[C320-list] Masthead sheaves - access

[Warren Updike]

I had a rigger do some work for me on the mast head and he replaced my main
halyard with his own climbing line. He used sail twine and a sailor's palm
to sew the butt ends of the two lines then taped them before pulling
through. Make sure both lines are near the same size.

Subject: [C320-list] Masthead sheaves - access

When we de-rigged our boat last winter we attached a thin 'mousing' line to
the spinnaker halyard so we could draw it back up the mast this spring when
we re-rigged.

It jammed!  I think what happened is that as the join of the halyard and
mousing line went over the sheave in the masthead it jumped it and the thin
mousing line wedged between the edge of the sheave and the side of the
block.

I've been up the mats to have a look, but  - unlike the boom end - the
masthead sheaves and blocks are enclosed with a 'cap' and both view and
access are minimal.

Does anyone have any bright ideas how to undo this jam in situ or do we have
to un-step the mast?

Thanks
