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.

The boat is a 28' GRP masthead sloop of 3.5 ton.
