Are there any other acceptable knots for use with flat tubular webbing?
It would be nice to have something with a high break strength and easy to untie.
...
Flat webbing seems to be a mess for something like an EBDB, but I could be convinced.
Others?
I imagine the simple overhand loop is just fine, but this is fun to discuss!
Nice to see "flat tubular webbing", vs. the traditional contrasting
"flat" vs. "tubular" --better, IMO, for "solid" to be the contrasting
adjective, as all webbing is flat by definition!
You might simply insert some suitably sized dowel/pipe into an
overhand eyeknot for getting easier untying.
The
EBDB is not something that should be thought of, as its
reason d'etre is one of security, primarily, and in rope not tape.
I've read someone assert that a
bowline on a bight is stronger
than the
overhand eyeknot, but I'd think one could use some
better
bowlinesque knot, aiming to pad the flat material just so.
I'll suggest trying what I call the
"symmetric fig.9 eyeknot" --a knot
that is topologically the same as the better-known
fig.9 but takes
a symmetric orientation, and one that enables easy untying.
Here's a verbal illustration:
1) fold the rope into a bight running rightwards (ends left);
2) orient this bight so that the flat side faces you (narrow sides
up/down ; broad sides facing at/away from horizontal view);
and have the tail on your (viewer's front) side --towards you,
loaded end behind;
3) now, make a 270-degree loop by bending the bight around
anti-clockwise around and down behind itself, keeping the
tail on the inner side, loaded part exterior (so, where this
bent-around part crosses behind itself, it will be the folded
tail that could touch the horizontal loaded part);
4) bring this bent-around bight front and up through the
loop just formed (this will complete and
overhand knot),
keeping the tail interior;
5) keep bending the bight anti-clockwise, tail part interior,
around itself and down
in front of the horizontally
disposed standing part & tail-end and out through the
loop aspect formed as the bight was reaching up to complete
the
overhand (if one were to do this
behind the
horizontal parts, you'd form a
double overhand).
Dress the knot by reducing material/span of the bottom
bent-around path and smoothing things out in general;
settting/tensioning is going to do some various crunching
and distorting the flat aspect of the tape in places, but
that's to be expected.
The general appearance of the knot is that the twinned
SPart & tail coming from the left reach into the knot and
curve upwards, and the twin eye legs similarly come in
from the right, almost like contestants of arm-wrestling.
I find the knot VERY easy to untie --that bottom span
just doesn't tighten (and why one wants to work out
excess material there), in most materials (ack, it DID
in the very slick HMPE 12-strand rope --darn tight!!).
I have no idea about the strength of this knot, but surmise
that it's decent; consider, that in the
overhand eyeknot,
the material that "collars" the mainline is itself being loaded
by the eye --it's the eye legs--, whereas in this knot, that
material collaring the SPart+tail and in opp. side the eye
legs is *passive* --it's simply there, resisting, not loaded.
