Made the lockline out of 2 x self-locking brummel, one for the safety, one for a loop.

That looks interesting!
What if you feed the safety line through both of theses loops? Or did I not get your idea right?

micro sleeve:
I came up with this, cause the safety line always sits rectangular on the locking line under load. For that, a both sided support of the lockline hole makes an ugly squeezing. I'll give this single support approach a try.

2nd side:
didnt know what to to with the seconed side. As I'm a fan making those things symmetrically my intent as to support both flying lines with identical locking line mechanics:
one side is used with the line going through, sleeved with the safety line.
Other side is just sleeved through that lilltle hole, connecting this way to the lockline itself.

First thought with this micro loop dedign, was to give the opportunity to make something like a oh shit handle with the second side. But I dont think I'll do this. But perhaps a short sleeve as blocker, too, to make service of the line possible from both sides.

How do I fix the lockline to the depower system?
The lockline itself will be interlocked with a selflock at the depower system, to prevent from slipping, when unloaded or in safety mode.
My experience says that, up to an opening angle of ca. 20° this little interlock is working pretty well (I make foil bridles this way).

As said, I will document this when ready with some fotos...

In rockclimbing dyneema sliding on dyneema is a no no , bc of melting the fabric. The intention to make the rig free of metal is good, but aren`t we talking about a tiny steel ring what is saved for this solution.

If I am not mistaken, in the flysurfer solution there is also dyneema slyding on dyneema. The only way to prevent this is a figure 8 ring, where the attachement is separated from the safety line. - Tom

Maybe we should start a separate topic about custom line organizers...

The small steel ring Flysurfer and sk shapes is using is still a point of wear on the power line itself, as will always be when you use steel rubbing against Dyneema combined with sand.

Hope you can see it better on the pictures below. You can also use it to compensate for a few centimeters of length difference in the power lines.
When it is not loaded the power line can pass freely without much friction when flagging out as there is really not a real force that pushes the power line against it other than the weight of the bar. But it is not designed for school who flagout multiple times a day.

In rock climbing I can understand their point as rubbing Dyneema against each other under load can melt them indeed. I see that every week with the bars I get for repair when two riders get a tangle and rubbing the lines against each other with force.

yes Evan.
Sorry for pirating this thread, it was just enthusiasm about yr idea. Made a thread in gear builders now.

Thank you for sharing yr genius ideas, they are an inspiration.

Anytime at BDam I would like to give Infexion a try for a foil setup I'm looking for.

For nixmatters and all who like to gearbuild something:

Evan - thanks a lot. Indeed, now I see how it works. Brilliant, can't believe that this is really reliable, but will test myself. - Tom

I did a crude dyneema on dyneema friction heat test. The result is detailed on the Mach Flott - bar ideas thread if anybody is interested.

Hi Evan, does it really need to be in one piece? If you splice the second interlocking loop, you are not able to make a brummel splice, right?

I would have created two separate lines with a brummel spliced loop on one end each. Thanks for your comment! - Tom

I have not much experience with brummels, normal splice is faster and stronger to make if you have a sewing machine at hand.
But is doesn't need to be a single piece, it just make the setup much cleaner and shorter.

See the pics of the mod on page 11
Warning, with this setup the leash anchor point can slide out, if the QR is pushed out beyond the normal release position.
What happened: I had to QR a bad behaving Sonic2. Instead of landing on a small beach, he flew into some trees . Because i pushed out the QR too hard the sleve of the leash anchor point slipped over the " leg of the claw". Positive: With the modification the QR works much cleaner.
Have to think about a better fixation of the leash anchor line. Any ideas?
Have to look now after the Spaghetti-Sonic. This suxxer is really trim sensitive.
Edit,Evans setup is safe if the loop line with the Ring has the right length, if too long it can slide out. The ring& knot stops the QR from disconnecting.
The Sonic is ok only some scratches
