I aggree that you may have problems with epoxy and oak especially if there is any wetting of the wood but oak is a good wood and could make a beautiful and strong boat.

How about resorsinol ( cant spell ) you know that dark red to black glue with a powder catalist. really strong...bonds to oak too. good for laminating but not so good for fillets or saturating 'glass for clear layups.

other products are available probably expensive and hard to find (urethanes), perhaps even polyester resin would work, My first canoe was built using it, 14yars old and going strong.

try it...it might work.
: Tom - Oak is a nice hard tough wood, but according to Sally Van Leuven in her
: book "Illustrated Guide to Wood Strip Canoe Building", there is
: something in oak that disrupts the structure of epoxy. She relates how she
: epoxied oak gunwales to a canoe without screws, and about a year later the
: epoxy glue joints came apart. Oak contains a goodly amount of tannic acid,
: which would tend to neutralize the alkaline epoxy. If you did decide to
: try it, consider 3/16" strips rather than the normal 1/4" to
: conserve weight. You might also try neutralizing the tannic acid before
: applying fiberglass, but that would tend to change the color of the oak.
