Fruits Of My Labor (A-113)

Keep on it.
If you are making built-in water tanks where you will use epoxy and glass to line the tank...
I would consider using plain fiberglass sheet for the baffles - no wood, even if covered.

You can make up flat sheet by laying out cloth on MYLAR film.
Douse it with epoxy, squeegy it with as many layers of cloth you want
then place another piece of mylar film on top.
Then a piece of flat plywood with some weight on top of it.
Wait til you see what you get!!! Wonderful!

Small tanks with a surge baffle supported on all sides can be fairly thin imco, like maybe 1/8".
That's what I put in mine. Have fun gluing in the top with the baffle(s) in place!
If you plan on coating the inside with a potable-water epoxy, that thin baffle will fatten up and be amazingly stiff.
