Feeling uneasy about amsteel

[jakhammer]

how did you attach your second bridge. I feel like I did mine correctly I just want to be sure. I have a tether line that came with my cruzr saddle, it’s HTP line. So the sewn eye I girthed around left hand loop and prusik and stopper knotted the other side (carabiner locks right loop to prussik) . I’m assuming this is sufficient, I just want to hear some other input

you can also skip the biner and make a continuous loop around your 2nd bridge loop and make it into a prusik around your bridge rope. The advantage to this is less hardware to make noise and less weight. The disadvantage is that you have to "step into" your saddle instead of just wrapping it around your waist.

Been using rope bridges for years and now I climb off a central attachment (Petzl Ring Open) or a Delta link. Amsteel is pretty incredible but I am not quite convinced that it being used as a bridge material is the best idea. Just because a certain material is rated for a certain breaking strength how it reacts to a dynamic force is another matter.

If I could get some pictures tha would be awesome!

There are several threads here where people replica this using Oplux and TRC. You have to use knots in place of splices though. There are several methods, but a common one is:

1. tie a figure 8 on a bight on the end of a length of Oplux. Girth hitch 3 times around the bridge loop (usually right loop if a rightie) to make a prusik
2. use a length of TRC to make a prusik around the left bridge loop and also the Oplux and then use double fisherman's knots to close the loop of TRC. (I use triple fisherman's knots but it makes it a bit chunkier)
4. Tie your Oplux back into your bridge below the TRC so that you can't slide off it, leave enough slack for adjustment.

I do all of this using follow through techniques so that I don't waste rope, but that is more difficult.

Leave plenty of tag ends, finish your rope with shrink tube and super glue (both those ropes have non-melting sheaths). Everything will settle and lengthen. Do not finish it until you've sat in it with full weight and everything is settle how you'd like it. Buy more than enough rope and don't be cheap with it. You can work knots free and move them with the end of an aluminum knitting needle sold at Walmart (get purple, it makes a good splicing fid and you'll want one eventually).

If you haven't heard of all those knots and almost instantly know how to do this, then be aware of that. Watch online tutorials and practice these knots over and over. Making your own gear is potentially dangerous and you assume all liability in doing so. If you are not handy and willing to spend hours and hours to learn this, then you are safer to stick with your amsteel bridge for now or explore other options (like webbing).

Hanging in your new creation at ground level first and inspect it over and over before going to height.

I concur with Raisins assessment that anyone contemplating accessing trees using ropes should educate themselves in tying knots, hitches, bends and then practice until you can do them naturally. Remember to tie,dress and set all hitches etc. If a person can take a recreational tree climbing class it will greatly benefit you.

Thanks! I appreciate the feedback, I’m normally a strong DIY’er and extremely competent (I know your not saying I’m not) and it’s understandable to leave that disclaimer . Sometimes the shorthand names of things trip me up and once I see a video of someone doing it I’m like oh... well that makes a ton of sense. I feel more comfortable assuming my own liability because I know how I did it. But I appreciate everything you guys are doing for me. I’m contemplating on oplux but what made me nervous was hearing the dangers of small falls with oplux not being able to handle it. Which is why I stuck with HTP for my tether.

Well the post is about amsteel, - the utuilibrdge in the video could be made with any hollow braided rope.

Don't have to step into your saddle. Put it on over your head.

You know what, I've always instinctively stepped in and never thought of this. Haha...thanks for the light bulb moment.

It reminds of this year driving and I realized that a hairpin turn is called that because of the tight curve on the back of a hairpin. Only took 28 years of driving to figure that one out.
