It is possible to hand spin worsted yarn using a "long-draw" technique. ( Not what you have been told before, now is it? )
It requires special tools. One must have a DD wheel with the appropriate differential rotation speed (DRS) and bobbin core size to insert the correct twist and to take-up at the correct rate. It requires well combed top on a well designed distaff.
It only works at fairly high grist (9,000 ypp and up depending on fiber), and it only works for spinning at a brisk pace.
The process involves the drafting hand teasing fiber out of the sliver attached to the distaff. The fibers are kept under some tension as they stream into the drafting hand where they are spread to form the base of the drafting triangle. The tip of the drafting triagle is a narrow ribbon of fibers feeding between the forefinger and thumb of the pinching hand. The drafting hand and pinching hand are moved together and apart for precise control of the grist, The pinching hand keeps enough pressure on the tip of the drafting triangle to keep the twist from traveling up into the drafting triangle, but not so much pressure as to stop the continuous stream of fibers through the "pinch". The thumb and forefinger of the pinching hand move back and forth to facilitate movement of the fibers through the pinch.
With lower grist singles, it is not possible to stop the twist from moving up into the drafting zone. Without a distaff, it is not possible to get the fibers aligned as they enter the drafting zone.
I had though the technique possible shortly after I started working with controlled DRS systems, however, I had not been able to make it work. The addition of a distaff was required to actually make the concept work.
The process is very fast.
Pictures and details to come.
