Raised chainplate deck fittings question

I'm sure to get a wide variety of responses, from why would you do that? etc.

I have my mast down, have new standing rigging waiting to be raised. Decided to raise the chainplates. Have polished the stainless hardware, and re-epoxyed the chainplate hole site.

Question: In using the modeling clay (as a form) such as in "this old boat" should I sand the gelcoat down to the fiberglass layer? I am using epoxy resin. Or will the epoxy stick to the gelcoat.

Thanks!

Yes I would sand to glass so you get the best bond

Yep -- I'm in full agreement with Tom.

Here's the reasoning. Gelcoat is simply polyester resin thickened with talc; it has little inherent structural properties. If you have that layer between the original glass and your epoxy risers, then you have two bonds that could fail (gel to glass; epoxy to gel) instead of just one.

For a "do it right the first time" solution, sand down until you hit the glass and build your risers from there.

Re: Raised chainplate deck fittings question

Thanks! One other question. So the new chainplate mount is basically epoxy resin, with some filler. The old screws for the chainplate cover looked like wood screws and didn't go very deep. Can I still use the wood screws on the raised epoxy mount? I would guess you predrill a hole slightly smaller than the screw. Other choice in screws? Tap it? Sorry, I did try to research this, couldn't find much.

Thanks again,

Chris

I'd use self tapping screws. Another option is to tap threads into the epoxy and use machine screws - there is no real stress on those fasteners so the epoxy threads will hold no problem.

Self tappers will work as well and are less trouble to install though.

Forget wood screws - they are for wood.
