I’ve been asked to make a round serving tray and I’m having problems finding a way to calculate/find a template to print for the “wall” of the tray. What I’m trying to find is a template that’ll let me cut the arched bits out to butt joint/stack them to make the wall of the tray. I’ve found things for woodturning but I’d end up needing 1.5” thick lumber to get a 3/4” thick wall. I’ve put a picture of what I’m trying to do. This is most likely something from a factory with steamed lumber.

This is what I’m going for – almost that size. I had thought about doing this since it seems to be the best way. My other thought was to make four 20” round panels. One is the base and the other 3 I’d use a router to cut my outer rim and then the leftover smaller circles would be cutting boards or lazy susans.

That’s how I would do it – create a panel and cut a ring out of it. Wood movement might be an issue, but it’s small and if dried and milled properly that shouldn’t be too bad.

look here:

from about 13’30” up to about 21’55” and then from 33’50” to 35’20”
no material waste while doing a curved panel.

It is in a Nordic language but more or less self explanatory.

How about a bent lamination? If you have a band saw its really not that hard to do.

I do rings on the router table as described in a frame project

That thin would be kinda scary though! 8^)
