Splicing high-tech double braid.

[jeffh]

Kristian is right about the Flight Line, but since the oversized cover is short lived polypro, it's just as effective to strip the cover and lock brummel and go core only, with this configuartion of line.

When inserting the core into itself this entry will be well inside the standing part of the cover, as the splice is drawn up. I've found that a small fid (or large sail needle) is helpful in holding the two marks together as your drawing up the splice. Be sure to massage the slack out of the eye as you're drawing up the splice.
You should have to snap against a belay until the very end with endura braid as its cover has some give.

In addition to Brion's Books (both the Apprentice and the field guide to braided rope splices) take a look at the English Braids website. They present some good photo sequences in their Splicing Directions. Their cordage is a bit more "Marlow Oriented" with the techniques differing somewhat however the principles are still the same. Their core to core splice does employ a cordage with an "intermediate cover" which you don't have to concern yourself with and they cheat a bit by lopping off a bit of the core which makes a little more room in their extra tight tweedy cover.
good luck

Just wanted to correct my ealier post, you SHOULD NOT have to snap against a belay too much until the very end of running home a covered Edurabraid eye splice. As with a normally constructed core dependent line (with an extra thick covered line like NE Ropes flight line you'd take the 48 diameter measurement only on the core-if your retaining the cover over the eye), the proportion of measurements offered by Brion's method allow adequate slack in the cover until the last inch or so of burying, when a little helpful snapping comes into play.

As I said earlier with endurabraid it (the cover) does have a rounded relatively "forgiving" nature and makes running this splice home pretty easy. V-100 and T-900 are two examples of core dependent lines, from NE Ropes, that require a little more coaxing to get home, as their covers seem to run a little tighter in their weave.
sorry if there was any confusion.

I think that the core offset you are thinking of is what gives the cover the slack to fit two cores inside the line, Kieth. maybe i misunderstand

!!! there should be no jerking or slamming of anything - not with splicing core to core and the covertail not buried inside the cover.

even then, or really with any splicing of new line commonly used on sailboat rigging, would I say that slamming or jerking is never needed or ever good- I can recall having to slam my way home when splicing- or even setting the line up between two points and dropping my weight on it to move thing along- thats how I was taught to treat line when things weren't going easy. Or I had learned anyway.

Now I have figured out that that is not the right way to splice. Being gentle is much better for the line and your body, and easier on the wrists, elbows and shoulders. Easy on the strands, the helix of the lay, and the splices ability to provide near breaking strength of the line in load. So take it easy - no jerking.

Especially not with core to core and no cover bury- on endura briad, that should be an easy slide.

When applying load to tenson the core and milking the cover down over the constricted core, use your body weight leaning back holding the core in one hand and milking the cover down over it with the other. If things really get stuck - then your trying too hard, try less cover at once, or sit down and 'massage' the line to help work slack into the cover strands from further down the cover . Once the cover is up and over the splice you might have some slack ( if you marked right you will not) and it might be ok to loosen the 'knot' you used to work off of, and milk the excess cover back and forth from the eye down the line and back up to the eye.

Be easy on that line- it would not take much abuse to have many strands bearing no load,due to deformation by rough handling. We see it all the time - bunches of core inside cover, loose cover, incorrect buries. Really funny is when you see those big snags or run showing that the tools use to splice had sharp edges or raised shap edeged lettering- or just that the line was really abused. We call those splices ' Frustrated Lumps'

Splicing is actually really easy to do - have a beer- and enjoy !

Hmmm.

Hadn't thought of that. Guess that makes sense, and since the difference only a few diameters, and there is a ton of extra bury.

I have a firm grasp on standard double braid splices (normal braided dacron), and only later got into locked brummels for single braid.

So this is just an evolution on my skills. Just trying to try it in my mind before I try it for real.

Thanks for all the input. I will be giving this a shot some time soon.
