Splines would probably be easier, Don. You can do blind splines if you don't want the spline showing on the outer rim. That will keep the octagon flat and then you just have to line up the outside.
I just did a 10 segment ring in Walnut and didn't use anything for alignment. But my little project will have no stress on it so I didn't need dowels or splines or biscuits.
