Spectra lifeline confusion

[rockfordwoods]

Joe, I have read your explanation more than once, but obviously I will need to study it and see if I can do the same thing. I do not quite understand. Forgive my thick head. It is always a pleasure and informative to read one of your posts. Thanks for the information.

Dear Rockfordwoods,

Bugger!

Now I am going to have to delve into the alchemy of taking and posting digital images on this forum.

Do not hold your breath, but I will try my best.

I know it is not strictly kosher on this forum, but you could email me - joe@fpw.net.au - and we can discuss more fully

Joe.

Here is a video from New England Ropes of how to do a Brummel splice with one end only.

Anne, thanks for that link, but the issue here is how to use a locked Brummel to splice in a closed eyelet, such as a Johnson lifeline eye, without having access to both ends. I think it is not possible without passing the offending hardware through the rope. Joe has come up with something very interesting involving un-laying and reweaving the rope.

Rockforwoods,

Both the link I posted above, or the video akochen posted have instructions on how to do a locking brummel with only one end of the line available. It absolutely is possible, and a pretty easy splice really.

Hi,
And here I thought that I had come up with the unbraid/rebraid technique, after a friend told me it was impossible, some years ago. For those of you who aren't following Joe's description, you can find drawings of the process in our Working Rope 5 book, in the section on grommets.
Getting back to an earlier question, a Ring Hitch (I refuse to call it a Luggage Tag Hitch) does not have the kind of weakening effect of knots; the load distribution and balance is different. For lifelines, a Ring Hitch is important, as it allow one to attach and detach the eye. The Johnson hardware is proportioned to accommodate the hitch. Not clear on why one would need the unbraid/rebraid technique for lifelines.
Fair leads,
Brion Toss

Brion,

The more I think about it, the more certain I am that that I must have seen the essence of the Monkey Grip / Locked Brummell somewhere in the copy of Ashley that my mother bought me on the occasion of my entrance to the ranks of an indentured apprentice..

Without getting that bloody heavy thing down from the upper level of my bookshelf ( the only one it fits on, of course ) I reckon that here is something similar in the leather strap / thong department and I have seen it on the end of belts etc. so I have no great claim to it.

There again, as per the title, most of what we do has already been done, or at least thought about, either years ago or at the same time.

Vis the "invention" of the multihull and the development of the Windsurfer etc. etc.

There again I do love the syncronicity of it all, and the existence of the entry in your book saves me a lot of head scratching whilst I attempt to - 1) actually take the pictures, and 2) post them up on here.

By the way, I agree, luggage tag is just a lazy way of describing the hitch for uninformed users, and "great minds" can be set on their ways..

The correct nomenclature, and the correct tool, always.

Unless I really HAVE to use that Crescent wrench and cross head screwdriver as an adjustable hammer and pin punch --- quick !, while no-one is looking.

Regards,

Joe.

I think it sounds like you want to get a eye splice with only one end availble? If you are using 12 strand spectra you can always do a tucked splice vs buried or a mobius brummel but it would require a shackle. A tucked splice is just as strong as a buried one and can look quite nice if you take your time. There are instructions on several web sites.
