Lock stitching

[Ledburyjosh]

Hi.

 

I've spliced some trex onto a ring, following samsons 12 braid instructions for a straight bury.

 

When it comes to lock stitching should this be pulled tight?

 

Thanks

Why did you go for a straight bury over a locking brummel?

so I can start the lock stitching about 50mm down from the throat. that way I can open the eye up slightly to get the ring in and out to move it onto shorter bits of rope

Good idea to be able to remove the ring!

I wouldn't be happy with that tbh. There's a chance that under low cyclic loading it could just pull the splice out. Certainly wouldn't give that a loler pass. 

 

For lock stitching, Teufelberger have loads of material available online for splicing. They detail their recommended stitch pattern for TRex.

Is that not what the lock stitching prevents?

Yeah, with it’s intended use I’d feel like it was putting a little too much faith in the stitching though. You could do a straight bury, out for a locking brummel before going into the full bury perhaps. It would be a bit odd, but the locking brummel would be solid, and you’d still be able to milk a little slack into the eye to pop your ring out. That *might* work, but I’ve never seen it done or tested so no idea really…

The locked Brummell isn’t needed with a full bury splice, it would only weaken it some and not add any security.  The stitches are only so the bury can’t be pulled out when not loaded, they are also needed for a locked Brummell and bury splice.  Locked brummells are useful when a shorter bury is desired, like for hitch cords.

I have a few double braid splices I need to lock stich/whip.

 

My first question is what size/diameter whipping twine should I buy for use on 8-13mm cord and climbing rope?

HB list 1.5mm waxed twine. Its fairly expensive for 20 meters. 1.5mm seems a bit thick?

 

Seen a few instructions and videos, I am not too convinced by the lock stitch method, the whipped stitching seems like it would be more secure. What do you use?
