Exploding Marlinspike Bends
« on: March 23, 2017, 05:17:53 AM »
Hello All!
I've been exploring what I am calling "exploding marlinspike bends": methods for joining 2 lines including a rod or pin such that pulling the pin releases the lines completely.
See ABOK 392, 1494, 1521, 1522, 1523, 1524 for examples of toggled knots, although I think only 1494 and 1523 meet the "complete release" requirement (not leaving a loop or eye).
Attached are pictures of one version I have come up with (single and double). 

Anyone know any others? Are there any other versions of this type of bend out there? Is there a better term to describe these types of bends? (Exploding toggle bend?)

(Apologies if this has been discussed elsewhere, I did a quick forum search and didn't see anything on this specifically)

Hi ATS  and welcome,
please have a look at
http://igkt.net/sm/index.php?topic=5478.0
The terms "toggled bends" were used too.
About your first bend I would reverse the ends of the black rope (I mean Standing Part (not visible end) and Working End (short visible end)  reversed).
(Perhaps I would reverse the ends of both ropes on the second bend too).

Ciao,

Note that in your upper image (the simple knotting)
the form is asymmetric, as the read tail is pressed
into by the red SPart, whereas the black tail lies
away from such trapping/pressure.

Now, to what purpose are such things made?!
(Perhaps some uses would want the toggle to be aligned
with the axis of tension, not perpendicular to it!?)
