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

Hi Brian. The most straightforward way to do this would be to glue up segmented staves. I have a computer program that can generate the compound cutting angle if you let me know how many staves you would need, or I can suggest an appropriated number of staves if you let me know the thickness of the materials you will be using and the diameter of the tray. I think 45deg. is a pretty extreme angle and will make it all the more difficult to not only glue up, but also to glue to the tray. Without a lathe there would also be quite a bit of hand work involved to get it rounded after glue-up. maybe there is another way to do this, but I don’t know about it.
