New experimental attachment method.

I am considering replacing the Slyde with a single link from a grade 120 lifting chain from McMaster Carr. Gonna mock up the hole opening in wood to make sure I can fit enough ropes through the opening but I think the math checks out.

The Chain I'm looking at is powdercoated steel with a stated capacity (not mbs) of 5, 200 lbs. I would buy one foot and use an angle grinder to cut every other link. Yeilding 7 links. 2 for using and 5 for abusing during testing before I use them.

Would a 28mm aluminum ring be too large for this?

I think the piece that gets inserted into the loop (I'm gonna start calling this the dogbone) would have to be rather large diameter for the 28mm ring to work. But I could be wrong.

28mm comes out to 1.1 inches so with a 1 1/8" hole through some plywood it could be tested pretty easily for viability. may be worth adding to your wooden mockups list to see what looks better in hand

Yeah I'm all for new ideas but I'm having a hard time with this one. Why replace a piece of metal (delta or oval link) with another piece of metal (link from McMaster Carr)? If you've got to replace the link with something, why not a non-metal component? I toyed around with a jam knot a while ago and it works on the same principle as what you're trying to do here. Goal being, not allowing the knotted tail end to slide through a given loop by means of constriction.

I have used jam knot and I like it and I feel it works for some situations. Getting around branches is fine. Working on a system to use for taking down a rappel rope a different story.
I’m feeling adding the plastic piece in a mix is something I would have to play with for next season. Not ruling anything out till I try it.

I have no problem with delta links being metal. It's the screwing and unscrewing that I don't like.

Would love to see your jam knot.

If you don’t mind metal then use a carabiner. If you don’t like aluminum, use steel. By far the quickest around limbs, setting up, taking down. Etc.
 
it's a creative idea and i liked thinking about what would happen if the jam section of rope ever pulled through while the stopper knot did not....it seems like the tether would always stay girth hitched so long as the stopper knot didn't pass no matter which way you pinch the rope bight through the metal/can be flipped (but i'd check it with paracord)

@gcr0003 mentioned metal carabiners.....they make diesel steel locking biners that are a little heavy but i'd have no worries about sideloading with them

my gut says once you weighted these while using dynamic rope that you might find they take a little effort to unjam up (i think the mild stretching of dynamic rope might make this bind a bit more)

i know a delta link is a pain, but it really doesn't take much time

i wouldn't use this method based solely on i don't use methods with my life support that haven't been used extensively by others for years....i do all sorts of novel stuff with steps, sticks, and even platform attachment....but not with tether, lineman's, bridge, or saddle

PS and after looking again, i don't think this will grab the tree good and your wrap around the tree will not be close to parallel to the ground

the part of the rope that is pinched through the loop and has the stopper inserted will very likely not advance through the metal when weighted because being pulled into the metal slot and then pressing hard onto the stopper rope will create so much friction that it will not choke the tree
 
Without discounting your attempts at a new idea, might I suggest trying the "SNEAK" hitch? I have finished another season using it exclusively. It is metal free and very easy to release for branch passing.
 
Well I actually came up with it on my own while experimenting in the yard trying to establish a way to bypass limbs while one sticking or 2TC. A month or so later I saw another guy had posted a video of kind of the same the method on YouTube. So don’t know who was the originator but I was for me lol. I’ve tied it on several different ropes, the pictures are Sampson predator rope with 7mm Sterling hitch cord!

@Brocky talked abt it first as a challenge I believe, and I made a video demonstration of it. It was all in a thread very similar to his one.
The idea does have the challenge of not being auto cinching. Depending on which friction hitch you use determines how much effort to snug it up and the release it.

Oh I believe you! Many ideas can be thought of by multiple people!
I will suggest to try @Red Beard idea and the "SNEAK" hitch just to compare them all.....you might change your mind or be more sure of your original thought?!
 
I spend lots of time, like many others trying to come up with new things, that being said sometimes I’ll come up with an idea that I like, just to find out someone else had already tried it and posted it on YouTube! I don’t know how to post on YouTube so never put any ideas out there unless I share them here. Your video was the one I saw a month or so later on this subject, top prop’s to whoever originally thought it up because it makes climbing much easier when passing limbs for me. God Bless!

yeah, on a bigger scale newton and leibniz both invented calculus at the same time independently

i was working on using daisy chains to make a trucker's hitch and developed my system for it with steps and then posted it here only to find out another user like a week or so earlier had posted a video of the same thing but using it on climbing sticks...i had no idea anyone else had the idea also
