Have you done, or seen any data on breaking strength when you knot Q-powerline?
the makers of Q powerline recommend just loop ends simple knot to finish, and there you have it, full breaking load to spec or much more, the only test i gave mine was many years of use back in the early 2000s along with many others using overpowered C kites, never did I hear of any line failures, ever!Matteo V wrote: ↑Sun Jan 13, 2019 3:03 amHave you done, or seen any data on breaking strength when you knot Q-powerline?
I have heard of some test results from a trusted source that are a bit scary. That is why I sewed my Q-powerline sets. Still, I had issues. If you do sew loops, make sure the line is saturated with water during the sewing process and go slow. You can cut Dyneema/Spectra with the friction heat of sewing with nylon line fast.
Also, when making a line end termination (not a pigtail), Make absolutely sure the figure-8 knot is perfect and equally tight along all loops in the knot. An imperfect figure-8 is guaranteed to be less breaking strength than a perfect one.
Just to confirm my findings from over 15 years ago I have just been into may garage to repeat the "SNATCH" test.foam-n-fibre wrote: ↑Sun Jan 13, 2019 12:34 pmI've seen Q-lines break at the knot if a careless figure-8 knot is used where the parallel lines are allowed to cross inside the knot. If you take the time to get the half twist out of the figure-8 knot which normally gets created when you fold the line in half and tie the knot then I think the knot is much stronger, and I've never seen or heard of one like that failing.
