Top, I did show my upgraded version of Tobe Sherrill's so called Tree Frog SRT system. I have replaced the footstrap with an adjustable one, and replaced the single left hand CMI Expedition ascender with the new CMI Expedition two handed ascender.
It's a pretty good system, though I think my...
It did when tested by just setting down on it Frans. I grabbed a footlock, eased up with the ascender, released off both cams and sat down on the hitch. But as I said, that's different than the situation of losing one cam. And it's only one test on one rope/hitch combination...we all know the...
If one cam fails, I will fall away from the klemheist hitch, taking the ascender with me, assuming the backup tether has some slack in it. The gap/spread between the lines would disappear within a few inches of movement downward, wouldn't it?
The line I set was not long, Pete, only about 35 feet to a convenient limb to dismount onto. Over that distance, the klemheist seemed keep dressed and to grip fine if you settled down onto it, but that's not the same as losing grip on one cam of the ascender, so I can't say for certain. I...
Chasing good climbing weather, brother. Last year we met in Boise, and it was cold and snowy. Year before that was in Portland, OR; rained like to choke a frog...we decided never again.
We have to meet in the early spring so the members of our group who are Smokejumpers are available, before...
Well, I just read that article...and Mark (whom I have a lot of respect for) does not address the setup I pictured at all. I don't know why. He suggests a system similar to the one I pictured, but without the tether from the Kong ascender to the climber. So his objections may be valid for his...
I recall a bunch of discussion and back-up knot invention on this subject, too. Truth of the matter, I'm afraid I dismissed the whole discussion as over-the-top back-up mania, but perhaps that's unfair and incorrect.
Was Nick involved with describing some sort of double prusik?
No sir, not to my knowlege. Please educate me.
Only thing I see is that the Klemheist is not dressed properly yet...but I'm new to the double line ascenders, so speak up, I'd appreciate any input.
OK, OK...acronyms suck :). U.S. Forest Service National Tree Climbing Program Technical Advisory Group. What an effing mouthful :lol:.
I am a member, representing the Pacific Northwest region. This is a small group of regional program coordinators and technical advisors who set policy for...
