Triple ring eye/ loop sling: Update - Half Brummel?

[shaddart]

Hi, I’m pretty much a beginner with splicing, but I watched this video, and I’d like to make the prussik style sling this guy uses.

He’s got the triple ring sling tight in a locked Brummel, but I can’t tell if the rest is an endless loop or one large eye. Also, I have no idea how to make it just the right length for the three chokes prussik style with no floppy leftovers, ie the triple ring flush to the double ring sling.

Here’s the video- Thanks!

I think it is an end to end splice to make a loop after using a locked brummel for the triple ring.
The buries expand and shorten the Tenex, you can determine how much before doing the splice. As an example, say each of the buries are 10”. Measure longer than the bury by 6” and make a mark, this would then be 16” from the entry point of the bury. Do the reduction on the tail and do the bury, and then remeasure from the entry point to what was the 16” mark to see how much you need to add for each bury.
The loop should be long enough so that the number of wraps is longer than the stiffness of the buries, which will form the bridge of the Prusik.

OK, I understand.

Would two 10 inch buries be long enough for 5/8” Tenex Tec?

Because it looks like that’s all I would have room for.

Also, do I need to lock stitch anything?

I think basically I’m trying to make something like this, but with a loop about 23 inches long not including the ring.

What do you all think about splicing the endless loop first, then sewing the eye around the triple ring like this:

?

The Brummell looks easy, and I think could be tightened better around the ring, I was just wondering if this is just as strong, since both legs are loaded equally.

Sorry if these questions are super basic, I haven’t done much splicing, as you can guess

Thanks in advance everybody.

Technically 5/8ths with 10” buried would be pushing it quite a bit.
A Fid is between 21-23 rope diameter for reference.
And yes if you have to ask lock stitch. Cheap insurance

For a straight bury it would require 2 fid lengths, Samson has video doing an end to end in 5/8“. The Tuck-Bury splice only needs one and a half fits. The stiffness of the buries would be better wrapped around the thimble, like the video you posted, then in the loop, like the X Ring loop.

Ok thanks, The 5/8 Tenex Tec barely fits in that triple ring, not sure how the thicker buried section would fit in there but maybe I’ll give it a try. Or maybe a chafe sleeve over the crossover point if I did it like the x-ring loop?

Thanks

Actually, I miscalculated, I would have room for two 21 inch buries which is about a fid and a half, But as Brocky pointed out , the buries would shorten my loop length so once I figure that out I’ll have extra length in the buries to end up with 21 inches lengthwise in the open, usable part of the loop.

Thanks!

Update: I did the double Brummel with a regular old end to end splice, but just for fun I pulled it out and passed one end through the other- kind of a half Brummel? Then buried each end. Is that legit? It seems less likely to creep out, but not as strong, but I have a locking brummel on the eye anyway.

Of course I would lockstitch it.

Any opinions?

Gonna try now with a double/locking brummel.

Ok - I ended up doing a “mobius” brummel like in this video-

it got a little sloppy because of twin strands of the tenex tec, Also I was using the same rope that I had already tapered, so i switched back and forth between 3 strand and 4 strand braiding to create the 4 strands needed for the final 4 strand rebraid on the inside of the loop. Also need to practice the beginning of the rebraid to make it tighter.

At some point I’ll redo it with a fresh piece and taper the ends after I bury them.

In case anyone is interested, I started with exactly a 10 foot piece of rope, and the buries ended up being about a fid and a half, including the tapers. You can see in the pictures where the mark twos ended up (2 fid lengths from ends) When I tried to bury there using a straight bury the crossover wasn’t centered in the loop for some reason, which actually might not be bad since that is the choke point of the loop. I marked where it looked like the center would be and used that for my cross over point. It looks to be about 10 pics from mark 2 which is just under half a fid.

I’m a beginner at this so any comments are welcome.

I like this mobius brummel because the only way for it to pull out is if the braids unravel.

I know it’s sloppy, I need to practice that first part of the rebraiding.

Using the rebraid method with a fid and a half bury on double eye hitch cords, I found there was a loss of 40% of the cords break strength. The Tuck-Bury splice only loses around 2% for an end to end pull on a double eye, a loop tested at 1 1/2 the cords strength.

Not a Mobius locked brummel, that involves inverting the tail twice, yours is a rebraided locked brummel.
