cut resistant bridge

EyesUp

Has anyone heard of a wire core bridge? I would love to replace mine with one, but mabye there's a good reason I haven't seen them available.
 
I can honestly say that I've NEVER came close to nicking or cutting my bridge. I don't really see a point in a wire core bridge, unless you want to be uncomfortable while twisting / turning /contorting while your climbing.
 
I just made the switch to a bridge and the ease it can be cut is something I've been thinking about. Do you think the twisting could be avoided be throwing a swivel on the bridge?
 
EyesUp - the wire core bridge topic has been done here on treebuzz... it did not get a thumbs up.
I can feel your thoughts. I can remember when I switched to a 'rope' style bridge and it was a little funny for a few days. I got used it... just remember to change your bridge often! I do it every July and January. Keep it safe
 
Best to keep saws away from the bridge area anyway unless you also have a saw protective jock strap.

Why do people think this is a bad idea? I don't see how it could hurt anything. Whatever makes people feel comfortable and safe in the tree should be available.
 
Ive been thinking a wire core bridge might be nice and not so floppy. THe way a rope bridge sags down and flopes around makes tending more difficult and introduces slack into the system. Being cut resistant would be a good bonus. I have been thinking about how one could do a splice that would not interfere with the bridge. Wire splices are very bulky. I have not figured a dood way to make a nice cable bridge. Maybe thats why it hasnt been done?
 
I'd like that aerialist harness from the opening of the Vancover Olyimpics. Must of been a metal track where they had FULL range of motion and control. Even cut resistant.
 
Hey Kevin,
Adding cable to the bridge wouldn't solve the slack problem. Actually the weight might make it worse. If a stiff bridge is what youre looking for then why not add a strip of nylon like a large zip tie.
 
I had a couple made by our local wire rope splice place - starting at 1/4" and the two sizes up from there. I took it back off because of the ends being bulky, and my swivel getting stuck on them, then slipping over or off them - it jerks you.

Also, the extreme bend in wire rope isn't all that great - bend a wire back and forth a bunch and you'll know what I mean.

I watched the video of the guys cutting their bridge, and I thought wire was the way to go - maybe I didn't go fat enough - if you did, you might not have an extreme bend. But it will get pretty heavy, and your swivel won't slide well.
 
This isn't so hard guys.....just use some old chain or something.

I mean....you have lots of options. You could use some old saw chain OR be real hard core and use some round chain link. How bad would that be!

Yea, it might make your saddle weigh an additional 10 lbs......but hey....you can make a chain lanyard and really have the heavy metal look down...
 
Wire core flipline.
Wire core bridge.

Seriously how hard can it be?

Obviously no one thinks this is a good idea for some reason.
If one were available I would love to try it even if it means buying it with what limited money I have.
The security and peace of mind of not being able to slice through the thing that my life is hanging on would be well worth it. (though I have never come close to cutting my bridge, accidents can and do happen)

The added weight were talking about here is a matter of ounces. It's not gonna make a difference to production climbing.
 
I suppose another thought would be, If you bombproof your bridge, what about your climbing line. I believe there is more potential for cutting that.
 
Good point about your bridge being a possible hazard..

The bridge attachment points on the Ergo allow you to put more than one bridge on....that might be something to consider...

I am do for a new bridge and will be experimenting with new ideas...
 
Don't think for a minute wire core means cut-proof. Even a handsaw will cut a wire core flipline under load in one good stroke.

However it only takes about the pass of 2 teeth on standard rope.

I can say from cutting heaps of ArmorPrus (with Kevlar core strands) that even 8mm AP is LOTS harder to cut than typical 13mm climbing lines.

Here 10mm ArmorPrus is a popular replacement cord for bridges and lanyards.
 
Seems like a kevlar cover with a braided polyester core (for strength) might do it. For example a spliced eye bridge could be built then slide a kevlar cover over the eyes on one side. question is where do you find a kevlar cover :-)
