   Stan,

   My recommendation would to be to use splined mitre joints. Finger joints such as dove tails or box joints are for joining end grain to end grain and ply wood does not lend itself well to these kinds of joints.

   *A box joint would be all right but a dovetail joint will usally just result in a lot of rear out.Scott

   *you could also use a rabbet dado joint, which should be strong enough. if you veneer it after it has been assembled, something as simple as a butt joint will look like a perfect mitre from the sides.

   *I'm not so sure about veneering over a butt joint or rabbeted dado joint. It's possible that the joint will eventually telegraph through the veneer and give it a place to separate very close to the corner - not a good thing. If you're going to veneer the safest bet is the splined miter as suggested earlier.Best,Seth

   *Thanks for the input. A splined miter makes sense.

   *Stan, I've used a lock miter with very good results in birch plywood.

   *I agree with Sherman that a lock mitre (made with a lock mitre router bit, router in router table) gives excellent results. It's easy to clamp. Usually you only have to clamp from one direction (instead of two). Most router bit makers have these bits.
