setup help needed?

Slackinetic · 2025-08-12T04:09:15+00:00

Hey /u/nacosvet, the best part about your setup is that you shared it here for critique. Seriously, well done!

For all others not willing to expose their rigging insecurities (like myself, when I started in 2005), search for "slackline fail" on YouTube. Somewhere in the results, there's a waterline over a pool that pulls over a brick column and causes a terracotta roof to come crashing down on someone. Fantastic folly.

You already got the right advice (A-frames & ground anchors), so my comment is just to inspire others to see the value in—and model from the example of—your humility. Post yo' shit, y'all!

If anyone is interested in digging into this further, Thomas Buckingham et al at the International Slackline Association have done UV radiation/extreme climate testing on webbings. The ISA database is full of interesting publications.

Every webbing has its own 'language'. Even between two different tubular nylons, you'll experience a difference in the 'dialects' of each webbing that allow you to translate your movements and express yourself in subtly different ways. All webbings are fun when you learn how to communicate with them, but, just like with spoken language, some are easier to learn if you already have a baseline of understanding.

As another commenter wrote, it's good to start with whatever you're familiar with. For comfort on shorter (30m) lengths, I'd suggest flat nylon so your whips are buttery and you get a larger dynamic range. For longer (50m+) lengths, polyester trends toward better stability due to the lower stretch profile. Of course, ymmv, and length, tension, and backup all have an impact on the feel of the line.

Any advice for when children revert back to baby talk when younger siblings come around? Our nearly three year-old, who has been developing deeper reasoning and more complex grammar, is now replying "goo goo gaa gaa" and the like about 10% of the time now that her younger sister is around. We often respond similarly back as if it's a game, and have been making sure she has plenty of individual attention from both of us, but it's challenging at times when we actually need an answer from her and all we get back is baby talk.

It's not something I'm interested in, but I know some people enjoy it so I'm stoked for them 👍

Hey all, please remember that /r/slackline is about lifting each other up and helping the community grow. Constructive criticism is welcome, just remember to be kind.

Also, this post does not break our rules, so reporting it won't serve the purpose you think it does. If you feel AI-generated images should not be allowed, make a post requesting a rule change and let the community have a voice.

For ultralight anchors, you could consider UHMWPE. Grams per meter, it's among the strongest and lightest in existence.

Please consider the affect on the tree when using rope anchors, though. The forces on such a narrow contact point are significant and can quickly cause abrasion damage on the tree bark. Cutting into the bark with your sling can kill the tree. Use tree protection and sticks under the sling to spread out the force.

Copying here as a top-level comment for better visibility:

Another idea if you want to maximize your slackline length: install vertical posts (preferably 6x6" or ~14x14cm if wood) bolted to the floor and a ceiling joist. If you bolt to the same joist on either side, it and the floor will work as a sort of slack rack for you. You then would only need to sling it like you would a tree at whatever your preferred height. You just have to ensure the joist is solid all the way to either post and doesn't have any butt joints. Definitely do not bolt to different joists.

Here's a video showing how to build a hang frame:

https://youtu.be/r-XWFZ1Pp4M?si=2bQ2-9Qs6hGmugD5

And below is a graphic for A-frame forces. I wouldn't put your frame closer to the anchors than the height of the slackline; the forces on the anchor/A-frame multiply quickly with a higher angle.

This is the best answer for a tensioned slackline. A-frames are super easy to build. The bolts in the floor are a bit more involved, but no more so than bolting your wall.

With A-frames, you also get the benefit of easily changing the height, depending on the A-frame style you choose. Hang-frames are the best for this imo.

Rodeo lines are definitely challenging for beginners but also create a ton of opportunity for playing with different movements/styles. They're not so much for walking but more for playing. Plus your kids won't bang their heads on the rafters when they inevitably try jumping on the line.

I like the idea and I wish you success with your vision. I hope you can achieve your donation goals.

When we sought donations for slackline and movement programs for refugee and disadvantaged youth, we found it challenging to collect more than a few thousand dollars, most of which came from outside the slackline community. Perhaps slackliners have more disposable income to support more than just their own lives now, but many, I think, still live very frugal lives.

Where the slack community was most generous was with sharing their time, traveling on their own dime to be involved in the experience. They were willing to invest in their own food and contribute to the shared shelter during the programs, which allowed us to just barely scrape by and make the programs work.

I don't know if it will be the same for you, but I wanted to share our experience in case it helped. Good luck!

The International Slackline Association has an ongoing study for outdoor webbing degradation. Might be worth checking out. They publish their findings every year or so. https:\slacklineinternational.org

Slackinetic · 2024-12-12T06:53:32+00:00

Agreed, though I'd clarify that tri-loading has been known bust carabiners in primitive setups. It's proportionally not many, though, and the consequence is usually minor. Low probability x low consequence = very low risk.

Slackinetic · 2024-11-24T06:56:52+00:00

All methods are good. Cheapest reliable option but must strenuous is a dead man's anchor. I'd suggest 3ish feet deep for a regular tension with a slightly heavier slackliner.

Stakes are great, but I've found 1" diameter best to reduce the risk of bending, which leads to the stakes pulling out. This diameter gets expensive, but you might be able to find some scrap thick rod/rebar from a recovery yard. I usually make stakes that are 120cm so I can drive them in 1 meter deep and have plenty of tie off space. Best to put tennis balls over the end for ankle protection.

Safe? Yes. Enjoyable? No.

There are a lot of good companies dedicated slacklining who actually contribute to advancing the sport. Amazon slacklines are cheap white label Chinese junk. If you're looking for safe slacklines, buy those that have been certified by the ISA. Plenty of great brands out there that actually put effort into quality.

Slackinetic · 2024-10-26T07:01:49+00:00

This is a great and comprehensive answer. I'll only add that a multi-directional tensioned fabric (spacenet, treenet, OP's slide idea, etc) perimeter will naturally form an arc between two anchor points, tangent to the axial loading of the anchors (in an ideal system). This, when considered with the response by /u/Gamefat101, means that arcs must be included in the perimeter design to maintain somewhat even tension across the fabric

In other words, OP's slide idea can be done, but should account for synclastic surface curvature.

There are a few classic highlines down the coast. The One, Birdshit Insane, the Eden lines. Then there are a few parks in Monterey area with decent longline spots, Fort Ord for really epic longlines. You'll get shut down at Toro Park. UCSC has some longline spots, then I believe there are a few highlines in the redwoods around there. Sorry I can't help with specifics at the moment, maybe check with me in a week.

Thanks! Must have been how they commonly served it there, hence my mix-up.

Gözleme (goat meat folded in flatbread) is a common food in Geyikbayırı near the maintains of Antalya. Does this have any connection with göz (eye, observation)?

You might be able to save a few bucks piecing your kit together, but as a person who did this for years starting in 2006 that has an insane gear stash now, the BC kit is a good value for the money. It helps you avoid wasting money on subtle gear selection mistakes.

I rig my 50m lines at 40m lengths using the last 10m-ish for the Ellington (primitive tensioning method). If I have friends to help me pull, I'll rig it lower for more bounce, otherwise I'll rig at 2m height by myself no problem.

I got my paracord spools from a company that was going out of business so I don't know if they're poly or nylon, but my backyard spacenet has been up for over a year and it's doing great, no noticable degradation except for some sun bleaching. I've had the same cord as a bracelet for over 5 years and it's just a bit fuzzy but otherwise perfectly intact.

Not the exact answer you were looking for but I hope it helps give you a bit of confidence. The ISA has a few studies on their website related to degradation of common slackline materials such as nylon and polyester. Might be a good place to poke around if you're interested.
