What do you think: cambium saver?

[russelltree]

Please have a look at my attachment. Do you think my
cambium saver in this configuration is all right? I am asking
for thoughts/comments specifically on the way the stitched
splice interacts with the thimble loaded with a DdRT system.

Thanks, Russell.

I'll try to attach the photo again.

Thanks.

Haven't seen this friction saver before, the set up seems all right.
The loop woth thimble has to go trough the big eye and it will sure press on the stichted termination.

Only remark I have is that you use only one thimble to put your climbing line trough, the bend radius isn't great on this and you will have way more friction compared to the same setup with a pulley, but thats only my thoughts and you sure will have a reason for this type of friction saver setup.

the loading is all different, the main pressure is on the thimble, the friction and curve around the tree is holding you aswell as the spliced/sewn loop, cannot see what you have done to the join the loop, can you explain?

Rotate the line through the thimble, personally id rather be putting a pull on that stitch than side loading it directly at the termination.

Jeff- I think it's loaded that way so that the stitching keeps the eye open during retrieval.

 

[russelltree]

That's exactly it... It retrieves like a dream,
until it gets stuck of course. I also don't mind
slightly more friction than two rings, or in this case
two thimbles. I think the simplicity of it makes up for its lack of adjustability. Also, it can be adjusted if necessary by daisy chaining between the thimble and the stitch/splice. Do you think the loading across the stitch is too much? I also use it for an floating false crotch on single, or doubled rope and even for a foot loop while srt ascending.

Thanks for your comments/ideas.

Russell.

I don't like the load on the stitching. Seems easy enough to put some kind of shrink tube or wrap some tape to stiffen the bight for easy removal and position the sewn join away from the cross load.

I wouldn't be worried. A simple call to the manufactor would do the trick. But i don't see why loading across the stitching changes the strength.

 

[russelltree]

The stitch/splice is rated to 22kn, plus some, but I'm not sure if that's exclusively tested in-line or it can be across the stitch. I just had it made up because of how reliably it retrieves and because I like how little gear it requires. I also feel good about it being steel.

Thanks for your thoughts. It wouldn't be too difficult to add some tubing and rotate it to keep it off the stitch.

Thanks.

Is that the new 10mm DMM thimble?

 

[russelltree]

I think it's the 8mm thimble. But still very smooth to climb with IMO.
