sta-set-x

[svgusto]

Is it possible to splice sta-set-x to wire for my halyards? I got the line and then realized the strength is in the core, not the cover. Is there a way to splice it to wire and still maintain strength?

[Stumble]

I would assume there is a way to splice it but I outsource all my wire splicing. The better question is why are you using wire as a halyard? It is heavy, expensive, and the strength of it is no longer competative with modern synthetics. You may just want to look at replacing the wire halyard with line, or cored line if you are weight conscience.

Thanks for the reply. The boat is a 1967 Tartan 27 and is set up for wire to rope. The wire is 1/8" 1x19. so sheeves are not made wide enough for rope. Replacing the sheeves is cost prohibitive at this time. I have found no info on sta-set-x to wire splicing.

for that boat using 1/4" dyneema core line should be fine, 5/16" if you please. you can either slide extra cover on it to bulk for handling or just tough up a bit!

strip the cover of the 1/4" and it will fit the sheaves fine.

why use sta set X for a wire halyard tail. normally something cheap and low tech is used as the wire is meant to be the load bearer and low stretch.

that said the splice shoudl be the same. bundle the core strands to 3, tuck away, run the cover past and bundle to 3 , tuck again. where you have to unlay the guaze to bury the wire tail, just do your best to wrap it up again over the core strands and wrap all with marlow tape.

I have to agree with this.
I have never sold a rope/wire halyard made with StaSetX but I did experiment once. I believe that you could make a strong splice but you would probably play hell trying to make it pretty.

I may be wrong, but 1X19 is not for halyards. It is relatively ridgid and used mostly for stays. If you are trying to bend this around a shiv, you are likely going to see premature breaking due to bending it so tightly. 7X19 is normally used for halyards because it is much more flexible.

Either way the breaking strength of 1X19 wire or 7X19 is 2100 or 1780 lbs respectively for 1/8 inch wire. While 4mm (slightly smaller than 1/8) V-12 has a breaking strength of 3500 lbs. So theoretically to get the same holding power you could go down to 3mm with a breaking stength of 1900lbs. Of course line this small would be very difficult to work with, but then just put a larger core over part of the V12 and you get a stronger halyard, eliminate weight, eliminate the possibility of meat hooks gashing someone, and the whole thing will likely cost less than wire.

In other words, I would recommend against wire, and go to high tensil line.

i think the guy meant 7x19.

v12 is great line but its low UV resistance maskes me shy from recommending it as a halyard line.

that is why we use covered lines. 1/4" endura braid (since we are talking in NERopes names here) is about the same as 1/8" wire in strength.

the guy is right, consider going to hi-tech line if your sheaves are really an issue. rarely is there a problem running line through sheave boxes, but make sure the wires have not filed sharp burrs on the metal up there. new sheaves from Zephyrwerks.com are only about $25 for boats that size...

Hmm, well I do take slightly extreme steps to minimize the UV impact on my V12 halyards, so it may not be the best answer for everyone. I have a ring that all my halyards attach too that is run to the top of the mast after sailing, with a tag line to bring it down. So all of the line is protected in the mast, then the other end is covered by a sailcover that runs pretty far up the mast.

But there are some very high stength lines that should work with your shives, and in my experience getting rid of wire whenever possible is a good thing.

I appreciate all of the information. Have contacted Zephyrwerks in reference to new sheaves. I did not realize sheaves could be had for a reasonable price and I have an idea my wife will appreciate a larger line. Thank you for the help.

make sure to tell Ed we sent you from here, maybe there is a spartalk discount ?
