Re: 35 year old standing rigging - but rigger says it's ok
some more interesting information:
Wire Cable: Un-stepping the rig is also the time to consider renewals and/or
replacements associated with rigging wire cycles. A rigging wire cycle is a
recommended replacement/renewal duty life cycle interval. Industry sources
consulted provided the following general guidelines for replacement/renewal
subject to regular detailed visual examinations, environmental conditions and
regular maintenance.
Change end fittings every 2nd cycle or 12 years;
…
Change wires every cycle or 6 years;
Change chain plates every 3rd cycle or 18 years.

…While rod will generally last longer than wire, re-heading is usually recommended after disassembly or as specified by the manufacturer.
