Today I was making very thin thread from Guterman Skala; I used Skala 360 to make 0.2 mm thread.
Skala 360 is as thin as a strand of hair
I discovered that when you make a 3x1 (or 2x1 / 4x1) thread from Skala, the same problem occurs as when using Amann’s Serafil 120/2. When you use a single thread in a strand, you can only make left-twisted rope. This is because you twist the rope against its natural twist when making right-twisted rope. There is a higher risk of breakage during twisting or irregularities. Like this:
But if you turn it in LH the result is a perfect 0,2 mm rope.

I used 40 grams of weight, 8% and not 10% before I started the turning of the rope. Both machines in same speed.

Mmmm I can't confirm this Steph, I have no problems doing 3x1 Skala 360 RH rope ... I would try much more weight! I have 1 kg to tow.
I thought Skala 360 was a monofilament? I would have guessed direction wouldn't matter - but of course I am no scholar here...

When I pull on the sled, there’s already some resistance from its own weight. But 1 kilogram of pulling force??? I’ve never needed that much. The most I’ve ever needed was just 600 grams with a 2.5 mm rope.
I’ve mentioned before that not every rope walk is the same. Many factors come into play, such as the type of rope used to suspend the weight, whether you use pulleys or hooks, whether the carriage has wheels or slides across a surface, the weight of the carriage, the divider, and how much resistance it offers. These factors determine the weight.
That’s what I thought too; I noticed it right away while spinning—the carriage can’t move backward, only forward. It just sat there, and the threads started to sag. It took a while before the carriage started moving.
When turning to the left, the carriage started moving right away. So when turning to the right, you first untwist the yarn and getting longer; this weakens the yarn, and because the tension is lost, the end result is poorer.
I then took a closer look to see if there was a twist in the yarn, and sure enough, there is. It’s hard to see, and actually I’d need a microscope. Sofar I could see the yarn looks like a ribbon, like an old VHS tape for example, which has been twisted into a round yarn.
