Ok, I also found it surprising that that was their suggestion. But I guess it sells easier like that. I don't have a machine to sew it but can't be much of an issue doing it by hand. I'm not so convinced by this brummel splice on used lines. They're already slightly frayed, dividing them in the middle doesn't make things any better. Video's look OK because they always use much thicker lines for the sake of visibility but when I did one on a used kiteline, it didn't look very strong, probably on new lines things are better. So I'll sleeve and sew. Regarding the afterthought: no I was referring to a putting a sleeve, looping the sleeved end of the line and knot it off, leaving a sleeved loop with knot in a section of line that carries the full load. As basic as possible. Well, I'd have used an alternative knot probably.Herman wrote: ↑Mon Sep 23, 2019 6:32 pmPemba
The kitesurfing mantra I have lived by regarding flying line is that you generally lose ~20% of strength if you put a knot in a line, and the only kitesurfing flying line that it is acceptable to knot is Q power line. Q power line has a core and is not suitable for splicing.
It is often difficult to find hard and fast data but I think the above mantra is a good starting point. Although sleeving would increase knot radius and perhaps reduce strength loss I would never use knots to make loops in line that could be spliced. Also I would rather use a larks head to stopper knot than, a knotted loop, as the knot would not be in the fully loaded section of the line, (in say an old line that could not be spliced). Just my opinion of course!
Sleeving and stitching is also perfectly acceptable and is better than knotting!
Afterthought: or are you just referring to one end of the sleeve and burrying the other end with the tail, if you are, possible perhaps but not worth the fibre disruption imho.
That method is a throwback to toy kites and nylon kite lines. That was how it was done before the invention of dyneema and kitesurfing and real power kites.
If you're going to do a lot of splicing buy these. https://d-splicer.com/d-16-scissors-2/Foil wrote: ↑Mon Sep 23, 2019 8:13 pm....
the hardest part to get right was feeding the wire up the center of the tail for the bury part,
it takes a lot of practice to prevent the wire popping through the side,
thinning the tail end to avoid the bump was easy with a new blade in my modeling knife, scissors were rubbish at this, well mine were.
