:thumb: That's a neat video!

You don't trim to taper but you mention it.
I do the trimming/tappering last thing before covering the core.

Looking forward to the next video of yours!

Wow Gunnar I was about to say excellent video!, but then you forgot to cut the taper into the tail :-/ I was like wow you're opening the weave which is not what I do but is the proper way to do it. I thought crap you're going to pull the tail after you cut it, that will be harder but no you did that good. But then no cutting at all. On thick ropes manufacturers actually recommend to measure out the strands to cut them for a perfect taper.

I see you got a fair bit of criticism on the first vid for the taper length or something ( not paying full attention lol). The brummel can actually handle quite a short tail when full strength is not needed. The main reason for the tail length is strength or to stop it slipping out. When ropes or thicker lines in kiting are used in pulley lines or bridles or pigtails or depower ropes etc this is not for the extra strength of the thickness but for durability and perhaps for pulley lines better fit on the pulleys. For these thick ropes knots or short splice which reduce strength dramatically but are perfectly fine. The problem with short splices is they slip. Enter in stitching which is another way to join things, stitching a splice will prevent it slipping and can make it strong, you can even stitch lines with no splice, see standard sleeved ends on most kite lines.

It would be great to see a video on stitching lines. Home machines are quite up to this task and can sew any ropes that will fit which is quite fat. The fibers in ropes especially UHWPE offer very little resistance to a needle.

It's not tapered. The brummel shown in the video somewhere around 50% a properly tapered splice and close to strength of a figure 8 knot.

Could anyone help how to create universal pigtails?

Issue is that kite and bar is opposite with loops and knots.
That can be solved with universal pigtails - https://www.youtube.com/watch?v=PmykTPj9uGs
But how do I create the know in one end?

Start with the end you want the knot on the loop, use the Brummell method for when you can use both ends...

Loop in both ends - how will that solve my issue?
I need a knot in one end - if I just make a not, will my line not be weaker?

Is it possible to do, without sleeve?

The thicker a line is, the less it weakens from a knot (makes sense since the folding is more gentle the thicker the line is.)

In general for the pigtails you will use much thicker dyneema than the actual flying line, therefore even if weeken they are stronger than the line.

If you want a pigtail with loop in one end and knot on the other, the simplest thing is to take a 3mm dyneema, fold it in half and make a figure 8 knot.
Ugly but it works.
If you bury and do a figure of 8, that would prevent slipping.

Make the loop a bit bigger and put a knot in the line exactly at the middle of where the loop will be BEFORE making the splice. Lots of knots will work you could use a stopper knot if you want it bigger, might be hard to brummel with a big knot though.

Cos it's a loop with a knot in the middle.

I thought that was what you were asking about.
