friction saver pulley?

does any one add a pulley too their friction saver and how do they add it?

I had one set-up that way, but the line load always seemed to be primarily on the carabiner (which seems to set a bit higher), and not the pulley. Also, it can be tricky to set those from the ground. I like the rings.
 
When I used to use a RING/pulley friction saver, the piece of rope had a big 'biner on one end as the big ring and I attached a slack tender pulley to the other end via a small quick-link.

Nowadays, I'd recommend directly splicing an ART block directly to the rope to bypass the other piece of hardware...assuming you didn't mind spending the bucks on the ART block.

Or just go straight to the top and get a rope guide. That's the road you're headed down. Might as well take a shortcut and go straight to the finish!

Here's one I did last year. This is from a rope guide, but you could visualize what it'd look like if the pulley was NEXT to the big ring...

I've tried that setup with the "Link 1" ART pulley and didn't like it. The cheek plates on that pulley aren't really any wider than the shiv itself. Consequently I found that when the pulley was pressed up against a ring or carabiner the shiv tended to rub on it. I also own the cocoon and have found that it works much better albeit a bit of a waste used in that configuration. I find that a simple micro pulley like a fixe is the easiest and best option. Sure you can't splice it on but at least the shiv on your $100 pulley won't get all scratched up.
 
I understand how the pulley will cut down on the bend radius in the rope, but is there any other benefit I am not seeing? I still imagine most of the friction on the krab or the snap I see in these pictures?
 
You can try a Petzl Fixe pulley instead of the regular CMI pulley. That's what I use and it works much better. With the CMI pulley I found that the biner was usually higher and caused the rope to bind on the cheek plates which created a lot of friction. But with the fixed side pulley, the top is open so its not an issue.

are you setting that up like treedimensional? if so does it get stuck alot when you try to remove it? can you set it from the ground? can you remove it from the ground? just picking your brain on your set up thanks.
 
I set it up exactly the same as treedimensional. I use a sling, two biners, and the fixed side pulley. It works just like the standard Buckingham ring & ring friction saver except that you can install it midline without threading the end of the rope through. The biner acts as the large ring and the pulley acts as the small ring. You can install and remove it from the ground. It comes out well enough from the ground as long as it was installed above a good open crotch. You can use a throwline to remove it so it doesn't come flying down from the top of the tree. I use a little screw link to catch on the pulley to bring it down.
 
Another way to save money on this set-up is to use your ring-to-ring FS and remove the small ring. Replace the ring with a carabiner and a micro-pulley.

I don't have a fixed side pulley, which might make things even more frictionless. Like mugs says, it is as easy or easier to install as a ring/ring FS, and is very simple to re-crotch up in the tree. Like Muggs I will use a throw line to avoid getting the FS getting stuck in tight crotched trees like Ash and Linden.

I have a rated sling in the middle, it is quite a bit more resistant to the wear, from bark, than a 1" web sling.

I think the link showed the RPO37 being rated at 22kN not 24.

The CMI glide pulley breaks at 7000lbs and wont slide over the gate of a biner. I have one in the gear bag that I've used as a floating anchor in a pinch.

What do you think, Norm?

Cory, as long as the biner can't rotate over the gate on the pulley, it should be fine. I personally don't have any experience using that specific pulley.

A climber with use of this pulley please chime in.

I have 2 ISC RP037's that are rated at 24kN.
 
I run a FS with the CMI micro pulley and a Petzle ball lock krab. I like it. It was the same price as the double ring ones when I bought it.
 
Decreased friction and slightly larger bend radius.

The disadvantages- more components in the FC. More hardware to hit the ground if you just let it fly. A bit more challenging to set from ground. Increased chance of operator error due to the opening and closing mechanisms.
 
yaaa im alright with ring to ring but i wouldnt mind giving it a try for the heck of it in a nice open crotch i can just tie a double fishermans on each end and put bieners and a pulley right like in the first attatchment?
