[atree]

Haha sweet,Keep it for you keys(the becket is rated you know)

[Liam88]

Absolutely gutted for you bro.

 

Thank you for the pics - you can really see the wear on the side of the wheel from the shackle.

 

Has anyone an idea of how to limited this damage?

 

A cheap pulley (micro pulley?) infront of the retrieval shackle? Or even just a cheap pulley as the retrieval device?

 

Plastic retrieval shackle? Can get them from any sailing shop of chandlers.

 

Cheers

yeah was pretty gutting aye bro, not sure if its from the retrieval shackle though. I think Drew has had the same problem. Rich from Tree Tools is looking into it for the moment hope he has some luck as to why this is happening.

[DrewB]

yep its happened to mine too bro-no idea why but mines just cosmetic damage as far as i can tell. its definetly not the shackle but something has been scraping the side like yours-bit of a mystery but im sure it will get sorted by the powers that be

[CraigD]

Haha yeah lets hope! I can't use mine anymore, it has a really bad grinding noise like the bearing has collapsed, when i hang on it and descend or ascend I can feel something grinding not to good, let me know if you find out whats up with it

From playing around with my ropeguide it seems to me that when you have the prussik attached individually to each side of the pulley, then when you move to the left the right leg takes more tension and vice versa. This doesn't appear to be a problem when you have the rope looped through the two eyes with a spacer. I think this uneven loading may be causing the sheave to rub on the cheek and cause the wear people are getting.

 

 

If anyone on here knows of any pinto's that have this wear on the side of the sheave and have it set up with a loop and spacer then I will stand corrected. It wouldn't be the first time:biggrin:

Are the spacers available anywhere as an individual part yet? I don't want to hurt the shiny lol

Great observation. It has to be another metallic object to cause that wear - rope, twigs, leaves etc wouldn't touch a hot forged pulley! So if it isn't the retrieval shackle then it could be from the pulley itself (on self destruct mode!)

 

This issue is probably why the pulley saver has a spacer.
