Anyone tried 8mm in ropeman 1?

I use a ropeman 1 on my oplux tether and linesman.... There is still margin. It is out of spec, but I feel safe with it. Your Mileage May Vary.

I have an 11mm tether that I could go back to if it did note feel safe

I'm doing the same and running a thicker carabiner.
Serious question...why would this be any less safe than running 9mm and a skinny carabiner?
 
2 years ago I used a ropeman1 with an oplux tether, it held fine for me, your results may vary

One concern I did have was the prolonged use of the ropeman in a specific section of the rope seemed to compress it. There was a section that seemed to be a bit softer than the rest of the rope. I contributed that to it putting all of the pressure on such a tiny section of an already narrow rope.

This year I've gone to a 9mm resc tech rope, which seems much better. Not sure if it's due to this rope feeling denser than oplux, or what. My evidence is purely circumstantial

Edit: if you're in doubt, follow the tested results of a manufacturer ratings, not some guy on the internets, it's your life that is at risk
 
With a thicker carabiner yes have tried. I dont see it failing, but use a lot more friction hitches anyway.
 
Currently using ropeman 2 with an Oplux linesman. I’m not a big fan. The linesman has to be completely offloaded to release the ropeman. It’s safe, I have no doubt, but not for me. I have a Kong Duck on the way.

With any ascender device, you should have to off load it to release it. I have not used a Kong Duck, but I imagine that will be the case with them as well

With a ropeman 1 on 11mm rope, you could release it under at least some degree of load. Probably not the safest maneuver, but I found it useful. The teeth on the ropeman 2 are really sharp and pointy… hence, their grabbiness. I think the duck’s mechanism is more akin to a ropeman 1. Guess we’ll see
 
Just a word of caution for those pushing manufacturers specs. I tried a Kong Slyde this summer. The min. recommended rope diameter is 9mm. My tether is 8.9mm dynamic rope. Close enough right?

I hooked up at ground level and spent 20 min bouncing, jumping, swinging, doing everything I could to see if the Slyde would slip on the out of spec rope. It held fine so I climbed to 20' and shot 6 arrows. I started to move around the tree and all of a sudden I was free falling. The rope pulled past itself in the Slyde and I went for a ride to the end of my 10' tether. Luckily, I was somehow able to catch the rope on my way down and slowed myself a little so when I hit the stopper knot it wasn't a sudden stop.

Even though I no longer use it, I have tried multiple times to replicate that situation at ground level and I have not been able to get the Slyde to slip again. I always tie an Alpine butterfly knot in the tail of my tether and clip it to my caribiner but, didn't this one climb for some reason.

My point of this post is simply to say manufacturers develop specs after a lot of careful testing. No amount of ground level testing will come close to the testing the manufacturer has done to develop the specs for their product. Something out of spec and tested at ground level, or even hunted from for a season may work, right up until it doesn't.
 
Yikes, .1mm was all it took! Dynamic ropes generally can flatten easier and might have been a factor. There might have been some twisting action on one of the sections due to your movements that also could contribute to the slipping past each other.

I would never advise anyone to ignore specs. I chose to use a ropeman on a smaller rope.

With all that said, comparing a friction device to a mechanical device is a little apples and oranges IMHO
 
I tried it on a tree in the backyard when I was about 1’ off the ground. Then I came to my senses and said “screw it, not worth death or paralysis.”

I wasn't comparing the two. I was comparing that both manufacturers publish specs and that a couple of minutes at ground level or even a year of use by somebody else may not 'prove' that a specific out of spec application of the device is safe. I'm also not sure why mechanical device specs would be less accurate than friction device specs.


Ultimately, people are responsible for their own safety, I was just highlighting an incident that I hope makes people stop and think for an extra second before ignoring manufacturers specs.

Another device that can be used like the Slyde is the Grivel Tris rigging plate, the cord can’t bypass itself and is forced to press against each other due to the circles.

What's your opinion of that Tris?
Does it adjust easily each direction?

You can do what you want but releasing a ropeman 1 or kong duck under load is a terrible idea. Both should be released under zero load. And I do not see any benefit to do so under Load. I’m curious as to why you would want to release it under load?

I was wrong about the Tris after testing it some more so I deleted that part. I think a too large of opening, either slot or circle, allows the section of rope coming from the top to push up the part it’s supposed to pinch, allowing the rope to slide freely. The picture shows the start of the pushing with 6mm cord, does it very easily if the Slyde twists a little. If it is set each time by pulling to the right before loaded it holds, but that requires remembering to do it each time.

If I’m climbing and need a little more distance from the tree to move my leg up to the next step is the circumstance I’m referring to. I still maintain 3 points of contact on the tree, push my hips back a bit and release some rope on my linesman’s belt. So not anywhere near under 100% load…probably more like 25%. Regardless, the ropeman 2 does not allow you to do even that.
