CD25 chainplate repair: source or DIY?

[Kilgore]

Rust stains are tracking down from my port backing plates, which upon inspection are flaking badly. I can only assume the chainplate underneath is toast.

The starboard side backing plate is 'rusty' but looks otherwise intact. I haven't popped the access panels to look at the bow/stern stays yet.

Is the repair a day/weekend/weeklong project? What would I expect to pay (ballpark) to have it done in my neck of the woods?

Ours are in identical, if not worse, condition. Other than what's already been written about on this board, we don't have any new ideas so we'll be interested in the responses, too.

This is what dropped out:

And this is my repair

To accomplish that, one needs to expand the round opening
access.

Place a towel or rags under to catch dropped tools.
Make plywood templates to fit before cutting stainless.

bmail if questions arise.
Hope this helps.

Dick,

How hard/time consuming was your repair, on a scale of 1-10?

Kilgore,
I sent you a PM.

Progress, I think. Access was cut, the shrouds and stanchion removed , and flaked corroded mild steel backing plates chiseled off what appears to be the chain plate.

It's intact and stout, not budging even with a pry bar. I was under the impression only the CD27s and up had plates glassed into the hull. Everything above the plate is dry and hard.

Is that rust behind the innermost layer of glass on the hull?

Any suggestions at this point?

[tartansailor]

Count on rust on the top surface because that is where water enters;
unfortunately.

My plan up to this point was to fab up a new SS backing plate, coat the existing surfaces in epoxy and bolt everything back up.
Should I be doing more?

Does anyone know if CD25s chainplates were constructed as described for a CD28 here:
