Local newspapers
Who said that local newspapers mostly contain local gossip?
Well, at least that is what I have always thought. So today I went to the local archive to read Nya Wexiö-Bladet for 1847 - the year that Mlle Granberg was touring the county giving classes in double-spinning.
I anticipated coming home with lot lots of "gossipy" information, such as Joahnna Månstdotter and Lina Andersson did attend the class in Lenhovda, and after only a week were able to spin 3 "pops" (knäpp) weighing only 2 "lod", or somesuch. Hopefully I would find advertisements and, and...
But. No such luck. In fact, almost no luck at all.
I found a few names, but those all belonged to remarkable spinsters from before the classes.
I found no advertisements at all (for things relevant, such as the classes themselves, spinning wheels, "modern" hackles...). Also I found nothing about the actual classes, not even the slightest mention!
What I did find was a kind of "morality", in the form of a conversation between "Mrs X", "the girl" and "the uncle":
Mrs X didn't want to send her maid to the spinning school, but the girl (niece of Mrs X, in fact) was going, because the uncle had said it was a Good Thing To Do.
Enters said uncle, who proceeds to tell the Ladies why [double-flyer] spinning school was such a good idea: it was "ancient" (had been used in Brabant for over 100 years - imagine that!); it would give work to paupers [my comment: why couldn't they get work spinning on a normal wheel, if spinsters were so sought-after?]; he gave a long lecture about the economics [interesting, but it will take some time until I can untangle all the various measurements used]; last, but not least: the Ladies ought to resume the responsibility of being Role Models.
Nearing the end of the economic lecture, Mrs Y enters. She gets all interested, 'cos that would mean she could turn away beggars without any remorse. Mrs X is nicer, she doesn't like to turn away hungry women without giving them something to eat.
The girl is excited, says she wants to go. [But that was her intention from the beginning]
This was quite a long article, but it ended without any mention at all about how to enrol, who was organizing the event(s), when and where they were to take place.
(Ok, so there might have been mentions I didn't see, but if so, it was in the middle of the "running text" - no advertisements, no "marketing".)
Maybe it wasn't so strange that (at least) one of them had to be cancelled due to low interest? I have found, in another publication, that four or five *were* held, one of them with more than 20 students. There were students turned away because of lack of double spinning wheels. (If you follow that link, don't tell anybody. Taking pics was allowed; showing them is not. Makes sense?!?)
So here comes a "legitimate" picture:

How to spin better linen yarns
Many authorities "of the time" assert that yarn spun with "the new method" (ie with a DFW of the Mager type) has a much, much better quality - as if consistent grist and twist come automatically with the wheel type. (Maybe it does... after all, I haven't got mine operational yet)
To let you all know as much as I now do, I took a stab at translating the first part of the Book with the Hopeless Title - the part that should instruct us all how to use this famous wheel.
(It can be that you, too, become a bit disappointed with the contents. But I assure you: this is all there is!)
The first part, same as the other, is now available in .pdf-form, the translated variant here with text in both Swedish and (my attempt to translate it into) English. The plate is on the very last page. (Comments on the translation(s) are most welcome!)
There is also the "original" (transcribed, some sort of Swedish) - found here. The drawing is on the last page.
For my local-ish Swedish friends: do you know anything about the Gårdsby Lin-Institut, at Gårdsby outside Växjö, that was in existence 1811-1827 (or -28)? There is a rumour that they used double flyer wheels there, too, but as the Mager type was not known until 1843, I would be very interested to know what kind of DFWs they were using.

How to build your own double (or more!) flyer spinning wheel
As told here, I have borrowed the Ekenmark book with the hopeless title (Afhandling Om Den förbättrade och förenklade Nya Magerska Linspinnings-Methoden, Jemte En wida ändamålsenligare Method, för så wäl Dubbel- som Enkelspinning, med förändring af en wanlig Spinnrock, både för en och flere personer på en och samma gång, hwarigenom den motswarar nyttan af 4 serskilta wanliga spinnrockar, Äfwensom Om bästa sättet, att få linet genom sjelfwa Rötningen mycket finare och mjukare, så att det derigenom blifwer ojemförligt ändamålsenligare till båda Spinning, garn och wäfnader, än hwad genom den wanliga Linrötningen och torkningen kan åstadkommas.
Utarbetad Af GUSTAF EKENMARK och HUSTRU
Med en större Lithografierad Planch
Stockholm Tryckt hos Lundberg & Comp. 1848)
I have also transcribed it (gothic print...), probably with some mistakes here and there.
Today I can offer anybody nerdy enough to want to know how to alter an ordinary saxony type spinning wheel to accommodate as many as 4 flyers, without "compromising" the original wheel: there is one .pdf here with text in both Swedish and (my attempt to translate it into) English - no light reading this (I doubt I have ever encountered sentences as long as in this text... hard to read in Swedish, even harder to make some sort of sense in English). This file has a couple of illustrations enlarged from the drawing (which is on the very last page).
There is also the "original" (transcribed, some sort of Swedish) - found here. No extra illustrations, but the drawing is on the last page.
If I end this post with "enjoy!" - would you think I'm having you on?!?

The plot thickens...
Thanks to my friend Åsa I now have a plan! (A "plan" as in - well, you'll see)
It turns out my DFW is a modified Mager clone.
(Who Mager is? Wait and see, I'll have to read the whole book first.)
It also appears that is it a flyer-lead, bobbin-drag (is that "Irish tension"? I always get confused about the brake type wheels and their terminology).
But there is still one mystery...
Here is the overview of the construction drawing:
The tensioner pulley should be mounted top-down, and apparently wedged in place. (Though the wedge can't be seen, but there is no other fastening shown either)
Two detail pics:
This explains two mystery holes I have - where the green arrow is, mine has holes on both sides. BUT: there should be holes where the red arrow is - holes pointing forward.
On the right-hand maiden (is it called maiden even if it is an integral part of the structure?) there is a hole on the outside, but on the left side there is no hole at all.
(And: "maidens" or "uprights" - they seem to be one and the same piece of wood going from the table to the top. No way these "maidens" have been/can be made to turn!)
Speculating: can it be that there is just ONE brake-band, braking both bobbins at the same time? It would, I think, make the adjustment easier?
(And I still haven't made the axle retainers, so I can't try it out. Yet.)

What I have been doing - nerd alert
It all started with the DFW (Double Flyer Wheel).
I wanted to know where it came from (or, at least, from whereabouts in the country this kind of accelerated driving was known). I had seen something in a (borrowed) book - had to buy it for myself. Was sort of disappointed - there was a wheelwright mentioned, that much was right, but, as it were, only in passing. He had a name and a year (Abraham Hedman, 1738), but that was all there was.
I (thought I) knew I had seen something like it, many years ago, in a museum. Thought I knew which museum. Wrote to them. Wrote to several more museums, while I was "at it". Result: nothing, nada, zilch. A month later, ONE of the (by now 6) museums answered: "I don't have time to go out in the storehouse to look".
Meanwhile, I got a couple of obscure books on ILL, one of them very dull-looking: Den Ångermanländska linslöjden, en historik. (The linen works of Ångermanland, a history). It is a dull text, but once I started to really read it I found lots of, hm, nuggets(?). And lots of food for nerding...
So, here, friends, goes:
Definition of "prime linen": as you (probably will not) remember, "prime linens" come in many classes. They were (at least most of them) 1 1/2 aln (3 ft, or 88-89 cm) wide.
For class 1 there were 2720-2920 ends (or 30-32 ends/cm); for class 8 (which was NOT the finest seen) there were 4120-4 320 ends (or 45-48 ends/cm).
The History book contains some well-described examples, complete with old (and obscure) weights-and-measures.
So I got out the calculator...
One example was described as 39 alnar, 4 1/2 skålpund; 3600 ends, woven in 2299-dent reed.(If I did my calculations right, this means the cloth was 23,2 m long, weighed 1,9 kg - which would translate to 81,9 grams/metre fabric).
OK.
3066 ends x 23,2 metres of cloth = 83 520 metres of warp yarn.
But we have a weft, too. For convenience, I assumed 40 picks per cm (warp density comes out as 40,5) - which gave me another 83 500 metres.
Which gives a total of about 167 000 metres per 1,9 kg of weight.
Now, linen is numbered in Nel (Number English Linen, I believe), where the number tells how many skeins of 300 yards is accommodated in 1 imperial pound.
One yard is 0,91 metres, so 300 yards = 274 metres (rounded), which means we have 167 000 / 274 = 609,5 skeins - let's round a bit carelessly, say 600 skeins.
As an imperial lb (of today) is approx. 0,45 kg, we can go on: ( 600 / 1900 grams) x 450 = 142 (rounded)
which means this particular cloth was woven with a linen singles (*all* "lärft" is singles) of a number somewhere in the vicinity of 140/1. Handspun.
I did several calculations, approaching from different angles, 'cos I was thinking I had made a decimal error somewhere.
But - all of them came up more or less the same. There were several examples described, and they all came out with a yarn count between approx. 120 to 150. Handspun!
A picture from the book, divided in two to make it possible (I hope) to read the writings.
The caption says, roughly;
"These two photos show the strip, with thrums, cut off from the cloth for which Catharina Andersdotter got the Illis Quorum [a royal medal]. The cloth is of the seventh class, is woven through a weaving reed of 2 200 dents, contains 40 knots, or 4000 ends of warp. Every square centimetre thus counts to 40 ends of warp and circa 37 picks of weft. We have found this linen strip in the royal archives [... something "administrative" I can't translate] 1808 - 1811."
I wish... Or, on second thought, maybe not :-)
But the DFW?
Nothing much. This book tells about several "spinning schools" and some competitions - it seems that the DFW spinners always won, but that did not convince "the people". One of the arguments was that a DFW is harder to spin on (heavier to treadle, needs more concentration), and therefore, even if you are more productive/efficient for the first hour(-s - the competitions were 2 hrs), you can't spin for as many hours as a "prime spinner" usually did. Right or wrong?
Anyway. I still don't know anything about my DFW, it still doesn't work (too cold to do what needs to be done on it, the workshop is unheated) - and the only accomplishment I have done is to amass a lot more "worthless knowledge".
Here is another picture from the book:
which shows another principle for a DFW: one MOA, two flyers. Therefore it has to have two drive bands, I think - and imagine tying two drive bands so that the tensioning works for both, at the same time...?!?
Waiting for more ILL books, and perhaps I have to do some "hands-on" museum search, and...

Putting on the tension
The double flyer wheel is now dusted, and the wheel that drives the flyers can be taken out. So far I haven't been able to get off the bent nail that holds the other wheel in place. Of course that nail sits on the treadle-side of the axle... It looks like I may have to saw it off.
The dead leather bearings for the left flyer are out (and some of the paint with them, but that couldn't be helped). I think I probably will have to change the other (painted) bearings, too.
The left flyer is now tied in place with cords, to make trying out different placements of the (probable) tensioner possible.
There are two possible ways that I can think of.
Either the tensioner was correctly mounted as it was (coming up through the frame). As it can't be raised enough to lift the drive band, the drive band has to be threaded through the "tensioner" before knotting, and as the tensioner has only one pulley, this is the one possible path:
Or it wasn't correctly mountetd. If the tensioner is mounted the other way. It can then depress the drive band to create tension - but both turns of the band have to go under the pulley, which doesn't look right, either:
Any suggestions?
I have also found that the right-hand distaff is not original. The right-hand finial (the non-threaded one) is "clumsier" than the other (see pics in the first post), the distaff arm is slightly thicker and the distaff istself has too many knife marks (it has been carved after the turning).
I have, of course, tried to find pictures of DFWs.
On those which have included distaffs, all of them have had only one. Why is that? To me, it made good sense to have two: even on the most perfectly dressed distaff it could happen that the spinner got hold of "both ends" of a fibre?

It was a nice and sunny day...
and we decided to take a little trip. Once we reached the destination, it was much colder and windier than at home, so the walking was cut much shorter than we had thought.
When we saw the sign to a flea market we hadn't been to, we went there instead.
On top of a shelf I spotted something
It lacked one of the flyers, the paint job was sloppy and it was too expensive for a decrepit, albeit interesting, spinning wheel. Then I spotted the other flyer, found that the bobbin turned freely and the drive pulley screw was not rusted - and it was threaded for spinning S.
So I took it down.
Everything that should turn, turned. Some things not supposed to move, moved a bit too much, but on the whole, it seemed to be (nearly) in working order.
It came home with me.
On further examination, the paint job was more than sloppy, and also consisted of at least two different paints. The outer white flakes, under that there is another (whiter) white. In some places the inner white has flaked, too - there seems to be a reddish paint under that.
At least the outer white was painted on without disassembling, but I managed to unscrew the flyer assembly with patience and some grease.
The missing left flyer's what's-it-called (the leather pieces) will take some fiddling to replace, as they, too, are "painted in".
Also the drive wheels will not come off, because they are secured in place with nails in the back, and one of the, hm, "stops" on the front is missing, too.
The "accelerating" drive wheels are interesting. I have seen something like this many years ago in Ångermanland (which, perhaps, tallies with the "prime linens"... Grenander wrote some about double-flyer wheels, but of course I have returned the book now. Maybe I have to borrow it again...). If I measured correctly, the fast wheel has a ratio of 2,5 compared to the slow.
I suppose this is the tensioner for the drive band. It moves freely, fastens with a wedge. (Hmm - wedge? Really?) But how it the drive band supposed to go - over or under? If it goes under, it is difficult to replace, as the pulley doesn't come out?
And, at the back there is this little thing, about 7-8 cm, pivoting not-quite-in-the-middle. What can it be?
The wheel has a couple of reparations done to it - one of the flyer uprights has a piece replaced, one of the flyer uprights has a new finial and the distaffs are slightly different.
And the flyers are painted, too. Even the hooks.
