I have been plying yarn for my Shetland gansey. Some of the singles were spun last winter before I built the Hot Rod and some after.
Running the singles through my fingers, I am impressed by the consistent fineness of the singles spun using the Ashford high speed whorl and bobbins with whorls that provide the proper DRS (differential rotation speed) for the grist of yarn being spun. While the Hot Rod certainly allows me to spin faster, singles spun on it tend to drift in thickness. For example, singles that I intend to be ~9,000 ypp end up with portions being closer to 7,000 ypp or 11,000 ypp. I think this is because with the small whorls, a small change in anything changes the DRS. While the standard Ashford high speed whorl is twice as large, so the same change in that system makes only half as much change in its DRS.
Anyway, I am going to move toward larger whorls so that I have better control of my DRS. I have not decided if I am going to do that by putting an accelerator wheel on the Traddy or if I will buy a 30 inch wheel.
Most of last week, I had the Ashford Lace Flier (ST) on the wheel. First and foremost, I do not think that there is any question that a good bumpless driveband (per Amos) delivers more power than the Ashford Turbo driveband (clear stretchy plastic). 2) Fluorocarbon leader material (fishing line) makes very good brake band material for spinning very fine yarns.
As long as we are talking about spinning fine, see the Bothwell Spining results at http://www.bothwellspinin.com/spinin/files/LongestThreadResults_2011l.pdf The winners are spinning singles up in the range of 100,000 ypp or 176 hanks/ lb. The winner, Jan Zandbelt, currently uses a Louet Julia, but in 2007, he used a Majacraft Suzie with 1 gram of brake tension and custom made ultra-light weight spinning bobbins. Of course, that contradicts my thoughts about DD being better for spinning fine. Or, does it?
I do not spin that fine. I do not try to spin that fine. I do not need singles finer than about 27,000 ypp. I aim to spin my finest singles at ~90% of their spinning count. Thus, Polwarth has a spinning count of ~ 62, so I would aim to spin it at ~ 31,000 ypp. Zandbelt spins it at 88,400 ypp.
Does that invalidate everything that I say? I want yarns that knit up into fabrics that I like, and I want to produce those yarns with a minimum of effort. Zandbelt wants thin yarn for contests. He says that "Patience" is important. We have different goals.
However, I am arrogant enough to think that if I wanted to spin Polwarth into a yarn that was too fragile for any practical use, I could. I would approach the problem by making up a DD spinning bobbin with a DRS of 1.01 and a bobbin core diameter of 0.625". I think that for that low a DRS, I would use the regular Ashford DD flier whorl, which gives me a bobbin whorl diameter of 1.73". We are talking a bobbin speed of 1,200 RPM. My bobbin has not gone that slow in ages. It would take all weekend to spin 10 grams. "Patience" is right.
