Deck,, core repair,, now the fiberglass,, getting it level..

[Jasper Windvane]

Let's see; I cut open the deck, dug out the bad core,, cleaned,
sanded,, got new core.. put the new core in.. used balsa..
This is on the port side, cabin roof, bristol 32.

Today,, I was planning the fiberglass and I realized the top
edge of my cutout ,, the original thickness of deck is small
than the bottom edge.. At the bottom edge,, kinda thick.. deck.

I got to thinking >> put in a piece of fiberglass,,, along the bottom
edge,, bring it up a few inches.
Then,, put on my large cutout piece,, and follow with my smaller cutout
piece.. this way the glass will be about level with the old deck, cabin roof

What you think..

The first piece will be kinda a spacer .. or think of it as a thicker piece
of balsa..

Then the two layers of 1708 biax..

Any thoughts?

Do you by chance have a photo, or a drawing? I can't quite picture what you've got there.

You might be overthinking.

when you lay your cutout deck skin into place (dry-fit), how far below the existing deck surface is it? If it's less than 1/8" low, I wouldn't worry about it.
The thickened epoxy you'll use to re-install the old skin will easily bridge that. Go the usual route of perforating the skin with 1/4" holes every 4" or so, screed the epoxy and lay the skin juuuuuuuust a smidge below the existing. Tape, fair, and paint.
