Rope thimble question

[Ace76]

What is the best way to secure a rope around a thimble? This particlular rope (static kernmantle) isn't splicable, so I was thinking either rope clamps or stiching.

[NickfromWI]

What thimble? Can you post a link or pic? There are quite a few types and each might be treated a little differently.

If this is for a climbing application I think you should go with a knot. Unless you have access to an industrial rope-terminating sewing machine (like the Grizzly stitch sherril does), there isn't a way to know the strength.

What's the application here?

Make sure that thimble doesn't have any sharp edges. A plastic thimble won't work? Or what about something like

this is not going to be for life support. I am making a swing in my backyard and I want to use the thimble to keep friction from wearing through the rope.

They wont do rope that has already left the factory, and I'm not buying a new rope just for a swing.

Where are you located?

[Mr. Sir]

Why not a knot? Is a knot not the most efficient way? I think, knot! :/:

[Ace76]

Where are you located?

North Georgia close to TN. Why?

[NickfromWI]

How about NOT going with the rope you talked about. What about a stout double-braid polyester with the thimbles I suggested.

[Ace76]

Well, that would be an option if I knew how to splice and if I didn't already have so much of this static kenrmantle laying around.

Thanks for the idea anyways.

I may just use a scaffold knot

or hand stich and whip.

I like option 2 if you can do it in a way that you feel comfortable with strength wise.

I would avoid the scaffold hitch because it is a cinching knot that by it's very nature will pull the knot into the sharp points of the thimble.

What about no thimble? Is that an option? Just clip it to a biner!

The only reason I'm considering the thimble is to prevent the friction of swinging from damaging the rope. If the friction isn't an issue I may just attach a scaffold hitch straight to the eye bolts.

[MasterBlaster]

Definitely a good thing to do, IMO.

The thimble or attaching straight to the eye bolt?

[NickfromWI]

Run the eye part of the rope through a piece of tubular webbing (or two) for chafe protection then tie straight to eye bolt. Inspect and replace webbing as needed. No thimble, no 'biner needed!

The thimble?

If option 2 is the second pic. I cant say I would trust it in a load, unload situation that a swing could place on a rope.
Now if the end was tucked back into the standing part of the line & lock stitched then whipped as shown maybe.

[NickfromWI]

A proper seizing can be as strong as a splice and way stronger than a knot. I think this is a good app for that. It shouldn't be exposed to things that might try to cut the seizing

If I were doing it, I'd leather the eye, too.

Why not a cinching knot straight to the eye bolts? Would they move around any?

If so, why not knot a biner to the end of the rope, puts the friction on the biner instead of the rope.

[NickfromWI]

I'd be cool with tying straight to the eye bolts. Makes sense to me. Inspect for chafe occasionally.

Or even put a piece of tubing over the bend.

Seems awfully simple to me :)

I'm not understanding how an eye bolt is going to wear on the rope in the first place. Isn't it about the same as how we tie into a carabiner? I've had spliced eyes on ropes that have been through tons of use and I've never seen a rope yet that was worn to the point of weakness at the eye. In my earlier years I kept a locking snap tied to my lifeline for years, and when I finally retired the rope the spot where it was tied was a bit brown from rust but not worn.
