I see where you are coming from. In this case the original owner had the rig all screwed up. The chain plates involved served the purpose of backstays
for the staysail. Instead of leading them directly to the chain plates, he ran them through the spreaders. This put shear tension on the plates causing a hairline crack.
My friend is a mechanical engineer
with decades of experience and a list of patents to choke a horse. Much of his work involves stainless. Actually he bought my prior sailboat 15 years ago and still uses it. He examined the chain plates decided they didn't need to be replaced, although he could easily fabricate a new set, welded them, polished them and they look like factory new.
I trust a fellow sailor and a good friend. By the by he did fabricate a new bobstay fitting for the bow but he used thicker stainless than the original.
Thanks for the input. It's good that some of the new sailors
get the whole story. I do agree that welding is a solution in only a few cases.
