Wed Aug 08, 18 12:57 pm Ride Engine slider rope - size? |
|
|
I've been buying bulk 1/4" Dyneema line locally but that's not really big enough. The replacement rope sold by RE seems to be about the same.
Anyone here using 3/8" Dyneema line? Not sure that would fit through the spreader bar hole - but fairly certain 5/16" will fit.
Seems to me bigger is better when using a slider rope!

1/4" 6mm 8,600 Tensile Strength (lbs.)
5/16" 8mm 13,700
3/8" 9mm 19,600

the hole is 5/16 wide.
i use the RE replacement sold by Windance for $5.00.
it lasts a 100+ sessions for me.
i 've never broken one - they start to get a little frayed after 100 sessions and i replace it. guessing it would last another 50 sessions if i did not replace.

But I don't know what size rope he was using - or the rope material.
Check out the difference in tensile strength I posted earlier - quite a boost in strength from 1/4" to 5/16" !!
Sure wish Windance & RE would provide the 5/16"/8mm size - but pretty sure that's not the case. Plz correct me if I'm wrong!!

I was shredding through my ropes (with a Dynabar). Especially when there was the quick release thing on one side. I got rid of it and now go with 2 ropes and 2 rings and keep them waxed. Much slower wear and tear now.

Those prices are kinda high. For example, I just bought a spool of 9/16" Amsteel blue (not for kiting!!!) at Englund Marine on the central coast for about $1500-1600 cheaper than this website.
If you are near a trusted purveyor of rigging such as Englund, just take your harness in the store and talk to the resident rigging guru. I guarantee you will learn something, and you'll probably walk out of there with a better slider rope than you had before...
By the way, I just made a Nak-style replacement slider rope for my dynabar out of doubled-up 1/8" amsteel blue, finished off with an oysterman's knot ala G-man. It looks sweet, but as the wind has been dead for the past 2 weeks, I haven't been able to test it out yet.

How is your doubled-up 1/8" rope a better solution than a single 5/16"/8mm 13,700 tensile strength (lbs.)?

Hi Unbob,
Here’s a pic of my Nak-style double-layer slider rope, uninstalled for ease of viewing.
Advantages as I see it:
It’s made from a scrap from building a replacement depower line.
I already have a bulk spool of 1/8” Amsteel blue.
Double-layer ropes wear better than hollow braid. You are essentially making a kernmantel rope when you double-splice. This prevents the rope from squishing flat under load, and a round rope fits the groove in the sheave of my dynabar hook really well.
The eyesplice allows me to secure one end with a shackle, which means I only have to tie one knot—less opportunity to slip and add slack to the system.
Re: tensile strengths, I think there’s a natural tendency to overthink things. We are kiting, not making dynamic crane picks... The line in the photo should part at about 5K lbs., but since we’re pulling on a bight on a slider rope you effectively halve any load on it. Unless I gain a lot of weight, I think 5K lbs is plenty! What’s the tensile strength of your kite lines?
Ultimately, there are a gazillion ways to skin this cat. Whatever folks decide to do, make sure to inspect your gear often...

I got to test it, finally...
It worked great. Minimal stretch, plus it slid much more smoothly thru my dynabar hook’s sheave than the old piece of 1/4” or 5/16” hollow braid I had been using. No visible wear...
Happy rigging to all.
