Came on this thread late, so if this has already been said, sorry!

I changed my halyards to all rope years ago, and used the same rope/wire sheaves. ‎No noticeable wear on the new line...and none on my hands either, for the 4 or 5 years I had all rope on the old sheaves.

When I took my mast down next, I rebuilt the mastead sheave box and installed all new, rope only sheaves from Zephyrworks out of Port Townsend, Washington. My boat is a bit smaller, but at $38 a sheave, I thought it was a no-brainer!

Never had any problems to this day!

Or by some Double Braid with a Spectra or Dyneema core and strip and taper the cover to approximate the length of wire?

Just a thought, but why not splice some dyneema to a rope for your halyard? You could use same sheaves and have a halyard that is lighter, cheaper, corrosion free, etc. I am hoping to replace the last wire halyard on our boat like this when I get a chance

Usually, all that is needed to refurbish these sheaves is to press out and replace the oilite bronze bushing, widely available at auto parts stores or bearing suppliers. I did all my masthead sheaves a few years ago, got the bushings at Princess Auto.
