The newsgroup has..many times. What it boils down to, as far as I am
concerned, is what species of wood you intend to use.

White oak doesn't glue up well with epoxy. Epoxy works with mahogany and
pine, for example.

And glueing white oak with epoxy has also been covered a few times in this
newsgroup. It works good as long as you sand the oak across the grain. I
have never had a joint fail.

I have.

I did the sanding thing you are talking about when I made some laminated
ribs with White oak. They failed - right on the glue line. I suspect the
bending stresses of being under sail flexed the ribs and caused them to try
and slide along their length. But I don't know that for sure.


If you are going to glue white oak you might try resorcinal. It's water
resistant - not totally waterproof.

And it requires an absolutely tight fit and high clamping pressure.
Better stick to epoxy.

I've also used 3m 5200 successfully. Though you better not ever want to
remove the piece.
