Portable climbing rope rig

Anyone have a set up for a portable climbing rope rig? I have 30 meters on order right now (that was the shortest amount i could buy, but it was dirt cheap...) and want to bring it along with my rings, what kind of hardware would that require? I've seen set ups in gymnastics places that have a metal attachment to the end of the rope but I don't know what it's called. I've also seen nylon webbing attachments for aerial silks but I'm not sure that would work with a single strand of rope.

If you're going to make one of those you would cut an 8-10" section of 2" thick pipe in half, chop off maybe 1cm from each half on one of the long sides, drill two holes in each one at roughly the same heights, and bolt them onto your rope. Then (or beforehand) you weld a thick metal strap in an arc from one piece to the other to serve as your contact point! Once that thing's torqued down on the rope it ain't going anywhere. Just sand all your edges to be safe!

Obviously you should use threadlock on the nuts and bolts. That metal epoxy stuff works great too once things are torqued down, as does a spot weld.

I say just throw the rope over the beam ceiling beam or whatever so that it's right on the middle of the rope, hanging down with equal lengths on both sides. Then when you climb it just grab onto both in your grip. As long as you pull with each hand equally, it won't move :)

oh shoot. well i was looking for 3 inch thick, the shop owner said he had two inch but apparently he meant phase 2 knit and 1 inch diameter. hopefully if i dig deep into my inner 7 year old girl creativity I can figure out a way to braid this into a proper rope.

HAHAHA!!! Nice... If that fails you can always ask an actual 7 year old girl! Or... one of the local sailors, I would expect at least some of them can make rope.

LOVE it, Rub!

I was going to go about a different route to make the same thing, but I like what you did. I may try it. I suppose that for completeness I'll take a picture of what I made my friend and myself and show that here soon.

I did the same as rub but using a small length of nylon strap. If you go this route it's important to melt the ends so that if forms a nice thick ridge that the bottom clamp can hold.

However i will say that i have low ceilings and the rope is only a few meters long, i'm not sure how much i would trust this for a full length rope, and then would recommend something with bolts that pass through the rope.

It's beautiful. Video to come soon.

Used the 8 strand method (well technically 4 strands folded in half) and I'm using 2 nylon webbing lashes with buckles rated at 300kg each to rig it...overkill? Actually don't know the rating on the rope though so hopeeeeefully this thing doesn't give out on me. Anyways, measured the circumference, it's on average about 12 inches (more like 11 when you squeeze the crap out of it since my inner child doesn't braid that well). Based on the circumference, where I'll subtract a generous inch when gripped, the diameter works out to about 3.5 inches.

Sadly, there is no more daylight today so I'll wait till tomorrow to test this out.

That looks AWESOME! 3.5" diameter is crazy though, that's some serious gorilla grip you've got!

I bet that rope feels a lot better though, I'm going to try this as well. If you used 1" manilla for the rope you don't need to worry, even a single 1" strand has a breaking strength of 8100 lbs, so a safe working load of at least 1 ton.

To make you feel better, 1/4" manilla can handle 500 lbs and 1/2" is 2000 lbs breaking strength, so you don't need to worry about the rope, and it seems like your anchors are more than sufficient as well!

Gorilla grip is the goal, tried cirques on it the other day, could barely get a 1 second eccentric. Once I have a few months of 5 second eccentrics under my belt I think I'll unbraid and add two more strands and see just how far I can take this.
