You want to keep your mind and sanity check out the following site How to Eye Splice double braid rope
very easy to follow and great results. I have no connection with the site other than have used for my own splicing needs and have been very [leased with the out comes.
It might be easy but it is not the way professionals do it, not the way the rope manufacturers do it.
So if the pros all do it a different way and this one guy does it a unique easy way it makes one wonder why?
Has anyone done strength tests and all the other tests that would be appropriate.
Did I read him right where he says to cut the cover off after pulling out the core?
