenge with European table saws. Their arbours are too short to accommodate more than a single blade, and still allow the nut to be fully threaded onto the arbour when the blade is tightened. Thus, making dados is a task that is normally done with some form of router in Europe. The main problem with this approach is that there are is not an unlimited choice of router bits to select from.

While most routers are portable machines, something approaching a table saw is also available, but with a rotating vertical shaft, rather than a horizontal shaft. The spindle moulder (British English)/ wood shaper (American English)/ router table (General) comes with a motor, frequently housed below the table surface.

The Scheppach HF-50 is a machine for DIY enthusiasts, rather than professionals. The author’s many different Scheppach tools, were all purchased for work on a house renovation project, and are not intended to be kept beyond its completion. These are not especially durable machines. The main reason the HF-50 was purchased, was the lack of choice. Professional machines cost five times more than the NOK 3 300 (USD 300) spent, and at least twice as much used. The HF-50, and many other machines, will be replaced by the end of 2023 with a CNC machine, probably with a router as well as laser cutter. It may even include a plasma cutter. Such a machine costs about 20 times the price of a router table, but will provide greater production flexibility.

In contrast to a router, stock (the unprocessed wood) runs along a vertical fence from right to left. Viewed from in front of the infeed, the cutter head can be described as a right-hand vertical side head. Other configurations include a bottom horizontal head, a left-hand vertical side head, and a top horizontal head. A single head moulder will only cut one surface at a time. It is common for multi-head moulders to have up to four heads.

The spindle is height adjustable from 0 to 40 mm. While most spindle moulders rotate between 3 000 and 10 000 rpm, the HF-50’s speed varies from 11 500 to 24 000 rpm, close to that found on a portable router. The cutters shanks have a diameter of 6 mm / 8 mm / or 12 mm. Power on the HF-50 comes from a 1 500 W motor. Other spindle moulders may have as little as 750 W, to as much as 5 000 W per head.

Hearing, eye and respiratory protection are necessary when using a spindle moulder. The machine itself is usually equipped with a guard above the cutter, to protect hands and prevent garments from being drawn into its blades. Hold-downs and feather-boards can also prevent injury.

There are two major jobs intended for the spindle moulder. The first is to use it to make drawers for kitchen cabinets. This will follow some of the advice of John Heisz in his video, How to Make Drawers the Easy Way, with additional information provided by Gary Katts in the video, The Quarter-Quarter-Quarter Drawer System. Quarter inch is translated as 6 mm.

The second is to make moulding that for LED strip lighting, that will be covered with translucent plexiglas. This is a relatively simple design, that will allow much of the house lighting to be DC powered. Electricity will be supplied using Power over Ethernet (PoE) standards. PoE cables are in place throughout the house.

In addition, I intend to make an oak table from counter-tops. Since the width of the table is 900 mm, while a counter-top is 600 mm, this means two edges will have to be planed, using a spindle moulder, rather than a jointer. This eliminates one more tools from the workshop, saving space.

After these three projects are completed there will undoubtedly be other projects that will use the capabilities of a spindle moulder.

External Drives

In this weblog post several different types of external drives will be examined for different purposes.

Hard Drives

The main purpose for having external drives is to have off-site backup of files stored on a family Network Attached Storage server(NAS). It is to ensure that irreplaceable data is not lost by storing it in two separate locations. There are five drives with historic data that are permanently kept at a second location. This is because all that data is already on the NAS. Then there are six drives that are divided into two sets of three disks each. One set is taken regularly to the second location. Once there, the other set is returned home, and used to update files on a regular basis for the next couple of weeks. In a worst case situation, a catastrophic event would result in the loss of up to two weeks data.

Currently, hard drives offer lower price than solid-state drives when mass storage is needed, particularly in the range of 1 – 5 TB. Western Digital My Passport products are inexpensive, but offer good performance. This is due to using the USB 3.0 protocol, with its cable terminating in a Type-A connector. In addition it comes with an excellent disk controller. There is 256-bit AES Hardware Encryption available. The maximum transfer read speed is 174 MB/s , and the maximum write speed is 168 MB/s. In general it offers acceptable performance and reliability.

If one selects the Western Digital My Passport Ultra, there are two main differences. First, it uses a more robust metal enclosure. Second, the USB 3.1 protocol is used, with its cable terminates with a USB-C connector, but includes a Type-A adapter.

There are different manufacturers of HDD units including Samsung, Seagate and Toshiba. I have mainly kept to Western Digital, because none of my eleven My Passport drives have failed. In contrast, one of my two Seagate Backup Plus drives failed after minimal use. The second, remaining Seagate drive was quickly given away. Others are not so enthusiastic for My Passport drives. Slant ranks two versions of Seagate Backup Plus as the best drives. I have also considered purchasing Toshiba Canvio drives because of their compact physical size, but their smaller 3TB capacity makes them less practical for a person with large quantities of data to store.

Solid-State Drives

Solid-state drives (SSD) become expensive with large capacity disks. The Western Digital My Passport SSD is considerably more expensive, with storage capacity ranging from 256 GB – 2 TB. There is a USB 3.1 Type-C port and AES 256-bit hardware encryption. At the moment, the main disadvantage of these drives is price, which is more than four times the HDD equivalent.

Transfer speed is up to 540 MB/s. This speed increase is because SSDs access data electronically instead of electro-mechanically. This also improves their mechanical ruggedness. There is continued debate about the reliability of SSDs, with some finding them more, others less, reliable than HDDs. SSDs are sensitive to sudden power interruption, which can result in the loss of a drive.

While there are wireless drives, not all devices are equipped with Wi-Fi. Almost without exception, these devices are equipped with USB ports. Thus, there is no need to invest in wireless external drives.

USB flash drives aka memory sticks aka thumb drives

Flash drives are used for various purposes. Perhaps the most common use is for the transport of files when a person will not accompanied by their own laptop or other machine where the files are normally used. They are especially useful if one has to upgrade a number of machines to several different devices.

For these purposes one wants a fairly rugged and durable piece of equipment. Personally, I use a Kingston DataTraveler Elite G2 64GB flash drive. For the security minded, the main drawback of this drive is that it is not encrypted. If necessary, one could password protect sensitive individual files. One reason for selecting this drive is its metal casing, which is shock- and water-resistant. It reads at a maximum of 180 MB/s, and writes up to 70 MB/s.

The more security minded may want to consider a SanDisk Extreme Pro USB 3.1 available in 128 and 256 GB varieties. Its read and write speeds are extreme, up to 420MB/s and 380MB/s, respectively. It has an aluminum casing and comes with 128-bit AES encryption software. Its price is also extreme.

One of the main uses of flash drives here, is the storage of assorted Linux operating system distros. Each distro is placed on a new Kingston DataTraveler G4 16 GB flash drive. At one time, these were upgraded as new distro versions became available. However, after a couple of drive failures one learned that this was false economy. 16 GB drives are used not because one needs so much space, but because they are cheaper than 8 GB drives!

There are many times one needs to give people files on a flash drive. This has to be regarded as one of the normal costs of having relationships with people, in much the same way that serving visitors (invited or not) a cup of coffee is an investment in smooth social relationships. These G4 drives are the standard drives given to people. They are usually bought online, ten at a time.

SD Cards

While this section is labeled SD cards, some would argue that microSD cards would be a more appropriate heading. The original SD format is far too large for handheld devices. If a port on a device only takes original or mini-sized cards, passive adapters are available.

Whetstone Sharpener: A tidbit

A Scheppach TiGer 2000 Whetstone Sharpener. Photo: Scheppach.

At my local hardware store (Jula), there are electric grinding stones in all price categories from NOK 250 to 3 200 (USD 32.50 to 416). I paid NOK 1 500 (USD 195) for mine. Why this price difference?

Depending on your worldview, the Rolls-Royce, Maybach, Cadillac, Zil, Toyota Century or Trek (yes, the bicycle) of the grindstone world is Tormek, a Swedish manufacturer. If you want to be convinced that one should spend more money on a whetstone sharpener, there is a YouTube video that explains everything, Why does the Tormek T-7 and T-4 cost so much? Interview and review with Stig from Sweden: https://www.youtube.com/watch?v=ESW3wy0PI18

Not being convinced, I opted for a Scheppach TiGer 2000 S, which looks like a plagiarized version of the Tormek T4. The T4 is undoubtedly better. One person suggests 20% better, whatever that means. It also comes with a 7 year guarantee.

While larger diameter grindstones are preferred to this 200 mm machine, because they provide a larger concave grind on edge tools, these larger machines also need a more powerful motor and housing, making them more expensive.

While the unit comes with both a straight jig and an angle guide, some users may want to invest in a wheel dressing jig to flatten/ true the stone edge. Specialist jigs are available for knives, woodturning tools, axes and scissors.

Mount the stone wheel and plugging it in, is all that is needed to set up the machine. The metal shaft is strong. However, the sharpening jig fits loosely. Many reviewers have commented that a Tormek jig is much better. The 120 W motor is more than adequate. Most tools can be ground adequately. The leather honing wheel is also adequate.

Note: The first three paragraphs of this tidbit were originally written: 2018-03-18 at 07:15:29 with the title Workshop Tools: Whetstone Sharpener. Since then it has been waiting for further inspiration, that has never arrived. On 2020-03-08 at 23:00 the text was edited into blocks using the new(ish) Gutenberg block editor, rather than the Classic editor used in 2018. The title was changed to Whetstone Sharpener: A tidbit. The last three paragraphs were added, along with an illustration of the Scheppach TiGer 2000. Prices in NOK were identical in 2018-03 and 2020-03. However, the Tormek had increased its price to NOK 3 800. In 2020, 1 USD is worth almost 10 NOK, this will also influence price comparisons.
