Speed lining equipment and suppliers, give your best techniques.

[TreeJunkie]

I'm trying to get the boss man to buy us a nice long static line for speed lining. I'm thinking I'd like a 300 foot, 1/2'' KM111, Is this a good choice? Economical suggestions? I'm looking to find a good price on this, if the price is too high, i'm not really sure he'll go for it. You know being this isn't one of those items you are gonna whip out every day.
Other that the rope i'm looking to upgrade from what we're currently using. I thinking the Petzl tandem pulley which i think goes for around 39, as well as a the Petzl Rigger plate. This should be a nice combo i think. I figure these could be either connected w/ a couple of biners or maybe a couple of s.s. bow shackles, this might be a little more compact.

Does anyone have any photos of their speedline kit? Any suggestions of good hardwear/suppliers? Any great tips out there to making speedling a more successful activity.

I did a removal yesterday where i speedlined a few branches out over the house. We used a Grcs at the base of the tree being removed, and a porty at the tree in the front. We were using the CMI pulley, which has both a bottom and top attachmement, this was being used on the speed line, which i was using 11mm Km111, which had to be attached to a 120' highvee b/c the 150' km111 wasn't long enough. Any way, there was a total of 270' of rope being used total. I'm looking to work out a few flaws in this system, b/c i saw a few things that didn't go as well as they might should have.

I'm gonna resize a pic and then post.

Here is a pic, but PLEASE FRANS DON'T HIT THIS IT'S LARGE, i'm still trying to figure how to shrink the size...

Warning this pick is not dial up friendly.

I just bought 300' of 7/16" Endura braid from
Charli Pottorff (in your state!).
This stuff is totally strong, holds knots well and seems to be tight enough to not pick easily.
All in all I really like it just pulling it out of the box. soon I will use it and know more.

Thanks Frans.
I'm familiar w/ Charli, i order quite a bit of gear from him. Let me know how this rope works out for you. Do you remember how much the endura braid was? I'm looking for something w/ minimal stretch.

Rb,,, I know you can tell me what i need, where can i get it?

A high modulus low stretch line, the Endura braid is near zero stretch. KM111 has a lot more stretch than polyester double braid or arbo climb lines, at least based on data sheets that I've read.
So our normal work lines are really not that bad for speed lining. I have used the high tech lines, they're the best, but only if you're limiting shock loading.

My Puget Sound Ropes' DSComposite is similar to Endura braid, likely cheaper but not quite as strong. I only have it in 9/16th, but 7/16 would be plenty strong for most speed line applications.

I think the 7/16" Endura is 14,000 lbs. Man your 9/16" must be over the top. Strong enough to hold Godzilla!

It's rated at 18,800 lb, but that's minimum break strength, not peak as is likely the NER figure. Still plenty strong to pull over these badboy back leaners:

Thanks to my great supplier, I only spent $1.07 per foot, I'd guess your Endura braid cost about that?

I climb on KMIII and love it. Contrary to the specs that Roger is reading, I find it very stable. Arbo rope is WAY more elastic.

I would never use the KMIII for anything but a pretty lightweight speedline. Not strong enough combined with more stretch than the high tech lines.

When you read spec sheets you need to know how they come up with a number for the stretch.

Is it based on a percentage of the breaking strength?
Is it based on actual loads on the rope? How were those loads applied?

I spent close to an hour talking with, dang, his name escapes me right now, anyway from Yale ropes at TCI one year. All we talked about was stretch. There is no industry standard for setting the stretch percentage to allow us to compare ropes between manufacturers.

I checked the price on 7/16 endura braid, however it seems a little pricey. Sailnet is charging $2.86 per foot. Wow! Hmmm would 7/16 stable braid be fairly suitable?
