Have Rope Will Travel 3 Years, 9 Months ago  
Treetramp this is the kind of fun stuff that keeps me comming back to post. That's exactly the info that i wanted to hear. The rope is made by New England Ropes, Maxim Climbing Rope, Static, KMIII, 7/16 Diameter and 150 long instead of 120.

I am looking forward to the replies from Nick from WI, he will probably suggest to splice it into little pieces !!
I like your idea for the spider legs for the treetamp. Have you run into BJ since the NE rendezvous? I Have some pictures of her in your treetramp. I saw some of your posting in another site in which Dick Flowers has a lot of stuff about trees Identification. It is amazing the people you run into on these web sites. Most of the postings from Michigan are from 2000 and 2001 were pretty educational and interesting.
Take care and climb safetly.!

splice? 3 Years, 9 Months ago  
I am almost sure that your kind of rope is not splicable; (is that a word?)

I like the pretty colors that the use to braid it but bending knots is tuff.

BJ sent me some artwork and am sure she would like to see your photos; can you post them or email them?

Bill McMillian took some and posted them at our website at: KCTC photos


See you at the top,
Dan

Kernmantle rope can be spliced from what I understand. Nick will expand on the subject I'm sure. From what I understand the splice isn't really workable like we consider other eye splices.

KMIII is wonderful rope. That is what I've used for years as access line. When I climb/work on SRT KMIII is my rope of choice. Right now I'm working on finding a hitch that will slide and release like we expcect when climbing DdRT.

KMIII 3 Years, 9 Months ago  
I love the stuff. Works well with ascenders, and descenders. Is a perfect rope for SRT. DRT prolly not such a good idea. I've been known to use a 30' lenght for a double ended rig, to use when "ladder climbing". Falling on static line would not be pretty, but I think (and you guys correct me if I'm wrong) that if it was set up as a DEDA rig the fall lenght would be limited, and you might be ok.

Maybe keep the rope. I keep a lenght of static line to use for traverses too.

Climb Safe!

iI've been using static line for lanyards for a long time. There is so little line in the system that any fall onto a lanyard would hardly generate enough force to factor in line stretch.

If you understand how stretch is calculated you'll see that most arbo ropes are pretty close to being static lines. The stats are close.

That stat is _base_d on the amount of stretch at a percentage of the breaking strength. That catch is that there is no standard way to measure this number. When I first started to learn about rope construction I had the opportunity to spend close to an hour talking with Dick Hildebrand about the stretch measurement.

If you took a brand new rope off the weaving machine you would find that the rope has lots of stretch. After climbing on the rope the fibers would be pulled into linear alignment. Instead of being coiled so to speak, they'd be pulled out. The used rope would stretch "less". What Dick told me they did was to take a rope, put a load on it and hold for a length of time. Then the load would be removed and the rope would recover. This would be repeated, bringing the load up over seveal cycles. When they go to the load they wanted, they measured the amount of stretch.

Stretch is _base_d on a percentage of rope. So, if there were 100' of rope and there was a load of X on it, the rope might stretch three feet. That would give a 3% stretch at that load. Now, take the same rope and make a lanyard. The lanyard is 15' long. Apply the same load and how much would the rope stretch? about 5.4" But...how could a climber fall far enough to even generate a large load if they're using a lanyard?

On my rec saddles I use a 3/8" static line.
