As I have mentioned before, big bowls do not sell near as good as smaller ones in my area but I do like to keep one or two big ones on hand at all times .
The laminated board for this one was 12" x 12"
Here it is with the rings right off the RM and glued up and in the press .
Then I got to wondering if my Rikon lathe that is advertised as a twelve inch one is indeed a full 12 " so I mounted it on the lathe and low and behold I was able to slip a piece of 1/16 " thick slat of wood between the bowl and the bed of the lathe .
I think with this big boy I will let the glue cure at least overnight before I start sanding it . I have been known to start sanding after only a few hours of glue up but not this time .
