Full Suspension Hanging setup

[xjxj]

Hello people of Sasu,
I've made a possible hanging setup with 12mm polyester (static) climbing rope over my door, anchored on my doorknob.
I would like some suggestions or comments on this setup, as I do not want to fail my attempt.

Here are some pics:




The knot is an arbor knot, and the anchor knot is a bowline knot.

I'm a little bit concerned because my rope seems to have trouble tightening to its fullest when I tie the knots. (you can see it in the bowline knot and the stopper knot on the arbor, there is a bit of gap that have trouble tightening.) Is this bad for full suspension hanging? I think this is caused by the thickness of the rope (?) How should I make it more flexible?
Note: I bought this rope a week ago, so it's fairly new, if it matters.

Looking forward for any suggestions.

About the rope..

That type of rope (Kernmantle) is somewhat difficult to tighten the knots because it has an inner core of fibers. That makes it more rigid.

Perhaps you could test the ligature on one leg and pull on the free end to see if it tightens and penetrates well. Or perhaps you could get a braided rope without an inner core, which are more flexible.

You can put adhesive tape (or burn) to the ends of the rope to prevent fraying, and tie a stopper knot (overhand knot) to the free end of the bowline knot for more security.

The knot at the free end of the arbor knot should be closer to the eyelet of the ligature.

thanks for ur info. Does my setup still work though? do I have a good chance of succeeding with it?

i would just have some method of being sure the rope won't slide to the side

Do you mean the rope might slide off the top of the door? If so, I think I will hot glue something, maybe like a small cardboard box, next to the rope so it doesn't slide off.

Were you able to test the rope? My concern with the setup is that the rope seems to be too stiff. Remember that the ligature (with the Arbor Knot) must be able to close completely to exert good pressure.

Can you close the door or will you leave it slightly open like in the photo? You can test the strength of the doorknob by leaving the bowline knot tied and take the rope on the other side of the door with your hands and apply all your weight.

If you cannot close the door, the rope will be too close to the edge of the door and might move due to involuntary spasms/convulsions after losing consciousness.

Perhaps you could consider this alternative, in case you can't close the door and lock the rope in a position more towards the center of the door and not so close to the edge:

Variant option, door + dumbbell or anchor object

I'm not an expert - and learning myself but when I looked at this method I wanted to ensure the door would shut and lock as I didn't want to slip off. I was also concerned that the door knob itself might not be strong enough.

Do you intend to shut the door? What is the height of your door. When I measured my doors I was also worried that if the rope stretched too far I would hit the ground (but im obsessed with height and hitting the ground so your set up might be ok).

The door should ideally be closed and locked shut, because it's stronger that way. But I doubt you can do that with that rope. If you can't close it, test it well before whether it's strong enough and able to hold your weight. You can make it stronger by wedging something beneath it, e.g. a door wedge. You can do one from both sides, which will also prevent the door from moving.

As @JesiBel said, you could burn the end of the rope to prevent fraying.

Also, tie the stopper knot as close to the main knot as you can.

Ideally, the knots should be tightened well, but if rope stiffness prevents you from doing that, that's not necessarily a problem. Just beware that some height might be lost as the knots tighten under load, and you need to take that into account when planning the height of the setup. Otherwise, these knots are still secure even if you can't pull them perfectly tight. Just tighten them as much as you can!

The rope can slide off at the edge of the door. I'm not sure whether using hot glue is safe and strong enough. You could also use another rope to secure your main rope and prevent it from sliding off (see image on the right). This 'secondary' rope doesn't have to be as strong as your main rope.

You could also use a setup like this (see image on the right). (Original post here.) It doesn't have to be a dumbbell at the bottom. It just has to be an object that can't fit through the gap. It can be anything, even a rolled up towel.

I was able to test my rope and the knot does tighten itself.
I will have to leave the door slightly open. Do you think hot glue-ing an object, like a piece of metal or plastic, next to the rope on top of the door will stop it from slipping off the edge?

Thanks for your reply

Edit: I think I'll go with the second rope to secure my main rope technique, although I don't have much information on how I would do it..

 

[Eriktf]

looks good too me just do a test first so you know it will work before committing to it, also you probably need more rope to loop going around your head need more rope but that can be adjusted in the test run, good luck hope you find peace if you end up doing it.

I don't think gluing the rope will work. I'm not sure about gluing an object either. Maybe you could try gluing an object and then trying to peel it off; if it's easy to remove, then it's not a good idea.

I like the ideas of AreWeWinning.

(another possible solution) You can screw on a metal L-shaped bracket onto the top of the door to act as a stopper so the rope doesn't move towards the edge.

Spoiler

You can block the door with some heavy furniture.. Something that won't get in your way and will keep the door as closed as possible.

I think the second alternative that AreWeWinning and I recommended is less problematic.
