Splicing 5mm dyneema

[simonfraser]

I can splice the core & get two cores in the outer braid, but two cores and one braid inside is beyond my skill / power, yes I did taper them, the taper goes in no prob.

The outer braid just does not seem big enough .....

A job for the professionals or ?

I don't know what kind of splice you're doing but I've done eyesplices on thicker dyneema.

The technique is to get the cores one inside the other for 18 inches or so (on 8/10mm) and pull the outer braid over them. The other length of braid is cut to 3 inches or so and sewn on to the main line. You have to sew right through with twine anyway to prevent the splice from loosening up when lightly loaded.

It would help if you wrote what type of rope you are splicing (make/designation).

The short answer is it depends - on how loose the outer braid is. You have some alternatives.
1) unbraid the part you will burry and pull it in some threads at a time
2) unbraid and whip on the outside
3) make a "naked" eye

i recon 2 and 3 are the only option on such small rope.

but the rigger might know better, have e-mailed them.

Would be interesting to know what kind of rope it is.

Remember that some dynema ropes have an intermediate braid also.

this is the rope:

I did not find "5MM LIROS RACING REGATTA DYNEEMA BLUE MARKER" in the liros catalog but i found two with almost matching names
"Liros Racer" and "Liros Regatta 2000" both have "Aditional cover plait"

Ropes with this construction consists of three layers, the layer in the middle serves two functions.
1. Less dyneema with same diameter = cheaper rope
2. Increase splicability - remove this and you get more space inside the cover.

It's not easy to see this intermediate layer if you are not looking for it, tends to stick to the inside of the cover.

Tnx, shall have a close look at the cover(s) later & have another go.

Good point hooli, why am I fussing as it needs stitching anyway ......
