a bridge and a tailgut

Pirate luthier adventures continued ...

The second violin I obtained via Freegle (number 9 in my logbook) came from outside Oxford and was very kindly delivered to my doorstep. It is a Chinese one from the 1960s and came with its original case and two hairless bows. It was lacking the bridge and the tailgut so I had to cut a new bridge, which is an enjoyable job to do. A lot of the filing and scraping is compatible with multitasking, so I watched the news and a movie while doing this. When the bridge was in a reasonable shape (I can always sand and scrape it a bit more at a later point but I was impatient), I set it up with a set of spare strings that came with the pair of SkyLark violins I bought recently. (There were only three strings in the case of this one and two of them were gut strings.) So now it looks quite lovely:

Building bridges is always a very satisfying job to do ...

I made the new tailgut from an old gut string that came with Heinrich the cello:

Note that the body is slightly thicker than the other violins I have. In fact the measures are identical to the 14" primavera viola I have, so I wondered whether this one was also meant to be a viola. I am told however, that it was only ever used as a violin (many years ago), so I also set it up as a violin. At first playing, it sounds surprisingly nice, even with a nondescript set of old strings. I am particularly impressed by the warm sound on the higher register - coming from the cello I have high expectations for the range where both instruments overlap, but don't expect to be wowed by the E string. Will share a video at some point. The attempt to record the same tune with all four violins for comparison taught me that it's a bad idea - I kept hitting the neighbouring strings as there are very subtle differences in the string height apparently.

On the label I first ignored the text in the round stamp, or maybe misread it as Shanghai. Only after the violin had settled in and sounded surprisingly good, I wondered again who made it and looked at the label again, and it says HsingHai - which I understand is a major manufacturer of all kinds of instruments, famous for pianos among other things.

So now I still need to rehair those bows:

 

This is the fifth violin I have managed to make playable (see details and links below). Two are now available for anybody who would want to play them - one for free and the other for a fee covering my costs. One has already been rehomed, one I'm playing myself and one stays for family history reasons.

Previously in the pirate luthier series:

violin 1) is the one my late aunt had since the 1930s, which got me started. After restoring it in November 2022, I played it almost every day for 14 months, until number 5) showed up.

violin 2) is a Stentor student 1 (a very widely used brand of cheap fiddles available everywhere and still being produced). It has a fault that is probably not worth repairing, see the blog entry on number 3) below. After stripping it of some accessories and spares, I am now inclined to keep it in a semi-functional state to try out experimental repairs, i.e. use it as a wooden guinea pig of sorts. Currently it is sporting a brand new tailgut which I made from an old cello C string.

violin 3) came from a folkie friend who moved away. I put the soundpost back in its place and it has now found a new home.

violin 5) (donated by a friendly freegler) is my new favourite and the one I currently play in folk sessions.

violin 7) is a skylark from 1991 which I bought on gumtree for £ 10 and fitted with a better bridge. Good enough for folk I would say.

violin 9) is the one discussed above

violin 10) is the broken one with traces of multiple repair attempts. I'm still gathering courage to try and fix that one.

it's WNBR season again!

The UK's World Naked Bike Ride season kicks off in two weeks time with the Portsmouth Ride, so I'll compile some relevant info here. I typically get the tip-offs from this page but don't find its alphabetical order very helpful, so I am sorting everything in chronological order, as long as it can be reached from Oxford in a day trip using public transport (also including some rides abroad in places where I might be passing through by coincidence). No guarantee, obviously, do check other sources and local info.

As time passes and rides happen, I'll update the list with links to photos, press reports, and whatever I find about them.

25.5. Portsmouth
2.6. Oxford
8.6. London
9.6. Brighton
15.6. Cambridge; Brussels

rivers restored

Today's issue of Current Biology is a special theme issue on ecosystem restoration with lots of articles on various kinds of ecosystems from rescued coral reefs to land rehabilitated after mining, and general aspects from ecology to finance. My modest contribution is a feature about restoration of rivers, from the reinvention of what was once Europe's dirtiest river (not all that far from where I went to school, so this revolutionary change still boggles my mind) to the removal of barriers in Europe and North America:

a bit of a neck problem

Pirate luthier adventures continued ...

I've had several neglected/abandoned violins coming in recently that were kindly donated by fellow freegle users. This one, number 10 in my logbook, is the first that actually has a serious problem that may be a bit of a challenge, namely a detached neck. Not only that it has come off, but there is a whole crime scene around it with traces of six interventions attempting to reattach the neck dating to at least four different times. Obviously, all of them appear to have failed. Some have involved serious woodworking skills so I am beginning to wonder if there is any special problem with this neck that makes it impossible to attach it?

Let me take you through the whole story - first the crime scene - a 3/4 violin possibly dating from the 1920s according to a labewl attached to the case:

Then, what I think must have been the first intervention is the replacement of the block on the inside of the violin body to which the neck should be attached (but isn't). Somebody cut a little window in the back of the violin to do this replacement and closed it very nicely afterwards. Alternatively, if the neck was broken violently (as opposed to coming loose because the glue failed) it may have damaged the back of the instrument in this area and it may have needed replacing anyways. Actually my current favourite violin, the one I usually play in folk sessions these days, has the same kind of repair and it appears to have worked in that case without any further measures.

But in this case it didn't work and somebody started drilling holes through the heel of the neck and into the block to insert dowels and stabilise the connection. As the corresponding holes show up in the block, I conclude this happened after the block replacement. Obviously, the first dowel may have been part of the same repair that gave us the new block, or it could have been later. Closer inspection reveals that three dowels were inserted at different times (apologies for the blurred photo my camera refused to focus on this correctly):

The one bottom left came first. Then, after this obviously failed, a new hole was drilled partially through the first dowel, and a second one inserted (top), partially overlapping with the circle of the first. Still no luck. Then our repairer drilled a bigger hole and used a bigger dowel (right) intersecting both previous attempts. Two additional small dowels are found on both flanks of the neck closer to the fingerboard. I guess these could have been just reinforcements to any of the attempts above, so I haven't counted them as a separate repair attempt.

The fourth attempt in my counting only involved glue, as the holes left by the dowels are all filled with glue, so there was definitely an attempt relying on large amounts of glue after the repairs that involved the five dowels discussed.

So, well, all of the above failed, and I am left to wonder why. And what to do better. Will try optimising the fit and using the proper hide glue first, but any suggestions welcome.

of larks and skylarks

Chinese violins of the Lark and Skylark brands have a terrible reputation - even though they're probably not all bad. Hence they are going very cheap and I found a pair of Skylarks and a big pile of sheet music all together for £ 30 on gumtree and took the opportunity to find out more about the notorious skylarks.

What I got was a 7/8 violin which I'll present later and a full size one (4/4) which I'll discuss here. It has a lovely label inside with the manufacturing year given as 1991. (I'm not sure what the model number MV--005 means does anybody know? The 7/8 violin that came together with this one has MV--007.)

I'm guessing that the Lark and early Skylark violins that ruined the brand reputation were a lot earlier because this one isn't worse than the cheapest Stentor student model you can buy today. The only thing that needed doing was to replace the bridge which was a bit warped (and also narrower than it should be?!):

but with a new bridge (Stentor from a derelict violin I am plundering for spares) and a bit of cleaning the instrument looks and sounds acceptable. A little bit boxy on the G string but good enough for folk as they say. It still has the strings it came with which may be quite old, so if anybody wanted to play it seriously, they might want to invest in a new set.

I do love the Skylark shoulder rest that came with it, which has a real steampunk vibe:

and it also came in the original Skylark case:

I think the pirate luthier series now needs some navigation aids as I have presented a few different instruments here (and they now have systematic numbers, violin number 9 arrived on the premises this week).

violin 1) is the one my late aunt had since the 1930s, which got me started. I played it almost every day for 14 months, until number 5) showed up.

the Geppert family and associates

Every picture tells a story, season 3, picture 19

Here's a rare group portrait reuniting all three kids from the Dörndorf bakery (Silesia) and their mother as well. But I have no idea who the other people are. Nor where the location is:

So we recognise first from left, young Willi Geppert, then his sisters Hedwig (third from left) and Emma (5th). Their mother Martha Stephan standing between the sisters. The guy on the right occurs in a few photos with Willi (eg here) but I have no idea who he is, could be a cousin? I'm assuming that the woman next to him and the three children are his family but that's just a guess.

As I noted before, Martha in the middle was quite short (147cm) so unless they propped her up, nobody in this photo is taller than 160 cm.

stop plastic pollution

I have written a few features already about the rising tide of plastic waste engulfing our planet. What's new this time is that the microplastics have actually arrived in our bodies and are causing harm to humans not just the environment, and that a global effort is underway to do something about it. So let's hope that this will be a success story like the Montreal protocol, not a 30-year tragedy like the climate summits.

The feature is out now:

the art of alchemy

Alchemy is of course a fascinating subject but also a frustrating one, and I always end up dazed and confused when I try to get into the mindset of the old alchemists. The medieval imagery connected with it, showing alchemists at work, their lab glassware, or their allegorical concepts of the world, may be somewhat more accessible, so I took the opportunity to read and review the book

Art of Alchemy: From the Middle Ages to Modern Times (Wunderkammer)
by David Brafman

which contains equal amounts of glorious images and almost comprehensible text. Now I'm still confused, but at least I have another beautiful book on my shelf.

More about my struggles with alchemy in my long essay review now out:

a lovely hat

Every picture tells a story, season 3, picture 18

I love the hat that Richard the young chemist is wearing in some photos from his student days (or possibly teacher in training, but we're definitely looking at his 20s here), so here comes the official hat appreciation post, first Richard on his own with the hat in question:

I'm getting the impression this is his first adult hat and he chose it half a size too large hoping he'd grow into it? Next we have a photo with his parents (Heinrich the cellist and Maria), also suitably covered:

And then a family gathering that is slightly remote. Maria's mother had died very young and when her father (Heinrich Pfersching) remarried, the new wife also brought a daughter called Maria into the family. That Maria from the other side married a man called Anton Fritz and had two daughters called Maria (again) and Ilse, both born before 1926. All of these "Fritzes" appear in this photo:

Next to Richard and his hat we have the younger Maria and Ilse in front of them. Then to the left Anton and then Maria senior and, I presume, Anna who is a half-sister to both Marias in the older generation.

Note that in 1918/19, after being evicted from Lorraine, 9-year-old Richard and his mother moved in with Heinrich Pfersching's patchwork family for half a year or so, before moving on to Elberfeld. This may explain why he remained close with his relatives in Bruchsal, even though the generations are misaligned - his aunt and uncles are not much older than him and his cousins a lot younger.

gaudeamus igitur

In last week's Every picture story I mentioned the songbook that I inherited from my great aunt Esther. I am not sure whether the Hermann Bender who signed it was the confectioner or some eponymous stranger. The confectioner's wife, Henriette Düselmann was Esther's great aunt. (Is there a technical term for my great aunt's great aunt?)

I took photos years ago and must have shared them on my tumblr book blog (deleted by the Inquisition) but forgot to put them here. So here goes (with a fresh photo of the outside of the book):

Note the biernagels (beer nails) - the book is made to be used on drunken nights in unruly taverns, so these metal bumps are there to keep it safe from drink spills. The text on the cover is from a student song and translates as "Let's have fun while we are young." The song is called De brevitate vitae (on the shortness of life) and is entirely in Latin. (Video with text). I thought it was just a quaint old German thing, but Wikipedia tells me it is today widely used as an anthem of educational institutions of all sorts.

It is the 43rd edition of Schauenburgs allgemeines Deutsches Kommersbuch. The excellent Wikipedia entry seems to suggest that it must be from 1891-1893, as these years are documented for the 42nd and the 44th edition, respectively. Wikipedia also lists the multiple subtle changes made to the frontispiece over the years, so here's my version:

the inscription on the left says somebody used it as a guest of the Tueskonia on May 2nd 1896. The closest match I can find is the Tuiskonia in Munich. I'm not clear about the signature, will have another think on that. In any case it could be a nickname. Below it says "Pension Grenzland" - today there is a B&B of that name in Bad Brambach, on the Czech border, near Hof, Bavaria. Not very close to Munich though.

And here we have the beautiful signature of Hermann Bender, who may or may not be the confectioner. He also signed in pencil on the dark paper facing the inside of the cover, but that one is hard to see and not as beautiful.

From the Wikipedia entry I also learned just now that these two mostly illegible handwritten pages shown below are not specific to my copy. (It had always confused me that this seems to be dated 1858 while the book was printed much later, it contains references to events in the 1880s.) Turns out the original authors dedicated the first edition to the poet Ernst Moritz Arndt (see the printed text above right and below left), and it's his reply that was included in later editions as a facsimile. So, phew, I don't have to decipher that.

menopausal mammals

I knew about orca females enjoying a post-reproductive lifespan (ie going through menopause), but in recent years the number of non-human mammalian species doing this has grown to five, and all of them are toothed whales, which is intriguing. So I took a new paper on the evolution of this trait in whales as an occasion to write about the menopause of whales an women. (I recently had Of elephants and men, so I'd better give poor old John Steinbeck a rest now.)

a confectioner's business

Every picture tells a story, season 3, picture 17

last update: 11.4.2024

Let's go back to the Krefeld Clan - the 13 children of silk weaver Wilhelm Düselmann and Elisabetha de la Strada who married in 1826 and agreed to bring up the boys protestants (like their father) and the girls catholics (like their mother).

Of the 13 children, we have seen child number 7 Karl the foreman (and father of enterprising Julius) and child number 10 August the fireman (and father of adventurous Walter).

I don't think I have any photos of any of the other 11, so if any of the hundreds of descendants out there would like to share some I'd be very grateful.

What I do have though is the husband and three children of child number 9, Henriette Düselmann, who was born in 1843.

In 1863 she married confectioner (Conditor und Zuckerbäcker) Joseph Hermann Bender (born 1840). He has a database entry here, where funnily enough only the sons are listed, whereas all the info on descendants I have concerns two of the three daughters of the couple. Anyhow, here's the confectioner in around 1895 with his son Nicolas, left, both daughters, and an employee called Nik (or possibly Josef Hermann's brother Nicolaus - I have contradictory infos on this?!):

Firstborn child Gertrud married Wilhelm Heinrich Habrich; Josefine married Wilhelm Max Holler (brother of the painter Alfred Holler), shown here:

Each had four children, so the complete set of eight born between 1902 and 1912 is here (maybe around 1915 judging by the size of the youngest standing on the bench?):

And this is a wider family gathering for Pentecost (Whitsun) 1926

Here we have the confectioner's daughters Gertrud (2nd from left) and Josefine (3rd). Far left is Gertrud's husband, Wilhelm Heinrich Habrich. Josefine's husband, Wilhelm Max Holler, is the 6th from left. On either side of him two Holler children, and on the right of the picture four Habrich children lined up.

Open questions: The woman fourth from left is unidentified according to my source, but given the symmetry of the picture with three sisters ligned up on the right, I am tempted to speculate it could be the third daughter of the confectioner, Klara Bender, see below? Trouble is we don't know much about Klara. The 8th person is named as Adolf Peters. We don't know anything about him but note that the grandmother of Gertrud and Josefine, Elisabetha de la Strada, had a brother who married a Gertraud Peters, so there could be a remote family link.

In the ancient Krefeld Clan blog entry I had two other children of Henriette and the confectioner (in addition to Gertrud and Josephine):

9.3. Nicolas Joseph Bender * 22.4.1864 Krefeld

9.4. Klara Bender * Krefeld

Digging up some old correspondence I find that Nicolas moved to Berlin and Klara was severely injured in an accident with a horse carriage.

The database entry reveals a second son I didn't know of:

Heinrich Bender * 30.10.1871

But it shows no marriage or offspring for either of the sons.

So I had the sibling order all wrong,it should be:

  1. Nicolas Joseph Bender * 1864
  2. Gertrud * 1870
  3. Heinrich Bender * 1871
  4. Josefine * 1881

And we still don't know where Klara fits in - the biggest gap to accommodate her would be before Josefine.

Another mystery that's possibly related: I have a 19th century student song book signed Hermann Bender, inherited from Esther the travelling saleswoman who came from the Krefeld clan, so it could be an heirloom linked to the old confectioner, but then again she also bought antiquarian books, so it could be a coincidence. Will have to do a separate entry on that at some point (UPDATE: done now).
