Rope bridge, finally. Now what knot?

Okay, I see where you're coming from with the cams, however, I don't think it's an appropriate comparison because of the different standards the larger devices fulfill.

The notable distinction, as I see it, is based on how well suited a levered descender is for rappelling, vs beyaing a climber like rock climbers do. Belay devices with levered cams, including the Lifeguard, whose design isn't well suited for rappelling are excluded from my comparisons, for that reason.

Banjo Skank, probably not worth bothering over.
Stick to what you are happy with and what works :)

Yeah, I was just trying to be funny. It’s hit or miss.
Nothing against the adjustable bridge at all, but you’re right, I’m just really satisfied with the stock bridge on the TreeMotion. I do enjoy watching from the sidelines as a bunch of bright minds get together here and try to improve the gear and techniques of the industry and share ideas. Some of the discussion goes a bit over my head, I admit, but I absorb some of it, especially if there’s pics or videos lol.

@agent_smith , I don’t mean to pry and feel free to not answer or tell me to buzz off, I can take it, but I’m just curious what you do. Engineer seems likely. Are you with Occupational Safety and Health? Or your country’s equivalent of OSHA?

@agent_smith ... Size, by definition, may or may not include a subject's weight, but please don't have another cow when it comes to hashing out semantics, like you did when comparing two items of similar size with one item being half the weight of the other, which you conveniently overlooked and balked over when confronted with the reality of that fact, while using condescending insults in your defense.

I am happy for you to continue these type of comments - I am also happy to be the target of attacks, and to be the assumed villain.

Whats happening is that you make inaccurate statements - I correct them - and you don't like it. As stated, I'm happy to be the assumed villain.

I think you should go back and read your posts and my replies.
I think you have selective memory - in that with regard to 'weight' - very early on I pointed out the following:
[ ] Roll N Lock = 80 grams
[ ] Safeguard = 154 grams

I pointed out that yes, the Safeguard weighs more but, I stated that if 154 grams was a concern, then you have much larger issues to deal with.
I also provided photo comparison showing size - they are similar in size.

which you conveniently overlooked and balked over when confronted with the reality of that fact, while using condescending insults in your defense.

I am happy for you to continue delivering insults.
I went back and checked what I wrote in reply to your comments - again, all I am doing is pointing out facts. You may not like being corrected - and so you interpret it as an insult.

Here is another extracted comment from you:
when I say that the Safeguard and Grigri are subjectively on the low end of the cam size spectrum, compared to similar devices like the Rig and ID, all in the same class of handled descenders used for tree climbing
Click to expand...

The cam on a Safeguard is substantially smaller than the cam of all GriGri's.
Also, the Safeguard is significantly smaller than GriGri's or any other brand of braking device (with the exception of the CTOMS 'Quickie').

I have (almost) every self-braking device and can physically compare them all side-by-side. The 'ID' and the Sparrow 200R have the largest cams. The latest iteration of the 'RIG' has a smaller cam than its big brother the 'ID'.

Both the 'Safeguard' and its sister device the 'Lifeguard' are a substantial physical size reduction from other self-braking devices on the market.
The Safeguard has an 'instantaneous catch' - on account of the spring being removed. This makes it unsuitable as a belay device for lead climbing.

You also got some basic 101 physics incorrect when you declared mass to be the same as weight (which it of course isn't).
...

All of this is immaterial but needed to be pointed out to you.
In the context of a tree climbing harness rope bridge, I have found that a 'Safeguard' is fit for purpose. But that's my personal view. You may not like it - and nobody can force you to like it.

I would also comment that any end user modification to PPE (eg a harness) will generally void the manufacturers implied warranty - and also won't be approved by the manufacturer. Be that as it may, there will always be innovators who like to make improvements to extract more efficiency from their PPE.

If we all agree to agree that you are without a doubt the smartest dude here will you please fucking stop? Pretty please?

Are reading JohnXP posts or mine?
Are you being selective?
Or are you simply ignoring JohnXp and just focusing on me...am curious?
...
And no - I thought you were the smartest dude here?
There are an infinite supply of people smarter than me :)
My knowledge is only at a basic level (sorry).
 
Yes - it is priceless :)
This treebuzz forum is the wild west - you can say anything, selectively read posts while ignoring others, and get away with anything!
I am happy to be made out to be the villain :)
Please continue...

Playing the sympathy card... nice move. Not sure if it's arrogance or just chutzpah. Like the orphan begging the judge for mercy after killing his parents.

Happy for the insults to keep rolling in.
Also happy to be the assumed villain.

I don't think you even know why you are posting anymore - I mean, what is the point of your insults?
Clearly, you don't like being corrected?
I guess that is the root cause of your continued insults?

I wonder if people actually bother to read all of your posts and the replies...or if they just randomly assume I'm the villain and roll from there?

It really is the wild west!

Please continue :)
 
Big mistake is allowing the tail to go thru and inline and out of the rig paw or ring and plate. the bridge should go through and turn back in.
Reason being, one could clip into the wrong side of the bridge that is the free side of bridge ie the area between the knot and plate/ring outside of the captured bridge.
That would be disastrous!

Are you saying you should pass the bridge through a second hole before tying the stopper?
 
Have you seen or handled the beal birdie? It looks quite similar to a lifeguard, I don't know about its size though.

Although these questions are drifting off-topic...

People keep telling me; "He who dies with the most gadgets (toys) wins!"

Almost every year, someone tries to bring to market the next big 'GriGri killer'...
Camp tried this with their 'Matik' - which failed to knock any iteration of GriGri off its throne.

Video link:
Webpage: https://sport.beal-planet.com/index.php?id_product=1458&controller=product&id_lang=1

It wouldn't be 'fit for purpose' within a tree climbing harness rope bridge' (my opinion).
Anyhow, no - I don't have Beal Birdie... I am more interested in how things will develop with miniaturization.

The CTOMS quickie is nice but, it is mostly the realm of tactical / military market and restrictions apply with regard to how it is sold. But the Quickie has rope diameter limitations.
Rope manufacturers are driving this miniaturization - they keep making thinner ropes...

...

With regard to the original posters question re stopper knot.
The #526 Ashley (Oysterman) stopper knot is very effective. And, it can be beefed up easily.

My other favourite is #579 Double Three-Ply Stopper knot.
The dude on this youtube video does a reasonable demo...

If you dont mind me asking, are you a day to day working tree-man, a weekend warrior, a rec climber, or a tinkerer? Curious..
 
I'm still not sure what you mean, that doesn't look any different to me than doing it the regular way, except the Kolibri has a slot and not holes like most saddles.
