Hey Guys, in case you have missed what was happening on the Lazy or Clever thread, several of us have perfected a homebrew power ascender that simply uses a heavy duty cordless drill for the power. The other end is a RollGliss emergency descending device made for drilling rigs, high construction work, etc. The business end of these gadgets grabs the rope the same way a Wraptor or other commercial power ascender does and the device is easily modified to work with a drill. Now, the things are not normally cheap, costing about two grand, BUT here's the cool thing: a guy on eBay right now is selling off several dozen of brand new ones for $160. each (another hundred or so for shipping) AND, even more amazing, they come with 450 feet of expensive kermantle line, a waterproof backpack carrying bag, a bunch of nice nylon straps, a pulley, and all of it in a really neat watertight hard case. It is an unbeatable deal. A number of us bought more than one. If you check over on the Lazy or Clever thread in Climber's Talk, there are photos and details of what we were doing. These r500 devices are rated for a load of two men and legal in industry for life saving, rescue, and life support, so there is nothing dodgy or questionable about using them for our own purposes. Of course, I am not advocating their professional use over buying a proven device like a Wraptor, but those of us who are just rec climbers, or otherwise on a tight budget, may not have the approx. $3600. the Wraptors cost now. Even if you buy a heavy duty cordless drill to use with one, total outlay is still only about $400 to maybe $450. If you already have a drill, then it is half that. If you are on the lighter side, you may not even need such a large drill to power it.
