Re: Embedded Chain plate maint/replacement
Let's see if I can describe this well - I don't have a good drawing tool that is easy to use.
1) make some knees out of g-10 - laminate to a 1 inch thickness. Put them in - one per plate with epoxy, fillets and heavy glass (maybe CF, double layer). Smooth, fair, paint.
2) turn the plates 90 degrees, bolt through the knees, backed on the other side.
3) build joinery back where and how I like.
I'd have inspectable plates, be able to see any leaks and rectify and I 'think' just as strong. The knees would run from the deck to the core area, really don't need to be much more than the width of the plate as it's more about spreading the load - and that's on the fillets and fiber glass tabs and tapes.
BTW - let's call the discussion on 'it's on the bolts' pretty much done. The bolts can pretty much hold the entire weight separately - look up the tensile and sheer strengths.
The shrouds are rated about 9k SWL - bolts pretty much better than that.
Lessons learned are opportunities earned.
