More on the hot rod wheel

My loom uses a warp tension system that employs sliding weights to vary the tension.  This put me to thinking that I could adjust the tension of the drive band on the spinning wheel by sliding the weights rather than changing the weights as I have been.  It works.  It complements the gang whorl system.

I just slide the weight  hanger from notch to notch on a lever attached to the MOA.
(The holes support a yarn guide for winding off ,)

Thus, I avoid running out to the garage to get different weights.

Overall, now I am satisfied with the spin system' performance.  At this time, this wheel will spin about as fast as I can draft. It meets my needs.

Three years ago, between slippage and vibration,  the new stock Ashford had a maximum twist insert of under 1,000 rpm for the DD & ST flyers, with the lace flyer perhaps 30% faster.  All in all, production speed of 10s (5,600 ypp singles) was under 200 yards per hour.

With Alden Amos's wonderful, low vibration fliers, gang whorls, and adjustable weight system, the system can now be run at well over 2,000 usable rpm on a sustained basis. This means that 10s can be easily spun at 350 yards per hour, and a uniform, knot free hank of 560 yards produced.   40s (22,000 ypp) can be spun in the close range of 200 yards per hour on a sustained basis.  While, I exceeded this speed with the stock Ashford flyer and the very high speed flier whorls that I fabricated last year, then there was more vibration resulting in lower quality thread and spinning on that gear was - more work.

While some of the increase in speed is improved skill, Istill use the stock Ashford flyer/bobbin assembly for plying (because of more capacity).  So I have the gear out on a regular basis and 1,000 rpm is still about as fast as it can go.  While I certainly did learn to spin 60s (30,000 ypp) on the Ashford lace flyer, that is much harder and requires more skill and concentration than spinning 60s on this system. With the current system of Alden's fliers and weight tension, 80s can be spun at a good pace.  More, I cannot ask of any spinning system.

As currently configured, I do not see any advantage to e-spinning, and I have re-purposed my e-spinner to a prin winder.
