I like the idea having the harness or bosun's chair attached to a primary winch serving as a method of descent. Attaching the bosun's chair to one ascender and a loop for the feet to the other ascender seems like a great idea for a lazy, middle-aged man like me! I'll give these methods a try. It works for a lazy, middle-aged man like me. Just stand up in the loop and raise the upper ascender with the bosun's chair attached to highest height where you can still sit down. Then sit and raise the lower ascender with the loop maybe a foot (if you're lazy) or two (if you're in a hurry) ... go at your own rate. Then stand up in the raised loop and raise the chair again. Repeat as often as necessary. Reverse to descend. I've found that since I have to raise the ascender slightly to get it to unlock while descending, I have to make more frequent and smaller moves on the way down. But I still wouldn't use a descender. Of course I'd rather have someone winch me up. But I frequently work on a boat alone and have to make due with what I have. I've used the same setup for climbing trees as well. Steve |

Tie it to a squirel. Duh. The normal way is to throw a line over a branch, pulling a heavier line with that if required. Tall trees can be done in a series of pitches, wher you first climb to one branch, and then throw a rope to the next branch and climb there. There are also fairly safe ways to climb a tree without a top rope. The first guy up attaches to top rope, others follow by climbing that rope. |

Steve How do you get the line up in the tree to start with? Throw a weighted end a over a branch then let it fall all the way down and tie it off to something sturdy, like another nearby tree. I don't feel like hanging from a grappling hook. And I test it with some really good jumps on the rope before climbing. Also check the rope for chafing before using it. Steve |

How do you get the line up in the tree to start with? I do something like this to put long wire antennas up into trees for my amateur radio. I use 40lb test spider wire (fishing line, walmart) which I spool off on to the ground. Then I tie a metal nut (hardware store) to the end of it and fire it up into a high tree with a slingshot. The nut will fly as high as you dare, arc over, and come back to the ground. Then I tie my wire antenna to the nut and pull it up into the tree. You could do the same thing with climbing rope. Works great so long as you do not get crazy and fire the line up too high over a bunch of trees at once, which is easy to do with a slingshot. This all works even better if you have the fishling line on an actual reel like you use on a fishing pole because the line does not have any chance of getting tangled up like it can when spooling it out on the ground. It is also easier to reel in your line after you have attached the antenna to the end instead of winding it back on to the spool. But I do not like to carry that reel while camping, and I am very careful when spooling the line out on the ground that I do not tangle it, so I do not use a reel. |

Using an old/cheap spin casting reel loaded with light fishing line, and a slingshot. Thanks for the idea! bob s/v Eolian Seattle WA9BVE |
