re: How can I make splayed side for a round tray?

I was thinking today that maybe putting together a segmented circle, rough cutting it with a jigsaw, then using some plywood circles as a template for shaping with the router. The sides don’t have to be 45° precisely, I just want them splayed. So maybe shaping the inside (the top side of the splay) with an ogee or something and the outside (underside of the splay) with a 45 bit or some thing that will round up the edge would work.

I do have a bandsaw, but I also have a router table circle jig big enough so probably the router idea would be better. I’ll give out a go on some tubafores before buying nice lumber.
