constant diameter 12 strand end for end splice

[allene]

Has anyone done and tested a constant diameter end for end splice in 12 strand? I did a quick test by removing half the strands and doing the splice in what was basically 6 strand and it looks promising. I am sure a longer taper would make it look better so it wasn't just 12 going to 6 abruptly.

For example, one side could go from 12 to 9 to 6 to 3 then 0. The other side could do the same so that the net was a constant 12 strands. Or you could make the taper in 12 steps again for a constant 12 strand diameter.

This came up because I want to splice 5/16 Amsteel to 5/16 Tenex, both 12 strand single braid. This is for a halyard. The line ended up over 1/2 inch thick in the splice, which might be too large for the new mast with internal halyards, not sure as I have not heard back from the guy building the mast. But in any event, while I wanted the line that will be in the area of the winch to be thicker than 5/16 to make it easier to handle, 1/2 inch seems too thick. I think removing some strands in the area of the splice will give me what I want but I just thought about the logical extension of this to all the way to constant diameter. The halyard has significant excess strength as it is built for stretch and as long as I have full diameter Amsteel on the winch, I should be OK stretch wise. I have not quite worked that out yet though.
