So, I guess the thickness of the slab has as much to do with what one turns as anything.
Good point John. I've used my MacNaughton straight slicer to cut slabs because some log halves are just too deep. Many times I will core with a full half log and the turn off the top of the rim. From the largest bowl. The smaller ones don't seem to crack as much as ones above 14". I follow Reed Grey's technique and round the edges of the rim and wrap the rim with plastic wrap and duct tape. I have some ash at 23" drying in the garage that should be dry around August.
