Edge-joining Plywood

I'm building a table where the legs are 3/4 inch oak plywood. The
"legs" are attached to the "feet" with a curved edge of 7 inch radius
- edge to edge. the curve is about 1/4 of a full circle. I can't get
buiscuits in because the buiscut cutter won't work on that kind of
inside curve. Dowels would be almost impossible to drill so they are
all parallel and aligned between the two parts.

I don't really want to get a slotting cutter for the router and use a
curved spline. Since the pieces are cut, I don't want to cut new
pieces and make a lap joint - I'm not sure about the looks of it
either.

I tried a test sample edge glued with yellow glue. I ripped it apart
by hand, but half the width of one piece had half the lamination tear
away.

Suggestions? Alternate joint reinforcement?, different glue or gluing
technique? (My test was to brush yellow glue on both edges and clamp
for 2 hours. Tested after they sat about 20 hours.)

BTW - the face grain is oriented at right angles between the two
pieces. I would think this make the layers always end grain to face
grain, every layer.

What about gluing a thin stip of solid oak as a buffer between the two
pieces of plywood? Might add some decoration - or not.

Thanks for the suggestions.
