[Public-List] Check that standing rigging-- especially this kind of terminal

Typically when you swage wire you should turn the wire around a thimble or deadeye of some kind.  I don't know what the recommended bending radius should be , I suspect it's 5 to 1 or better.   that takes the bending stress off the wire, hence the wire strands don't break before their time.  If 5:1, 1/4'' wire would be turned around a 1 1/4" thimble.  

BTW,  I heard the wire manufacturers recommend replacing wire Every seven years, although a San Francisco rigging shop that does a lot of Pacific Cup and Transpac Race boats said they have seem some serviceable wire that was 12 years old- which they replaced.  A guy on a Cal 25 next to me in the Marina has 25 year old wire - nothing's broke yet he says,  waiting for next year to replace!  Iam thinking Wow, how's that for living on the edge.
