I had some slices left over from the first bowl, not as many as needed for the original six slice pattern,
I decided to modify the pattern Pete Marken had charted up from 3/4” wide rings to 1/2”, redoing the calculations on the chart resulting in only needing four slices. I also added a few more solid discs at the bottom to give it more height and used a plug of sycamore as the base.
John Lucas I used the sanding sealer as you recommended, looks better but maybe the light color wood has more color to it than it should have.
