Ernie,
I saw an article once(which I can’t locate) on how to accurately cut and join two or more curved pieces for a table top (or a door) out of solid wood. For example how would I cut a yin and yang curve accurately for a table top so that one side of the top could be a dark wood and one side a light wood.
Many thanks,
Adam Fisher

Dear Adam,
The way I would do it would be to lay out the curve you desired on a scrap piece of plywood or MDF. I would then band saw to the layout and fair the edge with whatever tools I had. This could be an oscillating spindle sander, a compass plane, a spoke shave or just sand paper and elbow grease. I would then trace this template onto each board and rough cut to the line. I would then clamp the template to each edge in turn and using a super flush trim bit, bring each piece to exactly match the template. I would then glue as normal. There are probably other good solutions but that is mine.
With best regards,
Ernie Conover
Thanks so much for you quick reply. Your solution sounds very good--probably better than what I was thinking. I was wondering if it is possible to lay the two boards where the curve will be on top of one another and band saw along the line, then remove the waste pieces and put the good pieces together. And yet, I was wondering if the thickness of the kerf and any roughness in the bandsawing prevent a good fit. Is there any chance this would work?I hope to see you again when you come to Long Island.Warm best wishes,
Adam
Dear Adam,The crux of the problem of your scheme is the roughness of cut of your band saw blade. It would a very distinct (AKA Ugly) glue line. The router also insures that the smooth arcs of the joint are perfect right angles to the surfaces. I always enjoy visiting Long Island!With best regards,
Ernie
Once again, thanks very, very much. You help clears the way for me to work on what I hope will be a very interesting round kitchen table.BTW, it was so nice to be in touch with you again.
Warm best wishes,
Adam
There is a video on this website that shows a person making a router template to do something similar. It might be helpful to you.
