Let's say that at a belay, you're trying to get slings of variable length to terminate in a common "power point". You can decrease a sling's length with a "tornado knot", which starts like a fig-8, but has several wraps around the sling before plunging through the final loop, thus shortening the sling's length more than other knots might. After 18 years of climbing, this is my only contribution to the advancement of mountaineering.

>>>clove hitch into belay, fast, clean and bomber<p>Not so bomber, as it turns out, it will pull through after x many pounds of pull. Don't make it your primary anchor knot.

<blockquote><font size="1" face="Verdana, Arial">quote:</font><hr>Originally posted by JayB: <strong><p>Anyone care to explain the nuances of the bomb-coil? Sounds cool, I've just never heard of it until now.</strong><hr></blockquote><p>JayB,<p>Let's see if I can explain this well: First off, set the rope up for rap/TR, and secure it so it won't feed through the anchor. Then, starting from the end of the rope to be tossed, make a whole bunch of small coils, either butterfly or circular, in your hand. By small I mean about a foot to a foot and a half, from your hand to the bottom of the coil. <p>Once you have a nice big handful, take a bight of rope and pass it through the center of the coils, then bring another bight THROUGH that bight and cinch it down over the top of the handful. <p>The idea here is that you've got a compact wad of rope, and when you pitch it the extra weight at the end will carry it more where you want it to go. When the rest of the rope comes taut on the anchor, the weight of the "bomb" pulls the second bight out of the first, and whole thing falls apart, as neat as you please-- if you did it right. It takes some practice, but if you like rope tricks it's pretty cool. And it definitely makes tossing the cord in wind a lot easier...<p>m

At the end of a self rescue class once, we were presented with a list of situations to try and get out of. One was:<p>Lets say you were stuck up on a blank wall(no features to downclimb) with many rappels to the ground. Each station is 50 meters apart, so you would need two ropes to get off. Problem is, you dropped one of the ropes, and are stranded with only one chord! Getting off the cliff is a matter of life or death, waiting for a rescue is not an option (no one will ever come.)<p>What do you do?<p>One solution was to use a funky knot that I once learned in Boy Scouts. I forget the name, but it might of been the Sheet Bend (I'll investigate that.) It is used for shortening a length of rope without cutting it by folding it and wrapping it around itself.<p>The knot is two difficult to explain, but the basic jist of the knot is that you bend the very end of the rope into thirds and wrap it around itself(you can look it up in the boy scout handbook). This bend will hold under tension, but Only under tension, if unweighted the "knot" will come untied. <p>Here is the catch... You fisrt fix the end of the rope to the anchor. Then you create the Sheet Bend. You weight the rope, then take a knife and CUT one of the three strands of rope that the bend creates [img]images/icons/shocked.gif" border="0[/img] It is esential that you cut the right strand or the knot will fail (make sure your backed up to the anchor while doing this!). Be sure the knot holds, unclip your daisy, and rap off! Just be sure not to stand on a ledge or unweight the rope untill you are down to the next anchor. Once down and clipped in, unweight the rope and flip it around a bit, the Sheet Bend will come untied and your rope will fall.<p>Now many of you will say that this is a crazy idea, but think about it; would you rather die quickly while trying to live, or hang out and suffer a slow miserable death on the side of a wall?
