Sounds good but you are assuming that the chain is not stretched - and
having seen how easy it was to bend the shank of a Wasi anchor and knowing
the displacement of an Amel i would be measuring the chain carefully before
i had it redipped Also we never use the cone clutch except when we are
using the drum when the cone clutch is fully off - we never stress the key
or keyway or have chain runaway as we drop the anchor using the down button
- surely that is what it is for???

The keyways on the bronze cones do get worn but an engineer can easily mill
out a new keyway to make them as good as new. The chain is prone to jumping
on the gypsy as it is only touching two links at a time and this wears the
gypsy making the problem worse. Replace the gypsy if this problem becomes
serious.The cones, gypsy and shaft keyways get damaged/worn by a jumping
chain if the cones are not kept greased because without it the cones can
suddenly grab the gypsy when the chain does a runaway and puts huge loads on
the whole thing. I know because I have done it and was lucky to find a great
engineer in Croatia who repaired the damage.
I had my 80mtr chain regalvanised in Spain for about 180 Euros. After one
season it is still as good as new, The process is called hot dipping. The
chain is tied to a hoist with wire so that it is in short lenths about 3 or
4 metres long and then dipped into boiling liquid with zinc electrodes in
the cauldron and comes out looking like new except that there is a bit of
zinc build up at the bottom end of each link from gravity during the
suspension treatment.Not important.
