I got some 1/2" steel-thimbles for my climbing-rope but sadly I'm not sure how to safely use them, I'd thought "I can just tie a knot at just the right spot so that the thimble is securely nested in the end-of-line loop" but, having since learned about knots & knot-failures (stuff like capsizing a knot), I'm now unable to use these thimbles because I'm unsure how to safely do so and if one failed it could be disastrous (maybe you're not even supposed to use these as part of any lifeline? Doubting that but not sure!)
Here's a link to the specific product, I got the 1/2" ones to go with my 11.7mm Blue Moon rope, with the intention of using (2) of them on either end of a 6' section I'm going to cut-off of my climbing line (to make into a general-purpose sling/lanyard), and using one knotted to the end of my climbing line so that, when rigging a basal anchor with a running bolan (or whatever knot is best here), the rope-on-rope friction would be eliminated as well as the start of the standing-leg of rope takes a very sharply-angled bend and this is blunted a bit by the thimble as well :D
Thanks a ton for any advice on using these, I got them both to keep my rope's integrity up there for longer, as well as to have a stronger climbing-system once I've rigged everything up and my "weak points" have these steel thimbles at the contact points instead of rope-on-rope!
I'm pretty confident that I need to stay-away from using any cinching-knots here because when under-load they'd want to 'squeeze-off' the thimble, but so far as I can see I should be OK to use them if the knotting is 'fixed' and doesn't cinch-down, just unsure what to do and can't use them til I know for sure of course!
Again thank you so much for any advice on this one!!
