Default brummel

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.

Default Great minds run in the same ruts

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

Default Many, many men with greater skills than I, and there is nothing new under the sun !

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.

Default lock-stitch

It is also entirely possible to neglect the brummel entirely and simply lock-stitch the splice. Lock stitching serves the same function as the brummel, and if done neatly, doesn't look horrible. I serviced over some of my lockstitched splices with St. Mary's hitching. Time consuming, but tidy, secure and handsome to look at.

Default Yes, but...

Hi again,
Stitching is tricky; I have heard (and will now need to dig up documentation) that stitching sufficient to provide Brummel-like initial security is likely to distort the rope, lowering ultimate strength. Be careful.
St. Mary's Hitching is indeed lovely, and if sufficiently drawn up would function much like the cover on double-braid, working better than stitches, without weakening the rope. Plain old service can work here, too.
Fair leads,
Brion Toss

Brion,

The recomendation is a pretty loose lock stitch (with three full stitches a side). I haven't destruction testing them, but I have made the first pass through the side of the bury at the eye, and going down two braids per stitch. So far I haven't had one start to pull, though I am just now starting to put them into regular service, so I will report back when I see any results.

Personally I just am not happy with my brummel splices since they always seem to be made too loose and start to separate pretty early on, though I have considered stitching them as well. It just seems a bit of over kill.
