Increasing double braid diameter
 

Hi to all.
Sorry for my english, I'm italian and what you're reading is my very best :-(

I'm trying to modify the halyards of a boat as to loose wait on the mast.

I've seen a great solution on a french boat I really don't know how to make.
The mainsail halyard was a vectran core with a polyester cover. The cover has been removed for the most of the lenght (I know to splice this) but, due to lower diameter of the halyard, even with the cover in place, the stopper didn't worked properly and, sometimes, it slipped a bit if under load. To solve this, over the original cover, has been 'spliced' another cover. To be sure to be understandable the result is: a vectran core, a polyester cover, another cover on it so, a core and two covers.
The result was perfect to use (and olso to see).. there should be any 'trick' to bury the additional cover. in the place where the two covers were locking together there was an additional whipping but seemed not really needed as the spare halyard didn't have the whipping.

I tried to find this sort of splice on google but without any result... maybe because I neither know the name of such a work.
Anyone can help me?
(As my english is poor.. pictures or other 'stupid proof things' are very welcome)

Thanks.

Anyone knows how to get that result?
Any picture or documets would be appreciated (as my english is poor..)

Thanks a lot.

Alberto,

What you are talking about is a tapered splice, which is becoming more and more common among racers and other high tech purchasers. Both to save money and to reduce weight.

I am sure someone here can give you instructions on how to do this type of works, and I would assume Brion's books, videos and tutorials would cover them in depth. But a quick down and dirty example can be found here http://www.neropes.com/SPL_DoubleHitechTaper.aspx

Thank you.
Anyway I fear this is not what I'm looking for.. my bad english, I think, does not help.
I use the Tapered Splice if I want to remove the cover from a double braided rope. But what if I want to add another cover over the existing one?

Did you mean I simply have to put the new cover on and than apply a Tapered splice to bury the new cover both inside the original cover and the core?
I've never tried but I've been told, in case, this will not work as suddenly the new cover tend to move from its position.

Where I do a mistake?
Thank you again.

Line Bulk up?
 

I think Alberto wants to take a stripped or tapered halyard and bulk up the portion of the tail that is belayed in the clutch.

He is suggesting that he wants to add a second layer of cover in the area of the clutch, and asking how.

I would suggest that a better solution would be to bulk up the line in that area by fattening up the core, thus increasing the diameter of the whole rope.

I would extract a length of core, insert some material in the core, and pull it back into the cover.

Anyone have detailed instructions on this?

Bob

Thanks Bob. You got the problem.
I've already thought at what your're saying but, in search for the 'perfect solution', I've abandoned the idea of inserting something in the original core. Fatting the core would create tension inside the cover (not built for a fatter core) and the resulting rope would be rigid and difficult to handle. The same result you get in the part of the rope near to an eye splice.
On the contrary, if it would be possible to add a second cover, as this second cover has been braided with a larger diameter, I expect there will be lover tension inside and the rope will be more flexible and easy to handle or to be used on a wich easily.

Anyway, if there is no better solution, I'll exactly what you said. In my own picture I have to put inside the core a second core (about 2mm in diameter) taken from another rope. To get everything in place I supposed to sew the 'double core' with a sail needle. Nothing more.

Thank you again.

Alberto,
Did you ever find a solution? I want to increase the end of my double braided poly stay sail furling line to make it easier to handle.
