Splicing Cruising Dyneema

[olly_love]

i have got a few rolls of cruising dyneema sheet that im changing to use for my haylards, now i need to put a covered loop in the end or splice it somehow,
i tryed to do a standard splice but the cover is to densly woven, does anyone have any good ideas, i was thinking of tapering the last meter and then splicing a loop in that but it may start to fray and uv degrade

Is it braided core dyneema?
Can you splice the core and cover it with the outer taken from another bit of rope?

i use a buntline hitch

i could do however my kite halyard and jib halyards are very close so any knots would jam against eachother in light airs

The very best way to learn anything is through being taught, one on one, by a young and pretty girl.

The second best way is to search on YouTube for the many videos which show exactly the right way, for each of the many types of rope - and certainly your Dyneema.

Cut back the cover, and do a mobius brummel splice. Then you can cow hitch your snapshackles on. A bit of googling will show you how to do this. a good set of fids a great help.

You may well have bought the cruising Dynema from the same guy that I did, and yes its almost impossible to do the proper splice because of the very tight cover. I was impatient so I did the splices myself , doing the inner core as per the manual but only managing to get half the recommended amount of cover back into the standing part even after a lot of huffing, puffing and belting it with a wooden mallet. . So I then stitched the splice and whipped it. And that was using the proper fids.

I have no worries about the strength of the splice - the load on a halyard is way less than the breaking strain of the rope - you are only using Dynema for its low stretch not its strength.

The guy who sold me the rope insisted that he could do the splices properly and was willing to do so at £1 per time. Had I been less impatient I would have taken him up on his offer

Old rope??

I had a splice done for me yesterday..

Very pleasant chap at Rice and Cole... He said that it is usually very difficult to splice older ropes as they tend to have too much friction in them for the fid to slide inside the core....

Indeed I have found this to be the case and have not managed to splice older ropes... It is also impossible to splice if they have been strained...

I do not put splices in halyards as they take up too much length if it is necessary to move a wearing point... Just use a simple knot at the top shackle and whipp a loop on the end if you want to mouse ...

X2 i jus tuse a bowline at the end of the halyard for jibs and spin. Every time I bend on the sail I try to use a different length tail on the bowline to vary the wear points. olewill

Not a good idea to do brummel splice on crusing dyneema as half of the core is polyester and is not as chaffe or UV resistant as the dyneema.

Also you shouldn't do a braid splice as this strongly relies on the strength of the cover which is not as strong as the core.

There is a proper dyneema cover on splice, I do the liros one which is pretty easy (although a lot of steps and measuring) the 32 plait cover is always a bit tricky but I have never had a problem splicing it and I have done hundreds of times on many different makes.

Perhaps it would be useful to splice a metre of 12 strand braided dyneema on the end and splice the eye in that?
