My friction saving false crotch what not. . .

[Sizzle-Chest]

okay, im sure you'll all laugh at me, but here is my new friction saving what not. i didnt put in a pulley cuz too much money. I didnt use carabiners cuz too much money. I bought some rope, a screw link and a ring, all rated real high. Its sort of a combo of the adjustable deal combined with the double ring friction saver. Please tell me if you see problems with my setup before I use it, of course I will test it out on the ground, but if you see anything i should change, SPEAK!!!

ps, thems double-fisherman loops holding the rings, what do you think?

Is that rope......tree pro red and true blue 12 strand?

 

[notahacker]

Double fisherman's are fine. They are self tightening knots.

 

[Sizzle-Chest]

actually, its buzzzzzz or some stupid name like that. the picture makes it look red but its high-viz orange, 12 strand. And the other, yes, is true blue 12 strand.

but what about my setup in general?

 

[Davidsinatree]

Also I would not trust that set up. The ring does not look like its load rated and that is not a good aplication for a screw link. The small dia of the link and ring will create friction on your rope. Rope will not slide over them smoothly.
Is saving $25 for a friction saver worth chancing getting hurt?

yes . . . i mean no . . . well that ring is rated at 2500 lbs working load, and last time i checked I weighed a little less than that. but i was also concerned that that screw link would cause a problem. i was thinking about maybe. . . just maybe putting in some money for a pulley that I could put on the end of that screw link. but that ring is plenty big enough for the rope to slide over. Either way, your talking much less friction than i have right now sliding over tree bark.

Your set up will still work.

Buzzzline, made by Yale, a 12 strand climbing line.

Looks good, a bit bulky, but it'll surely do the job. Splice that up and it'll look top notch!

thanks Nick, i would love to have that spliced (or know how) but i dont have the money, hence the ackward setup. I think i will look into learning how to splice, seems like it has infinate applications to rope, but i thought I heard a person cant splice 12 strand. True or false? I saw a old post from you about splicing, can you recommend any particular books that are good for a beginner?

Sizzle, the screwlink isn't unsafe-if you tighten it with a wrench the rope won't unscrew it BUT, as David mentioned the bend radius is very small-which is very bad for your rope. You can buy load rated Aluminium rings from Sherrill. Karl Kuemmerling has steel ones. They cost less than 'biners and pulleys. I understand about being brok-been there frequently but if you can't afford a few bucks for the Big Shot and a couple of rings perhaps you can't afford to keep climbing for the non-pay you aren't receiving. :angel:

well, the plan is that if i keep climbing then i can start making the money for climbing. right now, i be only groundy

any advice on making the radius wider? could i simply adjust the setup to be smaller and therefore the rings would not touch?

This makes me wonder about mine. It is also homemade. I use a cable with two ends folded back to make a loop on each end. I put one loop in the other loop which makes a slipknot allowing a very tight squeeze on the tree I then put a clevis on the tail loop. The clevis pin spins freely which acts as a pulley. I will try to take pictures tomorrow.

Please post a pic, this setup sounds rather bizarre and a bit scary. Is it retrievable?

 

[Sizzle-Chest]

found this pulley for real cheap, 11$, what do you think?

Hello Sizzle chest.
I dont mean to sound like a jerk but man I feel your life is worth the extra money. If you have to ask the questions here then maybe you shouldnt be climbing with a homemade rig like that. Looks real scary and very uncomfortable. I dont climb like most of these guys but I do rappel (recreation) and climb telephone poles for a living. Diffrent gear there but still I know what its like to come down hard. I have had three knee surgeries from my first and last accident (8 years working) and I had top gear just bad luck. I'm not downing you but if you get hurt then where would you be?

 

[Sizzle-Chest]

i dunno, i tried to make it safe. nothing is rated under 2000lbs, nothing can accidently open up, strong knots, i'm pretty sure this is what people usually use only with a pulley on the tail. I guess i will test it low to the ground and maybe snap some pictures for better idea how it would work.

 

[Stumper]

Sizzle, The Oscillante isn't a bad little pully BUT. While at 16kn ( a bit over 3500 lbs) it is amply strong enough to hold you, it falls short of the ANSI standard for life supporting gear (5000 lb tensile). CMI makes a little pulley that is rated at 5K lbs that costs $10. REI stores frequently sell them. REI also has one that looks like the CMI that is branded for REI that is Rated at 20 KN-which is still short of the required 5k by about 10%.

PTS, Your rig does not sound good. FWIW, if you have a SAFE clevis/oval 'biner/screw link, Petzl makes a plastic sheave(same one as is on the Oscillante) that sells for 3 bucks and will turn the hardware into a pulley. Hardware has to have the right shape and dimensions.

 

[Sizzle-Chest]

Ya, stumper, i agree with you. i wouldnt risk using that pulley to save 9$, i would just buy that micropulley. But do you think putting in a pulley would change the radius enough to 'make the difference'? Thats only gunna add like an inch or so, at the most. Maybe thats all it needs?

 

[Stumper]

The rope manufacturers specifically recommend an 8/1 radius for sheaves. That would mean a 4 inch diameter sheave for your 1/2 inch line. Those specs are to maintain something like 90% or greater of the ropes rated strength. You can wrap a 1/2 inch line over 'biner stock and keep about half the rated strength-which is still safe with strong ropes. The problem is that if you RUN the ropes over such tight radii they wear much faster. Even a one inch sheave is MUCH kinder to the rope-It not only changes the bend radiusto ease internal friction but also eliminates most of the external friction.

I think that you have done OK with that cambium saver you have made.

But as soon as you make a few bucks get the real deal.

Did you know of the ART Rope Guide? Here's a pic. Darn good device this one.
