By the way, the single strand moving through the loops is less of a concern because its abrasion point is not constant.
So one would think. But Ashley gives a supposed traditional method
to break twine : pull it sharply over itself @#142-3 ; when I tried this,
just once, it was the
moving cord that broke (!!?). And one
rockclimber reported doing *StairMaster*-like sawing of a climbing
rope through an anchored 1" tubular nylon sling : the rope broke,
and a battered sling remained! YMMV?
But, in any case, both parts might benefit from doubling/widening
the sheave.
You were right to question the ability to equalize eyes --I gave it a quick
try, and I wasn't happy with the result.
The simplest way --though hardly as quickly done & then shaken undone(!)--
might be to use a *
doubled*
Sheepshank (AT LAST!), as some
sources suggest nearly (but for the doubling, i.e.).
Now, the nipping turn might not get the twist of the eye to secure
it, but the doubled eye-bights also impede capsizing; the other turn
in the
Sheepshank helps keep the enclosed
TWO bight-eyes from
shifting and making one longer. I.e., form your double-eye turns
around the had of the desired size, and half-hictch-nip each end,
using the one end qua double-eye for the trucker's hitch.
QED !?
