double braid to 12 strand "Tail Splice"

[Brion Toss]

Hello,
This is one of our favorite things to do, not the least because, as you say, it makes for better use of materials. I hope to be providing details of some of these splices in a book and/or video in the foreseeable future. Meanwhile, it is first of all vital that you do actual destruction tests, not approximations with a chain hoist, so that you will know your tolerances. We have tested some of our splices at right about 100% of the HM line's strength, so I know it can be done. We have Brummeled the two cores together for some applications, simply buried it a long way for others. For halyards, one key is that the splice should usually be well past the winch and stopper before any significant load comes on. That way you don't have to recruit the total strength of the fatter rope, just the core. If you want to recruit some or all of the cover strength, you will need a long bury of the HM, plus stitching. This seems to work better than a long bury of cover inside the HM.
When you do bury the cover end, put the whole thing in, tapered, usually for a foot or so. Stitch so that it can't fall out; there won't be any load on it.
Fair leads,

New to this forum and just noticed that the post above is a couple of years old. Did you write the book on this splice yet? Any update on how to splice, say, amsteel blue to LS for a haylard?

Hello,
I have made some progress in writing; Book 1, Basic Knots, is only waiting for a few illustrations to be done, and we'll print it. Trouble is, the illustrator is in Kansas until March. Sorry for the delay.
Meanwhile, an uncovered single-braid to a conventional double-braid might look like this:
proportion the single-braid such that it is long enough to be past the winch before full hoist; proportion the double-braid cover such that it will be above the stopper by a couple of feet at full hoist; splice the single-braid to the core of the double braid; retract the core, pulling the single-braid in after it; cut off the excess core. The splice of braid to core will vary with the application. If constant diameter is an issue it is toughest, and toughest to describe. I'm not trying to avoid divulging here, but I wish the illustrator weren't in Kansas. Ashley shows a "long short splice", and you can do something similar with braid. If a little bulge will pass the stopper, then you can do a basic or a locked end-to-end. Some people just cut the two on an angle, and stitch the two parts together.
Fair leads,
