What do you want us to test???

[@Deckzwabber]

What's the effect of machine washing on climbing ropes?

[@Salmontemaki]

Good question

[@kevinwatson3190]

Better than handwashing only in a front loader though

[@Salmontemaki]

@@kevinwatson3190 why?

[@Rock_Appreciator]

​@kevinwatson3190 That's my understanding as well. I don't have a front loader so I've always hand washed it in a bin or the tub lol. I use just warm water personally.

[@leveller4]

Front loaders don't have an agitator for the rope to get snagged on, pulled, or rubbed.

[@GarsonLilley]

Start looking at industrial use cases, like welding splatter, sandblasting, water blasting, painting. Shit like that.

[@Guilherme-xg9yh]

I second this

[@piguy5450]

i work in arenas and this would be most helpful

[@wrenpowers4947]

I would like to see more arborist/ropes access work content

[@jamesweir139]

I would like to see some arborist specific situations. Looking forward to seeing this test!

[@Guilherme-xg9yh]

Love to see this sometime soon

[@wasatchpilots619]

Rub a dirty rope and a clean rope on a carabiner or friction device to see wear on hardware.

[@beachyGreg]

Have you tested using PL construction adhesive for glue in bolts? I assume it won't be good enough

[@Matrix7041]

What is the effect of isopropyl alcohol on webbing? I use it to decon my harnesses

[@harlanstockman5703]

I have soaked nylon in isopropyl for a week. If you let the nylon dry before testing, the iso soak has no statistically significant effect on strength.

[@Zogg1281]

Used to work in a outdoor centre that was in a REALLY sandy area. Every time it rained the ropes would end up covered in sand and wood chips, from under the activities, and end up looking a bit like this!!! Maybe not quite as flat 😂😂😂

[@ronl7131]

Goosebumps

[@lewisrichards6572]

Sounds good!

[@andyanderson2143]

This, i want to see this! Maybe with time-lapse and a cycle-counter in the corner of the screen!

[@jonathanzimm5511]

Two times the same rope one with dry treatment, the other without rubbed with dirt. Also two untreated ropes where both got thrown in dirt but one gets washed before rubbing

[@n0pe213]

Are we gonna get more full videos with the rub rig?

[@plb1917]

I want to know how groovy I can let my carabiners get before I should retire them. For a variety of uses. Carabiner blocks vs clipping in my rappel device vs other.

Speed heat tests on descenders

[@kirk9671]

Can I use my climbing carabiner for sailing. I have a 45 foot catamaran and am using them as job preventers. They open nice and wide. I worry they are too weak though.

[@stusue9733]

Catamarans are a good way to break things.

[@harlanstockman5703]

Are aramid/HMPE-sheathed ropes really more abrasion-resistant than tightly-woven polyester-sheathed ropes

[@keithb3989]

Could you please test the stretch of ropes. Indoor sport climbing dynamic rope especially. For example when I'm belaying and I have a 6 foot length of rope out and the climber is clipping, that might be 10 feet of rope out. How much stretch at its lowest point does that equal in inches or feet stretched.

[@kenferrin7350]

Roughly 30% for most (new) dynamic ropes. The more its use, the more it’ll stretch.

[@keithb3989]

@@kenferrin7350 I understand the percentage listed on every new rope, but I want to know the actual lineal feet or inches it stretches when a certain amount of rope is out during each climb.

[@alexambro4998]

Can you have an ascender on a rope cyclically loaded to a couple kn to simulate the damage the theet do to the rope? It would represent an absolutely worst case scenario since the ascender keeps stressing the same point

[@ed-ey1yb]

Absolutely would like to see how the Edelrid bulletproof line fares. Would like to see data to support my investment :)

[@dapperwounded]

It’s not long enough but she said it would be strong enough

[@phkit420]

dunno if you’ve done this before but Could you blunt the teeth on a micro traxion and test it for a top rope solo scenario

[@Rock_Appreciator]

Not quite what you're asking but in the TRS video they did a while ago they put tape over the spikes and did some drop tests. If I remember right, it slipped a bit and was more unreliable but still did kind of decent. It does have a cam function as well, so it is actually grabbing the rope and not just relying solely on the spikes grabbing the sheath.

Congratulations. You have out creepied Michael Stevens.

Is cut resistance better or worse when its loaded?

[@grignaak9292]

Cut resistance is much, much worse under load. Hard is Easy has a video on this.

[@ggs4989]

@@grignaak9292 If you're referring to the video I think, then he didn't test cut resistance. He tested abrasion. I'm just asking about a dirty rope's cut resistance versus a clean rope's cut resistance.

[@grignaak9292]

@@ggs4989 Ah! I thought you meant "under load." not "loaded with dirt." My bad. I believe it is the same video on abrasion, there is a minute or two where they took knives to ropes.

[@FxdGearQueer]

​@@ggs4989He cut a sling with a kitchen knife while hanging from it. Mega sketch! But the result was as expected, load + cutting force = ☠️

[@ggs4989]

@@FxdGearQueer right, it is expected. My question is about the force required to cut it. E.g. would falling suddenly on an arête like in that viral video require more or less force when the rope is dirty. You can imagine a rope with an inch of sand around it held together by fine netting. Cutting into that would simply move the sand around and destroy some of the netting. The edge would be deflected and abrated to some degree by the sand. Same principle (hypothetically) for a dirty rope, except the sheath is the netting and the sand is the dirt and gripe in the sheath protecting the core

[@Jookyforever]

Ropes with spots that barely do or don’t pass the little rule of thumb bend test things

[@kenferrin7350]

If you are talking about the “pinch test” that’s not really a thing. It’s was made up or told to by salesmen than don’t know what they are taking about.

[@Rock_Appreciator]

It'd be nice to see some further testing on various types of sheathes & cores on dynamic, and benefits/disadvantages of them, brands etc... How much force to cut it, few basic abrasion tests... I'd even appreciate some arbitrary ranking system like ""4/5" rating or a tier list or something lmao.

[@BigEgoGaming]

Grappling hook rope on the train track this scenario being that you throw a grappling hook up it accidentally hooks onto a train track with a train. I want to see if that ropes holds or break with the weight and wheels of the train.
