Ahhhhh! I gotchya.. think i paid 30-40 cents for this 3/8ths..
Which leads me to another question..
Wtf is going on with my endless loop splice.. am i supposed to be doing a long taper on the x-over? A short taper you just cut off at an angle? Or am i going about it all wrong & need to follow Samson's end to end 12 strand directions where one side of the loop will end up way bigger than the other?
I been going at it with the 12 strand e2e instructions in mind, except I'm not removing 6 stands on each side after the brummel because there isn't one in this case.
I swear I've completed this type of x-over sucsessfully on a ton of other splices, i don't know why this one is blowing out. Maybe this is an additional reason as to why we never see T-rex used on e2e's & loops? I have noticed it frays out way worse than Tenex tec, Yale Optimus, Ice Tail, etc.. & maybe that wax us allowing it to pop out when manipulated over an extreme angle (the carabiner i worked the splice over to try and smooth).. IDK.. just a theory.
In the picture it looks like i had the lengths wrong, they were correct at first, i just saw what was happening & pulled them out... but wtf.. this thing went crazy.
Edit Again - Ok so i just deleted the first & second edit.. I've finally figured out what was going on with this scenario & I'm going to explain for anyone else as this was very very frustrating...
The problem i was having with this was that I had not tapered enough. If you look at most directions for end to end splices you are not getting the full picture to complete an entire loop, at least not in a way that I'm used to seeing them. In other words, unless you are content without having the tails overlap each other.. Also, the suggested length in these End to End directions always seem like they will most likely make for a very long endless loop iirc.
Now, if you want the tails to overlap each other because you are going shorter than whatever the End to End instructions calls for, you probably going to want to use the 12strand Eye to Eye instructions, just minus the eyes..
Now when i said i had not tapered enough, i don't mean i didn't do enough at the tail ends. What i mean is that i never removed the 6 strands that start a little past the brummels in the Eye to Eye instructions that make the overlapping tails alot more compact & able to fit within the 8in x-over. At the time i was unsure whether it was OK to do this in the loop configuration as the End to End instructions want 5 fids worth of tail without any mention of removal other than the very end. Which says to me you need allot for it to be secure. So ignoring those lengths while removal as well didn't seem right to me for the size i was trying to complete.
How was it popping out- It was popping out / herniating because of the fact the X-over was so full of Cordage & the fact that the T-Rex frays very easy & is really slick when new. The x-over was still bulging even after doing heavy tapering for the last 8inches that make up the X-over (4in earlier than eye to eye xover instructions). Because it was bulging, the strands were seperating enough that any of the dual carrier stands underneath inside the bury were easily able to pop out.. & when there's so many strands cut inside there (that's 2 per strand), it's not hard to end up with something that looks like the picture above.
This may or may not be the case with any other 12 strand dual carrier Cordage, but i think it was exaggerated by the fact that the T-rex is so slick & easy to fray.
I was able to undo the one in the picture & resplice it without losing length, i actually gained a few inches because your gaining cover length back by removing the strands as if it were a Eye to Eye process instead of End to End where no removal happens.
