Here is a better video of how I spin. From over my left shoulder:
And from over my right shoulder:
The fiber is an indifferent prep of Shetland that somebody gave me, and I fixed. The grist is in the 11,000 ypp range, and the flier rpm is ~500. Twist is in the range of 12 tpi. Twist and to a lesser extent, grist is set by the DRS (~1.017 with a bobbin core of ~5/8") of the flier/bobbin assembly. Thus, I can switch bobbins, and bingo, I have right twist for 14,000 or 25,000, or 50,000 ypp. All I have to do is make sure the grist is right for the twist. If I need other grists, I make other bobbins as in the last post.
The main thing is that this is a continuous process that produces a true worsted single. Note the use of a distaff. The distaff is necessary to keep the fibers just behind the drafting zone aligned and parallel. The fibers are fully aligned as the twist enters them. Of course, these video sequences are much slower than I normally spin, but you can see there is minimal hand motion, so that my hands can keep up when spinning much faster. This technique is a very fast way to produce a true worsted yarn.
These singles will get cabled up into 8-ply (fingering) for a sweater. I insert some slubs so you can see the progress of the single. In the second video, the twisted single is invisible at this resolution. Sorry about that.
