Hi xarax,
Although I believe that all the three methods are related, I think that the one for the Tresse and the one for the DLlocked, are more closely related to each other, because they work in exactly the same way:
One have to have a little patience to "decipher" them, but in this post
http://igkt.net/sm/index.php?topic=4476.msg29355#msg29355 Dan Lehman provides all the details necessary to make TIB any bowline with a simple/standard collar that may come to mind,just starting from realizing the nipping turn directly as it appears also in the finished knot, as when one makes the corresponding no-TIB version,and also he provides the instructions for making four different versions (righthanded + lefthanded x 2 different retuckings) for each bowline one decides to do with this method"a la Bellringer." Contrary to what I commented on that thread, after having fumbled a bit with this method,I also realized that it is quick and easy also with regard to its practicality.
Now, the method proposed by Dan Lehman and the one proposed by James (I like!
) for the DLlocked, they really are not so different:the only major difference is that the first begins directly from the nipping turn and then pass through it the bight or the turn, while in the second occurs Basically that one build the nipping loop around the bight / turn previously built.
So, the second method for the DLlocked corresponds to the option "(c)/(d)" (depends on how it is twisted the bight) of the DL method, while the method for the Tresse corresponds to the option "(a)", but building initially the tresse nipping structure instead of the standard nipping loop.In the same way, in fact, with the second method, orienting / twisting the bight around which the nipping structure will be built , one can get the same four versions of "handedness" / closure of the bowline.
Bye!
