Pulley Rub on friction saver

[Sizzle-Chest]

okay, so i made that adjustable friction saver with the pulley and all. but i think im using it wrong because the side of the pulley is starting to wear down. If you look the first picture, you can see how it might look up in a tree, and how the metal pieces rub against each other. In the second picture there is an arrow to show where the pulley is getting ground down. Can i get some advice on how to not have this happen, or is it normal. I tried adjusting the friction saver really small so that they wouldnt connect but they always manage to make contact. THanks for any help!

See Sizzle,

This is what happens when you mix alloy with steel in your system.

Now if both were the same you'd have a lot less of that wear going on.

Now, those small pulleys are rarely steel, so how about changing the screw link to say an alloy carabiner.

Sizzle, have you tried the "Adjustable False Crotch" (page 50 "The Tree Climber's Companion)? I really like it. Gets the pulley in the system for friction relief and seems to combine the benefits of SRT and DRT, and nothing to erode the pulley. And, a skilled groundy can lower me back down if I get in trouble. It does put another rope at chain saw risk, but I mitigate this by tying my anchor line to another tree at a pretty good distance from the one I am climbing. That usually puts it far enough from the trunk I am working on to get it out of harms way.

Until you drop something on that line and head for the moon.

I dont have the TCC in front of me but I believe its a pulley on the end of a second rope anchored at the ground?

Drop something on it and you get a bump, but it can't pull you very far very easily. The knot and pulley would have to be pulled all the way through the crotch, with your full weight on it, to be much of a ride. I don't use the system topping, so it would have to be a very big limb seriously hung in the anchor line to give you any more than a bump.

I use the system mostly to gain access to the canopy, and to work on smaller limbs. If I need to top something out, I'll use the friction saver Sizzle is using; the "Adjustable False Crotch" is just easier to set from the ground.

hey fireman, heres a better picture of the whole thing. as you can see, its a differnt type of adjustable FC, but thanks for the advice because I was wondering if there were other ways to do it!

Hey Sizzle, like Mr Tom said, change out that 8 to a barrel knot (tripple overhand) or a similar knot.

Have ya done it?

Sizzle,

Put a proper stopper on that, not a figure eight. Eights have been known to work themselves loose.

Why don't you use an HMS biner instead of the ring? When you did your research of the past discussions of FCs you MUST have read about the advantages of using the big biner.

tom, put your mind at rest, that was an old picture, since then i have put in the double overhand as you suggested, a stronger pully and instead of the small ring you will be happy to know that i have a new aluminum biner so that the hole is bigger and the metals are the same. i will climb with it tommorow and let yall know if that does the trick. thanks!

Good to hear!
