Secret Weapon question

This has been pretty darn slick for a secret weapon for myself. Just running with a 6 coil prussik.

Very sweet idea.

The bend radius on the eye-to-pulley ends looks a little extreme.

What's the cord material ?

Good observation Greg.
Climbing off a micro pulley is acceptable. The bend radius is extreme, but more than 1X the diameter of the rope.
I've been climbing off the Pinto Rig and it's niiiiccccceee.
 
Small ring on one end, big ring on the other. Retrieve just like it was a standard friction saver. He tied a Machard Tresse onto the parent line.

Norm I think he's talking about the bend radius of the eye splice to the pulley??

I'm pretty sure that Norm knew that I was concerned about the cord eye-to-pulley-plate attachement.

He was, I think, just addressing the small radius of the pulley, which also needs to be 1X+ the climbing rope diam.; which in this case it is.

Ciao for Now ! Greg
 
Norm, I love that ring & ring, very nice work. Tell me (us) some more about what appears to be "liquid electrical tape". I just bought some to experiment with and would greatly appreciate your experience and advice. ... and any other particulars about how you made that gem.

edit:
(If this is too big a derail, I'll delete it and ask in a new thread.)

Hi all, there are some great ideas going on there. After having a look and a think i came up with another tried it today and seems to work well and retrieves easily, whats anyones thoughts on it?

Hi Treesurfin,

Looks good except for one big problem - the slings you have there look like dyneema - very low melting point of 300 degrees and they begin to lose tensile quickly at only 150 degrees. Switch those out for nylon webbing or some other type of prussic cord with high temperature ratings.

Your getting the idea though.
 
Hey there, why would i need to swap out the slings when they do not move on the system once set? These slings are widely used on rope guides which are home built by many climbers, or from rope guides which are available to buy from shops.
 
It's a product called 'liquid tape' sold at Home Depot stores in NE Illinois. They have it in black, red, green and white.
I asked Samson Rope about applying it to arborist rope fibers and got the green lite to use it for that application (over the stitching). I just brush it on over the stitching to firm it up.
 
Treesurfin, the slings aren't like, bad bad or dangerous, they just aren't necessarily a good application for dyneema. Personally I would be more concerned about UV degradation than heat. I know of two of those slings (one Bluewater, one Mammut) that have failed unexpectedly under static load. The going theory is they spent too much time in the sun. I don't know how old they were but it was over a year. The failures were complete and sudden, they just broke.

It's just a theory theory though. I trust those things completely for rock climbing as long as they get retired after a year of active use. They're stupidly strong. I still have a few in use for speedlining limbs but I've switched to nylon on new ones. Better safe than sorry, plus it's a lot cheaper.

If it was me, I'd use Atlantic Braids 5/16" Tech Cord for the rope guide.
