My lathe won't take anything more than 12 inches in diameter. What would be the minimum thickness to turn a platter with tenon and base?
 
If you are referring to minimum thickness of the blank, I’ve used 3/4” thickness many times. Using a scrap glue block for the tenon gives you a little more leeway on the shape.
 
I’ve made plate size (~11”) with 3/4” stock but I think they are a little thinner than I like (even if you use a glue block). 4/4 allows a better proportioned plate in my opinion.
 
I turn a lot of platters from 3/4" stock up to about 11". I cut an 1/8" or so mortiss. You have to be very careful when turning the bowl portion. I use my custom depth gauge to check so that I dont make a funnel.
I turn a lot if small platters I call change dishes. They are 6" or so and turned from 3/4" stock. Here is a link to my funnel prevention video. Thr concept came from the geniuses at woodturnerswonders

John Lucas, that is a simple and if used correctly, very accurate funnel prevention tool.

I do a lot of very small bowls, this tool will/should, prevent me making more of them into a colander!

Need to watch the video.
 
Thanks. Another turning on the to-do list.
Hey, Gramps, try to get some quarter sawn wood to use. You're in pretty good hardwood country, so maybe even find some end cuts from a mill. The flatsawn wood you get from the lumber yard will possibly warp, even though the wood is 'dry.' (Out here in arid country, it definitely warps) Quarter sawn should stay flat indefinitely.

Dean going by robo hippy's post, I might have some pecan that would fit his noted dimensions. Dry as a two hour sermon.
