Marking time on technology
Etymology of a microphone
As I was reading about the technicalities of sound recording, I wondered where the lavalier microphone got its name—(a lavalier is the little microphone you sometimes see clipped to peoples’ shirts when they are interviewed on TV). I did some digging and here’s what I found.
What’s in a ballet shoe
In Sheffield (once the great centre of cutlery manufacture) the person who assembles and adjusts scissors is called a putter-together, sometimes putter-togetherer, often shortened to putter. It takes years to develop the skill and judgment to do this job really well.
In this video we see Cliff Denton at work. He is a putter at Ernest Wright & Sons Ltd, one of the few Sheffield businesses that still makes high quality scissors in the traditional way.
I have been at the Woodford Folk Festival for a couple of days, giving a little presentation about researching environmental issues.
Instead of the usual bring-your-own-tent arrangement, I stayed in Tent City. This is an area where somebody else has already put up the tents before you arrive, and has put comfortable beds in them. There is also a communal tent with a cold room, tables, chairs, and boiling water on tap—and a table with mains power where campers can charge their phones. When I looked, the table was covered with a mess of Apple iPhones, and very few other types.
Moon signals at Bustard Head
I found this in the Queensland Figaro newspaper, 24 September 1903. The same story also ran in the Launceston Examiner, the Wagga Wagga Advertiser, the Melbourne Argus, the Hobart Mercury, the Zeehan & Dundas Herald, and the Rockhampton Morning Bulletin:
It was while locum tenens at the rectory of Gladstone, Queensland (says a writer in Chambers’ Journal for August) that I became aware that moon-signals could be used in the same way as those of the sun. It was my duty to go to Bustard Head Lighthouse every few months to hold service and visit the Sunday-school and people of the station. I usually went by land, and rode 30 miles to Turkey Station; and as soon as I arrived Miss Maud Worthington, the daughter of the station owner, would at once heliograph the news of my arrival at Bustard Head, and enquire by use of an 8 in looking glass at what time a horse could be sent to meet me on the other side of the swampy ground, over which it was wiser to walk. There I was met by Mr Rookesby and his wife, who piloted me to the lighthouse station. Mr Rookesby is a well-known inventor in Queensland. He erected the heliograph between Turkey Station and the lighthouse, but failed to make communication with Gladstone, 84 miles off, either because an 8 in mirror was too small, or because of other conditions peculiar to the lie of the country. He then experimented with signalling by moonlight, and discovered that—notwithstanding the feeble light of the moon as compared with sunlight—owing to the darkness of the night, the moon’s reflections were quite powerful enough to carry the intervening 10 miles between the two stations.
A severe blow
A while ago in Dunedin I visited the Otago Settlers Museum, an institution founded in 1898, the 50th anniversary of the first Scottish settlement of Otago. In the beginning the museum focused on the earliest European arrivals—from 1848 until 1861 when the gold rush started. The focus gradually widened to acknowledge more recent arrivals and, eventually, the Māori people who had been there all along. In 2012 the museum was renamed Toitū Otago Settlers Museum. Toitū is the Māori name of a stream that once flowed near the site, and the word carries other connotations, as the museum website explains.
In the museum is an ‘early colonists’ gallery, purpose-built in the early 1900s. In this large square room, lit by lantern windows at the top of the hipped ceiling, there are hundreds of framed photographs stacked six rows high. It’s very impressive, and gives the impression that anybody who can’t point to an ancestor on the wall is a newcomer.
Making rasps and rifflers
I have some cabinetmaker’s rasps in my kit, but they are the common machine-made kind. I have never used a hand-made rasp. Perhaps I should.
Rasps and rifflers are still made by hand in the old way by a few small manufacturers, like Forge de Saint Juery. The video below shows how much skilled handwork goes into making these tools, which explains why they are rather expensive. To justify the cost, it is claimed that hand stitched rasps work better and cut smoother than the machine made ones, as Chris Schwarz explains»more»
Some work I’m doing at Cape Moreton Lighthouse prompted me to do just one more search for historical photographs and drawings online. At the National Archives I found something new—this drawing, signed by W Wilkins, lighthouse engineer of Long Acre, London, of a proposal for Cape Moreton lighthouse, the first lighthouse in Queensland and the only one built of stone.»more»
Kodak in collapse
The news that Kodak has filed for bankruptcy in the US prompts me to think about this company, which dominated the commercial and technical aspects of photography throughout the twentieth century. Among the many Kodak products I have used, I fondly remember my first two cameras, the Carousel projector, Kodachrome film, the 100 mm Wide Field Ektar lens on my first 4x5 camera, and countless Austral postcards.
In 1888, with the introduction of the first Kodak camera George Eastman changed photography by allowing ordinary people to take photos without needing their own darkroom. The camera was sold loaded with a roll of film that could take 100 pictures. Owners sent the camera back to the Kodak factory for processing, printing and reloading. Hence Kodak’s slogan, “You press the button, we do the rest.”
This was a social transformation as great, in its time, as the introduction of the mobile phone camera.
I haven’t shot any Kodachrome for years, but I feel a slight sadness knowing that I’ll never be able to do so again. Kodak stopped selling the film a year ago, and the last Kodachrome lab in the world (Dwayne’s Photo Service, in Kansas) will stop processing the film in the next few days. This marks the end of a long run—since 1935—for a film that was noted for its sharpness, colour fidelity and archival stability.»more»
Gentle reader, if you know where this photograph was taken, please send me a message. The picture shows a small town gasworks, newly built or under construction. In front of the camera is the gas holder with five blokes sitting or standing on the empty vessel. Behind on the left is a shed (for storing feed stock?) and in the centre a brick building (the retort house?). No chimneys are visible (odd?). The style of the photographic print suggests a date in the 1870s, ’80s or ’90s. The name of the photographer suggests the place shown may be one of the 61 former gasworks sites in New South Wales. Any ideas?
Bill Blair, trug maker
I was in New Zealand last week studying Oamaru’s wonderful Victorian limestone buildings. Beside the harbour I found Bill Blair. In an old tin shed he makes wooden rakes, pitch forks, grain shovels, firewood carriers and other products of woodland hand craft. His best-selling item is the Sussex trug, a type of wooden basket which he makes in a range of sizes. I bought one as a gift for my long-suffering partner Margie, who I had left holding the fort while I enjoyed this solo sabbatical.»more»
On 24 August 1942 R A Cook, wheelwright and blacksmith of Goondiwindi, wrote a note on his printed invoice paper. I can’t be sure of the name of the recipient, but the note went like this:
Just a line to ask you if you can supply me with some river oak billets for bullock yokes. They want to be 4ft 11 long by 6 x 6. If you can, let me know what price for same. I require (15) Fifteen and I want them quick.

Researchers at Rochester Institute of Technology have been studying Georges Seurat’s A Sunday on La Grande Jatte—1884. Their research paper describes their work—here’s the abstract:
George Seurat first employed his divisionist painting technique on A Sunday on L Grande Jatte—1884 beginning in October 1885. Painting with pigments representing colors seen in the visible spectrum that were minimally mixed on the palette and using divided brushstrokes, he aimed to impart luminosity to the surface and to explore 19th century ideas of color theory, such as simultaneous contrast. Pigment analysis has disclosed that the brushwork containing zinc yellow has darkened significantly: Yellow, green-yellow, and orange brushstrokes have become brown, olive-green, and reddish brown, respectively. Additionally, the painting has further darkened due to the natural aging of the oil medium. By performing spectral reflectance measurements in-situ on darkened areas of the painting and on paint-outs of comparable unaltered colors, using Kubelka-Munk turbid media theory, imaging the painting with colormanaged digital photography, and image editing with Adobe Photoshop, a digital version of the original, more luminous appearance of La Grande Jatte was simulated.»more»

Discussion of the ingredients of cutler’s resin continued on the oldtools list today. Steven Longley has turned up an American supplier of pine resin, also called brewer’s pitch. You can buy it from Jas Townsend & Son, Inc.
Daniel E L Yurwit added this to the exchange:
FWIW, the Apache also made jugs woven from plant fiber (a “tuss”) to carry water, and coated them heavily with pine tar resin to waterproof them. Some still work effectively 100+ years later.»more»
Pardon me, as I jot down a recipe. Cutler’s resin is 8 oz pine pitch, 1/4 cup carnauba wax and 4 oz of beeswax, melted together in a double boiler and used hot. Mark Marsay wrote on the oldtools mailing list:»more»
The way we do business in the military
From a mailing list message from an American soldier in Afghanistan:
Technology has changed the way we do business in the military. It does seem somewhat bizarre to have unfettered internet access in the middle of nowhere. I can sit in my tent with my ThinkPad and email, IM, and browse the internet the same as if I was sitting in my living room back in Georgia. Myself and 39 other buddies purchased a satellite system from an outfit out of India. The ISP is actually in Germany and we get just about T1 bandwidth which is split up 40 ways if everyone is on (which doesn’t occur due to different work shifts). We “beam” it out via Wi-Fi to the different tents. Even our aircraft (I’m in a CH-47 Chinook unit) are on an intranet of sorts. The system called Blue Force Tracker allows secure tracking of all the different aircraft (and ground elements) within the theater real time. We can email between aircraft and to our headquarters during flight…all with satellite technology. I’ve hardly sent a snail mail letter since I’ve been here.

More online exhibitions: The Science Museum puts neat little exhiblets on its website. Like Blockmaking, eight pages about machines from the Royal Navy block factory, set up in 1805. The factory pioneered mechanised production of large numbers of identical widgets. Lots of blocks (which sailors never call pulleys) were needed on sailing ships — the exhiblet tells us that a seventy-four gun ship needs 922 of them. So the ship’s block was a good candidate for factory production.»more»

The Morse Telegraph Club is a group of enthusiasts interested in any topic concerned with Morse code and telegraphy. Probably the biggest constituency in the club is retired landline Morse operators. Each year, the various chapters around the country meet on Professor Morse’s birthday to remember the good old days of landline telegraphy and the heyday of the railroads. In addition, keys and sounders are dusted off and telegraph circuits are established with other chapters around the country. Morse code is soon heard clicking from sounders and greetings are received from friends in other chapters.
