My user name “aclassifier” (or “Aclassifier”) is a pun that originates from my experience with collecting and describing (“classifying”) my first-generation short-and-tall Mercedes-Benz A-Class scale models. The result of this attempt is still to be seen here. Then, A-Class’ifiers became aclassifier. I have used that name whenever there was a need for one. Nowhere has this information been classified!
This blog is all about all my attempts with that broken saw (it’s always starting out as difficult, the saw is not cooperating!) and then how I, after having tried long enough show what I’ve come up with. I am not starting up as an expert on anything, so I try to also show the paths I walk.
I have some header images that are chosen randomly by WordPress:
This header image is from the inside of Torre del’Orologio (Torre del Candeliere or Torre dell Orologio) in Massa Marittima in Italy. The picture is not edited in any way, but the clockwork is indeed inside a glass box. It is the basis for one of the stories in my short story book Og der sto, du (in Norwegian).
This header is a close-up of a bouquet of flowers. Believe me, the gerbera flowers are orange, and the flower vase has the form of a cone all the way down. (The vase is by ceramist Asbjørn Pettersen. I bought it in Mandal, Norway).
This header’s idea is to show the graduated scale of the world’s first “voltmeter”, as seen at the The Volta Temple in Como in Italy. It is a “straw condenser electrometer in square bottle” or electroscope (as earlier built by Cavallo and Bennet) – but this time with a graduated scale, so it’s the first electrometer (displayed as item “305” at the museum; it’s an original from Volta’s hands). The pendula (arrow) are two straws, as the title suggests.
I found this mechanical counter at a second-hand shop here in Trondheim, shown here without its hood. On this odd architecture (for my purpose) of five non-connected three digit counters I had to press 1025 times to display those 8 digits. With a specialised arrangement with three counters and 2+2+4 digits I would have needed only 26 presses. But this arrangement of iron plus added colour would never feel days go by. No matter how much fancy iron we added.
I visited Verkerhs Museum Dresden (Dresden Transport Museum) in August 2018 and discovered this electric motor of 2400 kW. The E52 42 loco from 1926 is no more, but this is claimed to be the world’s most powerful electric motor for locomotives. I used a long time to feel it, enjoy it, be overwhelmed by it. In some way it reminds me of what my father Hans-Jacob Teig did as his first job in 1935-1945: winding the stiff copper cables of hydro electric generators. He was proud of this work and had some tiny 6×6 cm pictures of it. I have it in my blood. This stuff moves me. See the full motor (without the frame and the wheels) here.
I discovered this double sided anchored chain, visible through the ice the day before, and the following day brought my camera. I probably would thought about using my mobile if I knew the motive would have been gone by the next day. But I reckoned even the transparent ice would survive. I couldn’t forget it since it was hard avoid thinking about the strong symbolic power of this motive. Press picture for the high resolution version (or should I say “normal resolution”. 960×250 for the headers is not very much..). It’s shot by Dokkhuset at Solsiden here in Trondheim on 16Dec2018. Aside: I wasn’t 100% satisfied with the Panasonic Lumix DMC-LX5 picture presented here. So I brought a newer DMC-LX100 the day after, and even shot in raw format. The picture was technically better, but something had happened with the ice and light. The ice was perhaps more melted and rounded on the edges of the broken-off pieces. And one could barely see the chain below the ice. So I really could not replace the technically best with the dramatically best.
These “decoder wires” (as intended to be used inside model trains) each consists of 26 copper strands of diameter ⌀ 0.05 mm. That yields π * (0,05 mm / 2)2 * 26 ≈ 0.05 mm2 area of copper to carry lots of electrons around. Each cable can then deliver about 0.5 Ampere without getting hot. The isolation is PVC, neeeded just like the myelin sheth covering our nerves. Fully assembled each cable has ⌀ 0.6 mm. The picture is taken in 2019, when I discovered these wires. However, the rather complex technology behind a cable like this is quite old – even if my father and colleagues used cotton and oil around the much thicker wires when they made power generators at NEBB in Oslo in the late 1930’ies. Lately I have had to dissect multi-wired cables to find wires half as nice as those pictured. I bought some cardboard (more or less suited), and made the pictured future proofed multi-reel unit.
