Plinko Posted February 9, 2004 Posted February 9, 2004 (edited) I'm looking for a emergency bail line/handline for scrambles and alpine stuff, so I don't have to bring two full-size (10mm)lines. What do you use, and how long? I'm specifically looking at the New England Tech Cord, 5mm (3/16), 5000lb. Thanks all... Edited February 9, 2004 by Plinko Quote
scott_harpell Posted February 9, 2004 Posted February 9, 2004 are you serious? 5.5mm spectra is way too thin and slippery to rap on. Have you ever rapped on doubles? It is slick. Now think about 2/3 the diameter. Plus, that shit is expensive! Quote
JoshK Posted February 9, 2004 Posted February 9, 2004 I bought some 7mm cord for emergency raps, and I would pretty much just use that in an emergency. ANything smaller is asking for trouble. Quote
Doug Posted February 9, 2004 Posted February 9, 2004 I have a 8.2 mm glacier rope and have rapped on it a couple of times, but it's a sphincter puckering proposition with my fat ass. Quote
Marko Posted February 9, 2004 Posted February 9, 2004 (edited) I often use 6mm perlon for a rap line in tandem with a standard lead line, or sometimes by itself when soloing. If you're using a rappel device you can gain more friction by clipping a second biner into the ropes and to your belay loop. Make sure you clip into the ropes AND into the harness though. If you clip into just the ropes you'll get even less friction. Â I don't think I'd ever use Spectra for rapping. Because it's so stiff it gets wicked tangles in it. You'll be F.U.C.T.! Â Cheers! Â Oh yeah, and make goddamn sure you direct the rope away from any bad edges... Edited February 9, 2004 by Marko Quote
layton Posted February 9, 2004 Posted February 9, 2004 I use 6mm perlon also. Here is my system. At the anchor I tie the two strands together w/a death knot with the knot on the skinny side of the anchor. Then I tie a fig-8 on a bight on the skinny rope very close to anchor and clip a biner to it. Then I clip that same biner to the lead line. This way when I rap, all my weight is on the lead line. Â The big problem with this setup is that you MUST PULL the skinny line and that is #1) a bitch and #2) bad juju if the rope gets stuck cuz then you gotta lead or jug up a 6mm rope. Â However, I have pulled my ropes through some shit and have never (serious knocking on wood) got them stuck. If one was to reverse the knot (no biner, fig-8 etc) and pull the ez pulling lead line, the 6mm is sure to get wicked stuck as it tumbles down in all it's twisting knoting glory. Quote
layton Posted February 9, 2004 Posted February 9, 2004 one more thing. DON'T RAP ON SPECTRA. I have no idea where you found 30-60 meters of that shit, but concider it's low melting point and the large amount of heat generated on rappel. You will die most certainly. Quote

snoboy Posted February 9, 2004 Posted February 9, 2004 Ever hear of a Monster Munter?? It's very applicable to this discussion. Quote
Bug Posted February 9, 2004 Posted February 9, 2004 I use 60 m of 7mm perlon for alpine soloing. It is light enough to not be a big concern. It is strong enough to double and lead on. It is long enough to rap off lots o stuff. It handles pretty nicely which has been a good thing late in the day/night a couple times. Quote

If it's over your head and you've got no clue (typical) and you can't answer the question then don't waste everyones time by taking up board space and talkin shit...if you wanna troll and throw down, that's what the Spray board is for.  If anyone else has used Tech Cord, or knows more about it than lumm, I'd love to hear more...

rbw1966 Posted February 9, 2004 Posted February 9, 2004 I've rapped a single 5mm line before while canyoneering in Zion. You'll want to add an extra biner to increase friction. If thats not enough you can throw a biner on your leg loop and redirect the brake end into it. As someone else pointed out, you'll want to make damn sure its not loaded over any edges at all. At that diameter, you don't get much room for error. Quote

catbirdseat Posted February 9, 2004 Posted February 9, 2004 Hey, you knuckheads, Kevlar doesn't HAVE a melting point. It will char before it melts. Where are you getting your data anyway? Quote
lummox Posted February 9, 2004 Posted February 9, 2004 Hey, you knuckheads, Kevlar doesn't HAVE a melting point. It will char before it melts. Where are you getting your data anyway? i get the info from the infallible world wide web. the information superhighway. check out http://www.justsail.com/rmaterial.htm i am of a mind that the 500c temp is a material science joke. something with 'curie point' as the punchline. oh. you dont have to use a bic lighter to melt kevlar with btw.

snoboy Posted February 9, 2004 Posted February 9, 2004 This is intersting to me, because I have been wondering what to buy as a self evac line for getting off a dead ski lift when I am patrolling. Don't wanna carry around 35m of 7mm if I don't have to. Quote
rbw1966 Posted February 9, 2004 Posted February 9, 2004 I read something a while back noting that ski patrollers in CO use 5mm cord for just this purpose. Quote

Don't wanna carry around 35m of 7mm if I don't have to. I've seen people use 5-6mm for self evac w/Rescue 8's Quote
snoboy Posted February 9, 2004 Posted February 9, 2004 I was thinking of 5 or 6mm with a monster munter, but then I thought that spectra would be a good (but expensive) alternate, because it could be a handy glacier rescue rope for ski touring as well. I don't think I would want to put crevasse rescue kind of loads on 5/6mm perlon. Quote
