it’s at least beginning to work.
because ash just wasn’t taking up on the ply and i was pretty much turning the bobbin by hand. i skeined it up and, of course, it twisted badly in the Z direction. after restringing the rear spring an inch or so higher so i could actually tighten it while plying, i got this:
this skeined up to 17 yards with no visible ply twist. here are the two skeins, for comparison.
laughable, of course, but then they’re supposed to be. i spun up nearly every stray scrap and, remember, this is all the various weekends’ worth of trial and error, not just today’s, added up to 29 yards of definitely thick and thin yarf. but. hey, i’m on my way!
