New idea for repairing rope?

I see that in theory it would be easy to repair cut strands in a rope by inserting a new strand that sufficiently bypasses the compromised area in both directions. essentially splicing new strands.
What do you think?
Just an idea wondering if anyone has tried this?
 
Yeah for real!

You splice rope right?
Is it that far off to expect a technique tried and tested
would work for strands in a rope?

Over the years I ahve retired 100's of dollars worth of rope
because of cut strands and see this potentially being a good way to salvage a rope knicked by a spur or saw.

1 cut strand
2 tie off end to new strand
3 weave the new strand
4 tie off/stich or lock it off

What do you think?
 
I am not a splicer by any means, but I say No Friggin Way! You aren't patching a tire, it seams to me that the whole of the fibers are what make a rope a rope. A patch is just a patch and would have no strength.
Why not use Duct tape?
 
I leave my splicing to the pros as well.
seems to me if the strand is sufficiently inter woven its not a patch but a full repair.
Patching a tire is superficial this technique is an integration of a new strand into the rope.



Mb we are just resurrecting an old technique that may be applied to new ropes.

Hope rope manufacturer can add to this.
 
A long splice in 3 strand roe is really just that. I've never done one but from the directions I have read seem to be very similiar. I don't think I would trust my life to it though, maybe for tying down loads of brush etc.
 
RopeShield,

You 'know' the stock answer from any Rope Manufacturer would be to discard and replace. However, by the same token, I challenge any of them to claim that the integrity of the rope is compromised as a PPE just because one strand got cut on a 16 or 24 strand rope.

When you factor in the 5300# stupidity farmer built over built standard you can probably cut two or three strands and still pick up the family car and with the fattest tree worker ever to climb a tree in the drivers seat without a problem. Just never climb above your TIP though as that changes everything.
 
Taken from Yale Cordage
"Broken or cut strands reduce the ropes strength thoughout its length-not just in the area of damage. As a general rule, retire your 12 or 16 strand rope when more than 3 broken or cut strands are visible, or if two adjacent strannds are compromised"

Why not repair the cut strands and maintain a bit more strenght?

I don't know how easy thia would be, you would be essentially adding a strand into an already tightly woven rope. Plus, you would probably have some distortion in that area from that added strand. Not to mention the likelyhood of the strand picking.

It would maybe be possible (but not practical in my mind) to pull a whole new strand into the rope using the cut one. It would be alot of work though!!!
 
What if you:

1) Pull out the strand far enough back in the rope to be able to tie it off with a DF knot
2) Join to a new piece of thread or whipping twine.
3) Pull the DF into the core with a wire fid
4) Finish this off with some whipping stitches.
5) Do the same thing at both ends

Any reason why this would not be a sound solution to 'save' an otherwise good rope ?
 
Cheap is relative and not the point.
Still hate that word. Its not cheap its a nonrenewable resource.

Just Looking at alternatives, options and viable solutions and it may be a goose choice but the point is to keep learning and in the vain of reduce, reuse and recycle. and repair!
 
I like the idea... But what exactly are we talking about... What kind of rope? If the manufacture says the rope is still good with 2-3 strands cut, is it worth it to replace a section of the strand? Would a hitch still run well? If it's a double braid I'd say no way (can't see core damage). Wesspur sells left over short lengths, start experimenting and have them broken. If you don't have it get ashleys book of knots, if there is nothing specific (which I don't think there is other than the 3 strand long splice) it will give you some ideas.

Long ago before I knew much about splicing, I repaired a crab pot with that cheap yellow plastic hollow braid. I formed my eyes, raveled the tails, and wove them back into the line. It was a non critical application. Time consuming but worked great! If I were to do it now I would just do a long straight bury...
 
Just the principles like 24 16 and 2xbraid rig rope.
there might be someone out there reading this thread looking to keep busy and wants to extend the life of a rope with maintaining a high level of safety.

The new rope technology from Teufelberger is based on this principle. That would be the seed for this idea.
Titanium?
