Does anyone have a resource on undoing a splice? I've done some googling and haven't seen anywhere explaining removing one.
Cut the whipping twine carefully to avoid damage to the rope fibers. Pull any twine which pierces the rope.
Next anchor the rope a few feet from the splice, just so you can pull with two hands.
Where the end of the rope enters the host line, carefully pull while wiggling and pushing. With a softer braid it should start sliding out. You will see where the cover enters the core. This is called the cross over. As you pull the cover out of the core, you should see where individual strands have been cut to create a taper.
Next you will see where the core enters the cover going in the opposed direction. Pull the core out of the cover at this point. With a long eye, such as what you have, the core runs opposite in the cover through the length of the eye. From there it's buried back in to the standing part of the line for about 3". You should see where the core has been trimmed to make a taper as well.
You then should have two tails, ending in tapered ends. Take a long piece of wire (metal coat hangers work great), Double it over in the middle to make a snare. Next poke the doubled over end into the center hollow part of the cover near the first cut strand. Insert the wire up the hollow cover to where the core exits the rope. (you might need to take a few passes to get to this point.)
Next take the tapered tail of the core, and insert into the snare of the wire (FID). A little tape can help, but too much will make things harder. Next pull on the two ends of the wire together to pull the core back into the rope. Wiggle and massage the core and cover back into place..
Last push and pull on the cover to get both cover and core to equalize. Rolling your hands as if making a play dough worm helps get the fibers back into place. Now you need to trim the tail back to the point where the core taper is.
Watch a few you tube videos on double braid splices, essentially you are doing it in reverse.
My guess is that it will buy you about 24" of useable line
Brocky was typing faster. Certainly not unsafe if done right and well.
