The Troll

See

https://en.wikipedia.org/wiki/Internet_troll


I have been identified as a "troll".  And, from their Norse origins, trolls have been dark and disruptive creatures that pose riddles and eat children.  Now, that my nature has been exposed, I do not have to worry about my reputation, and I can do what come naturally.


Of course, I am disruptive in the same way that Newton, Copernicus, Steinmetz, Curie, Fermi, and Feynman were disruptive;  I tell the truth.  I say things that others should have seen, but did not say.  As an identified troll, I find telling the truth to be deliciously disruptive, and I find telling lies to be calming.


The truth is: that modern spinners have a fanatical doctrine that destroys history just as surely as Taliban blowing up Buddhist statues or ISIS blowing up Palmyra.  I think that if modern spinners had the courage and technical knowledge of explosives, they would try to blow up my spinning wheel because it does not comply with their doctrine.  The have certainly lobbed enough written bombs filled with all kinds of shit at me.


Modern spinners have made a point of trying to write DRS out of history.  SG and AA certainly found 11 spinning wheels with accelerators.  Such accelerators work much, much better on DRS than on any kind of single drive wheel.  If I see an accelerator on a wheel, then I know that it is a DD/DRS wheel. Anybody that has used a variety accelerators with a range of flyers knows this.  Modern spinners that do not know this, do not know their tools, and this is the key.  Modern spinners have not bothered to learn about their wheels.  They have not done their homework.  The spinners that lobbed all those written bombs at me show me that they are as ignorant as the narrow minded fanatics in the Taliban and ISIS.  it shows me that they have a doctrine that is divorced from the physics and mechanics of spinning. It is that doctrine, that lie, that calms modern spinners.

GW 2

These days, I do not keep a great wheel.  I do have 2 motor driven spindles and 2 spindles that fit onto my treadle wheel.  None of these are as impressive to look at as a GW, but they are faster. And, they all allow me more use of both hands for drafting true worsted.

The motor driven spindles are easy to pause or stop, but hard to reverse.  Therefore, I had to learn how to wind-on with the spindle going in the same direction as when spinning.  It can be done, the answer is "out there", and I have no interest in teaching driven spindle technique.

If one does not have to reverse the spindle, then one does not have to stop, or pause the spindle, and the spindle can rotate continuously in the same direction.  One CAN spin a entire hank of single on a great wheel without ever reversing the wheel to wind on.  This can be much faster/easier than reversing rotation to wind-on depending on the inertia of the rotating system.

Nevertheless, the spindle must be slowed at various points in the spinning/drafting/wind-on process. Even though the spindle/wheel always rotates in the same direction, the slowdown/speedup cycle wastes energy. And, the wind-on cycle slows production of yarn. 

A spindle on my treadle wheel can insert twist many times faster than the flyer/bobbin assembly,  but the DD flyer bobbin assembly will spin and wind-on much more yarn in a minute or an hour or a day.  One of the motor driven spindles can insert twist many times faster than either spindle on my treadle wheel, but net production of single is not much different. Net production of spun yarn by a spindle is limited by the nature of its cycle, rather than by its peak speed.

A DRS flyer/bobbin assembly is the fastest hand spinning device for most natural fibers. Ring spinning can be faster for silk, but that is a specialized application.  Yes, those old double drive spinning wheels were the fastest way to spin.  They used the two loops of the drive band to synchronize the rotation of the bobbin and flyer to insert just the right amount of twist as the yarn was wound in at just the correct rate for the inserted twist. They did not have the drive band slip that is built into modern double drive wheels.  The result is that a double drive wheel without drive band slip that can produce singles much faster than a great wheel.  This is a truth that you have heard before.  It is just that all  modern DD wheels do have drive band slip and thus, spin more slowly than a GW.   In fact, a DRS flyer/bobbin assembly can produce true worsted spun yarn 5 times faster than a great wheel.  Every sock knitter should think about that.

And, since DRS is faster, sock yarns of more and finer (true worsted spun)  plies are possible.  These are very nice yarns that are simply out of reach of even the best spinners using a GW.  The use of DRS opens up spinning true worsted 5-ply gansey or even 10-ply Aran yarns.  And, it makes spinning true worsted warp for the loom much more feasible.

 On the other hand, a DRS flyer/bobbin assembly requires real skill to setup and maintain. I have seen two old DRS double drive wheels where the original DRS ratios had been "repaired", and the wheel converted to  modern standards.   As a result of the repairs, they could spin lower grist yarns, but could only do so --- slowly. These had been true collector's items and the owners were very proud of how fast they could spin -- if they only know how fast those wheels had been originally designed to spin, they would have been agast!   The difference between these wheels as designed and these wheels as "repaired" was only millimeters, and yet it made a huge difference in their performance. If one can teach the basics of using a GW in a 4-day workshop, then I would say that one could teach the basics of using DRS in a 4-week workshop.

Yes, Holin, my old Ashford can spin/ply a 500 yd hank of sport weight, worsted spun, 5-ply (gansey yarn) in an easy day.  How long does it take your GW?  In less than 14 hours, I can spin/ply a 500 yd hank of  worsted spun, 3x2-ply cabled, 1,600 ypp "sock yarn".  How long does that take your GW?  Shall we set up a demonstration in front of a judge and jury?  I want spinners like Judith MacKenzie and Stephenie Gaustad who know, and appreciate,  worsted spun yarns involved.

I have only been spinning for 6 years. (And, I was sick with Lyme Disease for much of that time!)  How long have you been spinning?  What will I be spinning when I have spun as long as you have been spinning?
