[C320-list] SEIZED SHEAVES ON END OF BOOM

[Mike Paris]

I removed mine last Spring but it was quite a struggle. I sprayed lubricant 
(Sail lube I think) and tied a very short line around one of the edge 
sheaves to make a small circle around it. I then inserted a small bar (a 
rachet handle), twisted it to tighten the loop, and used it as lever. I did 
the same to the sheave on the other side and worked alternately for a while 
on each side. It took probably about an hour but they came loose. Once I got 
even a tiny bit of movement it went much easier.

Note: they have already frozen again!
