So on some big wall forum post (or mtnproj or supertopo - who knows - ONE of the many climbing forums I read while in class..) I came across this video of a guy demonstrating how jugging a fixed line running over a 90 degree edge can SEVER the rope after like 6 or 7 small bounces.. it also showed the same guy demonstrating how rubbing the rope against an edge during a pendulum can saw the rope in half after just a few goes.. does anybody know what video I'm talking about?? I wanna show a friend. Could not find it on youtube or anywhere..

PS in 'real life' my rope seems to rub against edges like crazy on rappel and even while jugging - and it's never even cut the sheath, let alone sawed it in half! How likely is this to actually happen? I wish I had the video so I could POST IT so people could watch it.. SOMEONE FIND IT PLEASE!! I don't wanna die. Thanks ;)

Hey! I just looked all over their site, can't find it. I contacted them to ask where I can find it.. I will post it once I do but in the meantime, anybody know which vid I'm talking about? post the link if you do :)

I pretty much core shot a rope jugging one pitch on it (2 people) when I ran it over an edge near the anchor.

Here.

The vid is at the bottom.

The only time I ever jugged a rope it was set up by 2 guys with years of big wall jugging experience. I ascended the rope 120 feet to find just three strands of kermantle still intact, the rope had been sawing itself against the coarse granite the entire time I was jugging up, had the jug been 30-50 feet higher I probably wouldn't be around to write this. I'll never forget the sheer horror I felt when arriving at the top and seeing the rope nearly cut through, needless to say, I don't jug lines anymore, not to say I wouldn't again but I sure as heck would make sure it was set up better before ascending.

My buddy and I core shot a brand new 10mm static line by one person jugging 100 ft of line running over an edge. Be careful.

Thanks for the lesson gunkiemike! Threes strands of kern left, mantle sheared through.

Jake Jones!! you found it :) thanks so much

You're welcome.
