Re: tech cord question
I wont comment on the whole situation, but as long as its the mixed tech cord, with technora and vectran, you're good to go. If its the vectran one, it can be self abrasive.

Re: tech cord question
Personally i would use it to make an eye and eye, because youre gonnas wear it out from friction before you need to worry about self abrasion coming into play, but thats just me. It all comes down to regularly inspecting your gear, if you catch it self abrading, just retire it.

Re: tech cord question
How would you notice it self abrading? I use mine as a footlocking prussic. Want to make sure i retire it, before it retires me.

Re: tech cord question
The abrading is happening most commonly in places where there is an internal crossover. being its a hollow braid, you could just bunch it up and peek inside to see how its holding up, or use a small fid to just open up the braid a touch. Also, in some cases you can feel the irregularity that occurs when it starts to disintegrate inside. But like I said, if you have the mixed stuff, which I think is all they're making now, but dont quote me, then it shouldnt be a concern.

I thought Technora was self abrasive and Vectran was not. The failures that happened were bridges made with the pure Technora stuff.

Just to be sure,I just wanted to know if there was anything wrong with Allgears tech chord? I didnt know if the bridge recall was due to the chord or the splice? Thanx!

There is nothng wrong with All Gears Tech cord. It was the application it was used for. There was absolutely NO research done on All Gears Tech cord used for a harness bridge. It was the wrong choice of cord to use for that application.
What is your application for this cord?

Technora IS self abrasive, posolutely, absitively.
Vectran fibers are very slippery.
This is how misinformation is passed. Please, Please, Please don't post anything regarding fibers unless you are 100% sure.
I think the 'mixed tech cord' Shawn is talking about is the TVP, which is advertised to be equal blends of Technora, Vectran and Polyester.
ONLY use what the Manufacturer recommends as a replacement bridge.

Spread the outside fibers apart to expose the inner fibers. Keep it open and shake it over apiece of 8.5X11 white paper. If small particles of fiber land on the paper, it's self abrading. It's very noticeable, they are about the size of 'beach sand'.

Re: tech cord question
My apologies Norm and all, you are correct, I got the two switched around in my head that day, and have since been corrected by John as well, my sincerest apologies. I in no way mean to spread misinformation, and I thank you for your correction.
I am aware of the new TVP, which seems like a nice cord, but I was speaking of original tech cord. The way John was explaining it to me was that originally it was too high a percentage of technora, and that it has since been balanced out with vectran, to eliminate some of the abrasiveness. That was the reference i made to "mixed" stuff or the pure technora. I dont know how long ago the change was made, but now all we get is the blended technora/vectran tech cord, which is fantastic stuff. wears well for me as a hitch cord, just the right bite. One of the climbers around here has been on it for a while now, and I know he likes it. But regardless of the material blend, the end user still needs to regularly inspect for wear, decay, etc.
Thanks again Norm, and apologies.

Re: tech cord question
While I am not currently at liberty to discuss the full details from my recent rope bridge failures involving the All Gear Tech Cord (http://www.allgearinc.com/AG16STC.htm)I can say that the cord used was not chosen at random. I would never have used this cord without explicit assurances from a manufacturers representative that the cord was applicable for purpose.
It is very important to note that the All Gear Tech Cord (http://www.allgearinc.com/AG16STC.htm), Atlantic Braids Techline (http://www.atlanticbraids.com/assets/products/Techline.pdf) and All Gear TVP (http://www.allgearinc.com/AG12STVP38.htm) are all completely different cords and are not interchangeable for all uses.
When I can release the full results from the testing that has been performed on my failed bridges I will certainly do so.

Norm, I am only making eye n eye tails out of the last of the pure old Tech chord. I was wondering how it holds up just for that use? Right now I just have it as a hip prussic on my lanyard.

For best results, call All Gear and ask their opinion.
I will tell you that I have a 'secret weapon' made from the 16 strand 5/16's" diameter tech cord you are speaking of. I have been using it to work off a 7/16's" static line when I SRT up, which is 90% of the time now.
I also made a secret weapon out of the TVP 5/16's" 16 strand cord made by Atlantic Braids and sold by All Gear Inc. I like the TVP better, due to it's nicer flexibility.
I've also made eye & eye's from the TVP, which is what I had Sterling Rope break. I still like 5/16's" HRC the best for hitch cord.
I can take pics of the secret weapons if interested??
