I've occasionally dabbled with walking on slacklines that people have anchored between two trees. I had no idea there were people out there planning spans this long with so many technical details and such. Glad I stumbled across this channel to learn something new. 👍

[@JoeKunsch]

I was bored today and watched the soft shackle button knot video and followed along. I used an old trailing rope, but really enjoyed learning a new knot! Thanks!

[@joelpapineau8555]

Following your channel for a couple weeks but never thought there would be an episode right next to my hometown! Just before I was watching the Moab line episode and now Québec 😂 what a change of landscape.

4:07 Be sure that the welder knows very well what he is doing. Heat from welding might cause the surrounding steel to become brittle and you might need to do additional heat treatment to prevent cracking the C beam right next to the weld. Several WW2 ships made of welded steel capsized for this very reason (and they blamed japanese torpedos until they realized the problem is the welds causing steel to harden).

[@HowNOT2]

That's a good point. What are the main things that cause a problem vs not? Leaving the heat on too long?

[@dangosselin8363]

You need to pre-heat your pieces before the Weld thats important and make sure that it does not cool down fast, that the main factor that cause cracking! And Also the proper welding material (Rod or wire)

[@harviecz]

@@HowNOT2 Steel comes in various "grades", each is made for different purpose and has different properties. also responds and recrystalizes differently during temperature changes. You have to read datasheet of the particular grade you are using and know the details of used welding process, to ensure everything will be able to withstand planned load. You should find certified welder, who has experience with structural welding and metalurgy. i am not such person, so i can't really tell you more. friend of mine once asked me to weld custom rappel device for him, but i had to refuse him for this reason. on the other hand, you can probably just test the setup for 2 or 3 times the maximal expected load (including shock-load) and should be OK.

[@mikearcher1184]

I'm a professional welder and I'm telling you that weak surrounding metal is not a problem good welds are the important part in this equation. Unless your welding in th ed artic your fine. Most climbers and slackers know nothing about steel/aluminum I work with it everyday you rd good

[@Lazybiker60]

The main thing is too, is that train tracks are made of high carbon steel while the channel is plain mild steel, depending on what it was welded with, heat input and temp of steel it could be absolutely flawless or it could easly crack 30” of weld with no visible undercut, crater cracks or any inclusions, once cooled down the crystallization is the major part, ive done no pre heat and pre heat weld on high carbon steel and cast steel and have had plenty of good welds with both but most failures came from no pre heat, or excess cooling

[@jcee2259]

I haven't needed a highline since the 90's. 2 people, Laughing Bear and I, put it up. He had the spurs and I was his only ground crew. It got the bigger rocks out of our cave entry dig

[@purple0burtle]

Everything seems to be super-safe ..... back-ups, extra anchors, redundant lines, rigging-plates etc etc. But the end of the line is the telegraph pole/post? How strong are these things? How deep are they planted? And in what condition is the wood? They look pretty old.

[@BlokeOnAMotorbike]

your average telegraph pole is 36ft long, 6ft of that is buried. They're tested every ten years, and can last over 100 years before they're obsoleted by underground installations or other reasons than they've decayed (because they're treated with chemicals that slow the rotting process and also to prevent wordworm and kill other insects that try to infest them). Heavy poles (~40-45ft) are planted 8 feet deep. Even the light poles (10-12 inch diameter?) can withstand the weight of a full grown man weighed down with gear hanging off of it, on top of upwards of a dozen or so multicored cables pulling in all directions and variable weather conditions.

[@RougeDane]

I used to inspect wood power poles. Our company didn't start to inspect a string until it had been in service for 20 years. And then a 10 year cycle started. The oldest pole I've ever personally inspected was dated 1947. In areas with permafrost they will break in the first 18 inches of soil from cyclical freezing thawing. I have red tagged poles on the first 20 year inspection. I have found many in permafrost areas that were completely rotted through at the base and only being held up by the wires. Location matters for the longevity of wood power poles. There are several species of trees used and different chemicals used in the treating process.

[@sebastianloessl7982]

When will you solo rig this?

[@BurchellAtTheWharf]

9:29 8-10 arm spans(fathoms) is 48-60 feet

[@sil8127]

Why couldn't the highline take the bad weather? Im confused what the rope does instead

[@HowNOT2]

The main and backup oscillate against each other and cut each other. A single rope wouldnt and it isnt a life bearing piece of system. We want the part we walk on never to exceed a certain force.

[@grosminetytp5520]

What about planes and helicopters, does it require a special authorization from FAA or something like that?

[@Stein1306]

yes it does

[@jordanrobinson9535]

I've found your videos as a climber due to being recommended the big wall series and I've become quite interested in this community. I agree with your statement that the smartest thing for me to do would be to find a slackline group near me that also does highlines however it appears my area doesn't really have a group going yet. What would be your recommendation to me to safely begin exploring this world without adding another entry to the SAIR? I would much rather go out with people who are experienced but in lieu of that I am still interested in learning and experiencing it regardless. I have watched a large number of your videos and I would like to know what blind spots I may have if I'm mostly basing my learning on them.

[@HowNOT2]

check out www.hownottohighline.com. I'm doing a school and if you would like to be one of the first students, I'll be ready in about 2 or 3 weeks to take on about 10 students let me know. Best way to reach me is on fb messenger. facebook.com/ryan.jenks.35 You still ought to find your local community as well. Where are you from?

[@magnetohidrodinamika]

could the glue from the tape spoil the webbing?

[@grosminetytp5520]

I don't know what are the chemical components in the tape glue but I've already seen some corrosion on aluminum.

[@martingravdal7094]

Did you come to any conclusion with the taping technique?

[@HowNOT2]

Unpublished for next few weeks. Too many other episodes to get out haha. kzbin.info/www/bejne/onq7hpttqJulfZI

[@mainemade300]

Each arm length is about a fathoms long ,how much is a fathom ?

[@heli400]

21:55 can confirm, yes! we are all lumberjacks!

[@error.418]

Isn't that more like a windlass, and not a capstan? AFAIK, a capstan would be vertical, a windlass horizontal. But they operate on the same principal.

what is the music in 00:29

hey! its just about 30 miles from my home. I missed that

So how much do those 50m Rope spools cost?

[@savaiiheaven8143]

What kind of ropes do you guys use?

[@apiletal]

Min 10. Why you use insulate tape? You can use wipping twine. Is beatter for fix the straps Good work. 👏👏👏 The best= the team

[@warpigs330]

Would have loved to see the line actually getting tensioned and people walking on it.

[@pascalras9421]

Sooo much work and so many meters of webbing and ropes! I was thinking this slackfest would be every year but I could only find information from the 2019 edition. Do those crazy quebecois are planning other editions of this slackfest?

[@jasminroux9031]

It happens every year but they didnt cross the mine hole in 2020 and 2021 they did highline shows and speedcontest instead

[@darrylhansson5715]

love slacklining, vereeniging SOUTH AFRICA.

[@martinkitevski7056]

You should highline on the big hole made by the asteroid that killed the dinosaurs !!!

[@badgerpa9]

That big hole is in the Mexican Cancun area. Most of the hole is under water.

[@sil8127]

Keep those fingers clear of that tape in that machine!

Just found out the city changed its name and is now Val-des-Sources, huh

[@cameronrohr2311]

As a lineman I feel like it may have been easier to use steel (guy) wire for the span and anchors probably cheaper to. Although I am not sure how that would affect the high lining. It's impressive what they accomplished though.

[@WorBlux]

No... Steel has a maximum self-supporting span of about 8 km. Any cable you suspend across the mine would be at 25% max tension. Making it segmented would put you at 50% max tension before you even get started (no way to get a safety factor of even 2 on a segmented design) If you can a 2 km continous cable - you're looking at 10mm min. - 2x1 ton of cable. If you need spliced you'd have to go bigger. Dynema is more than 10x stronger than steel at the same weight. As to anchors, I'm with you that an off the shelf helix or deadman system would have sufficed. , but they may be been permission/legal issues regarding permanent installations or excavation.

[@FocoNoals]

amazing vídeo!! namaste

Who's paying for all this? Looks crazy expensive 😳

[@dougthebuilder1]

But are there no concerns about everything being contaminated with asbestos? Seems high risk to be playing around, in the wind, in an asbestos mine.

[@juangonzalez9848]

I mean, that second pole was standing there for how many years, just fine. Then y’all thought it would be a good idea to cut it down. Hope you did something with the pole at least to get it out of the way.

[@damo485]

How Not to CHAINSAW!

[@WorBlux]

I don't trust the rebar loops in these sort of blocks for critical loads. There may be less rebar in there than you think, it's usually just a lift point made to last until the blocks are installed to stabilize an embankment, plus the blocks themselves are made with "hot" loads, no telling what quality of concrete went into them.

[@yannchevrier-foundy5063]

OMG this is so CEGEP

[@FallLineJP]

@25:20 - celebrating cutting down the pole, nearly chainsaws through the anchor... :|

[@LM-jr4gt]

so the fact this is an asbestos mine isn't dangerous?

[@sil8127]

Watch the Tom Scott video about the mine. Very interesting 😄

[@HowNOT2]

It wasn't until we walked a truck strap over it haha

[@heli400]

I believe asbestos is a solid rock that only becomes dangerous after it is processed by heating it to a high temp at which point it expands and becomes very light and porous, and thus gave its insulating properties, but this is the point at which it becomes unsafe to breath in its tiny fibres,.... well that's what I remember the abatement company told me about the vermiculite in my attic

[@LM-jr4gt]

Prairie Climber I didn’t realise it was after it has been heated that it became unsafe. Interesting

[@heli400]

@@marcushill78 cool, good to know, thx

[@sendit2873]

there is still alot of asbestos in the air and soil there

[@Remon_]

I dunno what's scarier, falling into the ground or falling into a pit of toxic asbestos water. Probably not too dangerous actually, but i dunno, i like the idea.

[@dr.doppeldecker3832]

Asbestos only is dangerous when you inhale small particles, the Asbestos then "clogs" your lung. Since the Asbestos is in water you can't inhale small particles. It only becomes dangerous when you rip it out of old walls and small fibers are all over in the air.

[@TrackpadProductions]

@@andybaldman There's only a higher than average danger if you _do it wrong._ Just don't fucking _do it wrong_ and you're just fine. And if you use your brain for a moment you'd realize there's less older people doing this for the same reason there's less older people doing high-jump, and pole vaulting. It's an _athletic activity._ There are older people doing it - I've literally met seniors who do this - there's just less. And even if there weren't, how the fuck would you know?
