End to end splice
 

Is there a way to splice end to end spectra 6mm to pre-stretched polyester 8mm for halyards?

Possible
 

Hello,
Sure, it can be done. But what is the application? Our most common configuration involves splicing the Spectra to the Dacron core, using a Brummel like the one for HM grommets (see Splicing handbook), and then burying a long tail. The length of the tail will vary with application. Another form involves a different configuration in Regatta Braid. So, more info please.
Fair leads,

Thanks Brion
I am replacing the wire/rope jib and main halyards for rope/rope. The mast cap sheaves are limited top 6mm wire or rope and the halyard winches will take 8-10mm.
I intended to use spectra at the mast and a larger diameter rope at the handling end.
I wanted to splice the 6mm spectra (to go through the cap sheaves) end to end to 8 plait pre stretched polyester (for the halyard winches).
I found some instructions on the web but all were for same rope type and same diameter.
i.e. http://www.sailingservices.com/runni...df_end_spl.htm.
The boat is a 28' GRP masthead sloop of 3.5 ton.
