Question RE Making your own rigging rope

[AllanKP69]

Hi Allan, my question is the actual measurements with period tables how come they are not mentioned? Frank

I am not at all sure what you mean (I know it is a translation issue ) Can you post an example of what kind of table you are describing?
Thanks
Allan

I think Frank wants to know how you get those thicknesses of your individual ropes. There are a lot to find about ropes thicknesses on ships. Like Steel, Yk, Witsen, Mondfeldt, etc. They all explain it different, but in the end they got the "same" thickness on each rope. And then recalculate that to your scale.

When you make rope from yarn for your model ship there are a lot of differences in the outcome.
When I make rope from example lock yarn Amann Serafil 120/2 and I make a 3 stranded rope of 2 yarns a strand. I get a thickness of 0,4 mm. in diameter.
But when make more turns in the rope with more weight on my rope and slowing down the splitter of the strands, I get thinner rope. So it all depends on your way of rope making and your machine you use. So you start to make rope on your machine and you adjust your speed and weight, that will bring out a result that will not be the same like I do. But my table that I made is just an indication for you. You have to make your own table of rope constructions.
You need:
The speed of turning the strands
The speed of turning the rope (these 2 are likely the same for the best result)
The speed you let turn the rope together (the speed the splitter is moving to the other side)
The weight or force on your strands
The length of your ropewalk
The kind of yarn you use.

Hello, these types of dimensional tebelles of the various monovre that I meant. Frank

I am making my own ropes and cables for USF Constitution. The final diameter of the model rope varies with thread size, thread batch even in the same brand, total number of threads in the rope, and the number of strands in the rope. 4 threads per strand with 3 strands does not yield the same diameter as 3 threads per strand with 4 strands. And the final model rope diameter also varies with the weight which you hang off the end, and if you harden the rope with a vigorous stretch (recommended), a strong stretch will reduce the final diameter compared with a lighter stretch.
So, the final answer is to experiment with all variables, keeping a record of the variables, so you have a reasonable chance of reproducing a previous diameter by repeating the previous numbers. I wind my model ropes onto used lavatory paper cardboard rolls and write the variables onto the roll.
The published charts give a ball park figure for model rope diameters, and are useful, but your own results are the best predictors.

I bought the Syren Rope Rocket a few months back. They have some information in the assembly instructions regarding sizeshttps://syrenshipmodelcompany.com/resources/ropewalkinsversion2.pdf)
What worked for me was buying a lot of thread and just making lots of rope. I buy Gutterman poly and over time have found I can produce pretty much whatever I want if I keep a supply of mara 120, 100, 70, 50 and 30. Five mara sizes gets me 10 rope sizes (1 strand or 3 strand runs. I have not tried the 4 strand option on the Rope Rocket yet) So now I have my own chart just complied by experience.

There are a number of videos on using the Rope Rocket on Youtube as well as a lot of info on the Model Ship World forum about fabricating ropes.
