No Knot Loop

[opie]

Just for technicality's sake, the continuous loop connection is not a locked brummel, it only resembles one.
Not trying to be the grammar nazi, just figured I'd point that out.

Correct, Its not a true locked brummel. The only reason I pass the line through itself is so I can pull the tails tight prior to bury. It adds no integrity to the loop.

TeeDee does use an actual locked brummel on his.....

If youre making these from the smaller Zing It lines, I dont see the neccessity in worrying about the weight rating.

For the Amsteel Blue loops.... I tried pulling one apart and my biner gave out at 1600# while the loop was intact.

Or for maximum strength efficiency, avoid pass through altogether; simply bury and taper each end, and use a lock stitch.

Not too sure about that.

Brion Toss has tested and his recommendation is that the Locked Brummel followed by the bury doesn't lose any more strength than the simple bury alone.

Opie has converted me from the stitching to the locked Brummel - much easier and faster.

Very interesting TeeDee. If Brion says so that's enough for me.

I failed to find that reference; you have a link?

In any case, if I understand the method used for these loops, it introduces more distortion (hence the "bump") than a Brummel eye splice.

He sells his books on his site. One of the books deals with splicing the dyneema/spectra ropes and he advertises a bonus in the book of an eye splice that retains 100% of the rope strength. I could let the "secret" out of the bag (probably not ethical) or you could buy his book or you could email him and ask or you could guess based on the topic of discussion. Your call.

As for the distortion caused by the locked Brummel in a continuous loop? As Opie says, there is more of a "knob" than the plain bury that Opie uses, but to me it is hardly noticeable.

Here is a picture of the Locked Brummel continuous loop in both 3 mm and 1.75 mm Lash-It:

I didn't read Working Rope - Basic Braided Splices but his blurb says "this splice will approach 100% efficiency".

In any case, one manufacturer reported that breaking strength is tested with a Brummel eye on each end; obviously 100% efficient in that case (which I is suspect is common). Other methods of testing involve attaching each end by several turns over cylinders with a very large D:d ratio, &c.

I'm addressing strength efficiency (not cosmetics) and I imagine the fibres do notice.

Hmmmm. fwiw - I found this post ( #30 ) by Brion Toss, though here he is talking about 1/2 inch or larger lines, not the smaller stuff hammock folk use.

I must say I never heard of the word Brummel until a few weeks ago. In searching for explanations about them I came across forums discussing, Brummel, Locked Brummel, S- Brummel, MacDonald Brummel, Paraloc Brummel , Mobius Brummel, and other types. No wonder it gets confusing.

Thanks for that link (good summary)!

I suspect most of these names are essentially redundant while some refer to different methods of producing the same result (either a locked or unlocked Brummel), but I also find the subject confused (if not confusing).

I especially like this method of making a locked Brummel eye (though it appears the dimensions apply to nylon/polyester rather than HM cordage).
