About rope thickness and padding

[Akashaaa]

I found the hanging resources posted here to be very helpful, but I can't find any concrete info about how thick the rope has to be, and more importantly, if padding is required/recommended?

My previous attempt with an extension cable and partial hanging (quite stupid and impulsive of me) led to terrible rope burn and brainfog that persisted for a day. I don't think I got lasting brain damage from that, but I don't want to take any risks going foward. I plan to CTB with a proper rope and through full suspension this time. Do help me out!

finger size or smaller iirc

I might as well post two relevant questions here too if someone reads them:
Is 10mm enough and would wearing a scarf work as padding?

Thickness of 10mm-12mm or 1/2 inch is recommended. Thick enough to really constrict around your neck, but not thin enough to bite into your skin.

As far as padding, it depends on the person. I use a folded washcloth for padding but others might not need it.

I've read elsewhere here (look for Evelyn's helpful posts) that a 12mm thickness is desired. I think polypropylene or polyester were good materials.

I have yet to buy my rope and practice my knots but I started my research!

Thank you! I placed an order for a 12 inch polyester.

I am still a bit unsure about padding because I feel that it would impede constriction due to the added resistance. I am probably being paranoid as the full weight of my body should tighten it regardless.

I tried partial and was able to pass out with the padding. I think it just depends on what you use. It did take me several tries a and some readjusting to get it right, though.

The rope thickness that is neccesary to block your carotides completly depends primaliry on the rope force wich is proportional to your body weight if you hang full. Rope force divided by rope thickness gives a limit value. If you underscore this limit you might have problems to pass out and if you exceed it you will feel unnecessary pain. For me 90 kg a rope of 20 mm thickness leads reliable to unconsciuosness within 5 to 15 seconds when I hang full. Of course the anatomy of your neck has an influence too.

Padding is counterproductive.

Not an expert on this an extra tip I have heard of you put 2 rolled up socks on the carotids, that will help put extra pressure on those areas.

The pressure needed to compress the carotids seems to be 7-8kgs, and assuming that the contact area is the diameter of the rope (12mm) and ignoring friction, I am looking at 52kg per cm which is way more than what is needed... I guess that I will have to order another rope.

Ps: Ty for the detailied response! It'd help if you can describe your experience with 20mm in detail.

Why is 7 to 8 kg the weight (it is not a pressure) needed to compress the carotids?

According to my experience a rope of 12 mm fits to a body weight of 54 kg.

I used a not constricting noose and positioned the knot between eye and ear. This is not the optimum set up to pass out quick, but I did a number of times.
