Hah! I just made one of these suckers w/1.75mm Lash It...not something I want to do often, but it can be done.
Just found this link today:
It creates a single-ended locked Brummel, much as the McDonald. The difference, per the illustrations, is NOT having to push a full-size eye loop through the little 'football' opening.
I haven't tried it yet (will this evening), but I expect it to work better in smaller cord like Lash- / Zing-it.
Ignorance is temporary. Stupid is forever...
I'm not high maintenance! I'm simply low tolerance.
Yep, that's the same link as in the first post.
The trick to using the NE Ropes method is to use a small piece of whipping twine to pull the line back though itself. It's a little finnicky, but nothing that can't be done.
If you're making a sling with an eye on each end...
Another method that works great in 7/64" and 1/8" amsteel as well as vectran lines is to push the eye on the other end of the line through just as you would the tail. It hurts nothing to enlarge the opening a little and when splicing larger line, drastically opening the line is required.
but my question is WHY??
Locked Brummels are not required. You can use a straight bury or a regular brummel, both of which are stronger. Locked Brummels are WEAKER than the other splicing methods. Some may disagree on how much weaker, but no one with any experience will say they are as strong or stronger.
The reason for locking the brummel is to prevent the splice from working loose under low load conditions. The same thing can be done with a little whipping twine, sewing thread, or dental floss. Either stitch the bury for a couple passes or whip the beginning of the bury. Both methods keep the splice from working loose under low load.
