FINDING A NEW DESCRIPTIVE (as opposed to "attributive") LABEL FOR THIS
SENNIT PROPOSED BY JIMBO
I'm honored and flattered that you keep using my name.
Could you post this on your page?
I'm flattered that, as a shorthand way of talking about it, you've
started hanging my nickname on this bit of kinkery. However,
I'd hate to have that "stick", at least without some demurring!!
Maybe we could start
calling it a "Spring Sennit"... Or a
"Self-Helical Sennit"... 4-Strand Helicoid Sennit works for
me, if you recall our earlier discussions of this
wee bit of knot magick... Plus it makes people aware of the
between a Helix (a line) and a Helicoid (a 3D helical
Obviously I'm open to suggestions!
Not that I'd seriously object to joining Mr. Walker!! But not
without at least asking for a better name for this.
is there anything
besides "Jimbo's Sennit" that names
Just asking. I'm fascinated by the discussion!!
It would flatter me to be remembered, but I can't sit idly by and
let that happen.
Besides, it's the
Adjustable Ancient Sling
that I actually DID invent "from scratch".
I got too much of this from TIAT to take full credit.

TIAT, IMO was the guy who gave publicity to this sennit algorithm plus
bizarre IMO nothing more than an astute commercial gimmick for me)
label but I will never believe
that he was its 'inventor'.
It is a much too simple algorithm not to have been found before by
several of the so
many knots tyers since humanity began playing with rope. His
proposed 'avatar' of this knotting algorithm is soft, without
any mechanical special characteristics,
have very special mechanical characteristics and in all what I have
seen this TIAT person
did not even begin to hint at that.
If a rose grower
pre-existing takes a pre-existing rose and with much
a new mutation from it he owes nothing to the rose diffuser of the rose
he starts with since then it is a completely different flower that
For my part I see this sennit that you offered as a WHOLE DIFFERENT
the one shown in
and anyone with functional eyes and brain can easily see that.
Still it would be nice to have some proposal if only just for the fun
I tend to favour "descriptive" so I am all for :
self-conforming helical spring sennit
or fancy name
Transformer helical spring sennit

title New creation/invention from Jimbo
Jimbo very recently ressurected his project of tutorial and he wrote to
a number of us ( Don, Jimmy, Joe, Roy and myself ) asking if we could
test it [open quote]

Here is my test
using this tutorial.
I started with two equal length,

Jimbo has really surprising MECHANICAL
by a particularly tight setting ; this is the point that here
is the real novelty as the knotting algorithm is so simple
that anyone in the long past of
knotting could have
invented, re-invented it a thousand times, no particular genius in it,
or as Desmond Mandeville named them
: "trambles".(REEF...REED....SEED...SHED...SHOD... SHOT...SNOT...KNOT
, one crossing change at a time and see if
the knotted structure still makes sense ). No special intelligence
needed, just perseverance and
paper and pencil to take notes.
I have been appraised by several correspondents of two claims
that this was JD TIAT
invention of someone called JD TIAT and not at all Jimbo's.
Two remarks :
1/ As far as I know Jimbo never claimed to have invented the knotting
algorithm but only to
have obtained/discovered particular mechanical properties
that were previously unpublished.
2/ Just as Nature use co-evolution, findings can occur independently,
in particular with a so simple knotting algorithm.
Now for the subtle and not so subtle allusions to possible plagiary (I
DO NOT take very kindly to that )
FALLS by TIAT (who cannot be the certified inventor of this
the very best, its diffuser)
the worst observer will be unable to see the astronomical MECHANICAL
difference in behaviour between this STRAIGHT
and SOFT Endless Falls
structure and Jimbo
its very peculiar behaviour.
A very simple observation clearly show that
one structure, Endless Falls,
is LINEAR and rather SOFT while the SPIRAL SENNIT is an HELIX which is
UNDER TENSION , sufficiently so to induce a sort of shape
it is holding power.
The fact that a very tight
setting could give the structure some quite particular
mechanical characteristic is here the real
finding that apparently fully escaped JD attention ( just look
at his very
soft and linear knot.)
As for this other proposal as source for a
You need to be blind and know nothing about knot tying to confuse this
knotting algorithm with the other one.

lying from Jimbo and myself.
