Jason,

On Magic, the Jib halyard currently exits the mast below the forestay pin. Above the forestay pin are two sheaves that are occupied by the #1 spin halyard and the #2 spin halyard. Should we remove the old #2 spin halyard and use that for our jib halyard and not worry about the "original sheave"?

:: Mike,
::
:: Sounds like you still have the original sheaves in the
:: mast. You want to give Ballanger spars a call and have a
:: couple new ones sent to you. The original ones are for
:: wire halyards and will start eating up your nice
:: high-tech halyards.
::
:: To answer your question though, you are probably going
:: to want to drop the mast to replace them. Both halyards
:: and the forestay ride on the same pin. So, to replace
:: the sheave you need to remove the shaft (pin) that goes
:: through both sheaves and the forestay eye. It can be
:: tricky to thread the needle through all three items with
:: the mast down, with the mast up would be very
:: interesting. I suppose it could be done if you held the
:: mast in place with the topping lift, but I would not
:: recommend it.
::
:: One hint, when installing the new shives make sure you
:: use a small piece of line looped around the groove of
:: the sheave, as if it were a halyard running around the
:: sheave. If you don't you will likely drop the sheave
:: inside the mast and spend several hours trying to fish
:: it out of the mast. Ask me how I know this!
::
:: Cheers,

:: Jason
