OK. I put a reversing switch on my rope walk so now I can mark them Z and S
Whenever I use single lines per hook ( for Z laid) then yes they have to be unwound then rewound which is why they grow then shrink. Stephens correct when you run more than one line per hook then that process can not happen. In either case for Z laid the gears need to run counterclockwise to make the threads spin clockwise thus producing right hand twist. All of my source threads are manufactured as right lay. Again I do not understand every thing I know about this but as long as the end product looks good it doesn't matter.Have you had any complications with having to twist it backwards. I noticed when I was twisting a single thread backwards that it got longer and then shortened up as you would expect.
With a single line on one hook I make it lefthanded. With serafil you need indian eyes to see the difference between left or right. What can be see is that when righthand twisted in that case the rope is not equal turned on the lenght. That's why I make an exception for that case. And it confused me indeed too. That's why I made notes on my ropewalk to don't forget or get it wrong.Whenever I use single lines per hook ( for Z laid) then yes they have to be unwound then rewound which is why they grow then shrink.

I like my serving tool reversable switch better because its variable control in either direction. I think that is called 'rheostat' or something like it.I used the elektronica left right unit of Aliexpress, I mentioned in the partslist of my serving tool. Same thing.
Don,My rope walk is made from an old sewing machine. Since it was an AC motor I was unsure about reversing the direction. I Googled "reversing a sewing machine motor" and found that sewing machine motors are AC/DC motors and they are reversible. You just have to reverse the wiring on either the commutator or the armature. So I wired the commutator out to a DPDT switch and now it goes both ways. I'll probably only use it for single thread per hook like Stephan but you never know. I guess I can use it for cable.
Thanks for all the help.
Oh, Daniel do you use Serafil 300 tex 10 for all your ropes? I can see that larger diameters would need LOTS of strands.
Good advise to talk only about S or Z laid. And yes hawser or cable are the same, a mistake often make.One of the major sources for misunderstanding in rope making imo is the wording
"Laid Right" and "Laid Left" is the most problematic way to say. What is meant? The resulting rope, or the direction the ropewalk is turning? From wich viewing angle? In front or back?
The best and safest way is to talk of Z- and S-Laid in combination with right handed or left handed as the thumb of the hand is showing the direction of the rope lays. Even hawser & cable laid leads to misunderstandings because Americans mixed it up around 1847.

Hawser, I got a problem with this English name, is rope made of 4 ropes? It's like Paul said. This is not my native language. And cable could be made out of 2 or more ropes. What is the difference.Ähh no Hawser and Cable are NOT the same ;-)
cheers

I really suggest reading my paper (link above) as it explains everything in words and pictures But I can explain here later too, short of time right now.Hawser, I got a problem with this English name, is rope made of 4 ropes?

Can you see any difference between Hawser and Cable other than the twist direction?

To me I can see a big difference between a standard S laid rope and a cable-laid rope. The 'strands' of a cable-laid rope are Z laid. Then take at least three of those Z laid ropes and twist 'them' into an S laid rope. As a side note early on when I started making rope, I made only S laid standard rope and found that using polyester source thread, the rope had an unnatural spotty sheen appearance to it which when compared to Z laid, looked awful. I've added some comparison photos you can see for yourself. Also in this example 3x3 meant 3 source threads (one per hook on machine end) and brought together at the weight at the bottom. All three threads could be spun as independent. Since each source thread had three yarn threads I thought the setup was a 3x3.Can you see any difference between Hawser and Cable other than the twist direction?
