Are you planning to do any rough turning as you go?
I really like the look of your bowl after your initial turning.
Alignment, I can only suspect what may have happened. I am sure there are others on the forum that have more experience and can comment.
Being 48 segments certainly makes this a difficult piece. My comments are only me thinking out loud and are certainly not to be taken as criticism. Taking a thicker piece and slicing it I would try to keep each ring in order and would not flip them. If the ring is slightly out of round I think it will cause you issues.
When making the taller ring I would want to ensure that the pieces were at 90 degrees to the base and have no lean when you glued it. Right back to the start I would make sure your segeasy sled was aligned with the back edge of the sled to the wedge to ensure that the segments are equal on both sides and not spiralling off centre ( which I'm sure they are not). Could your ring have slipped while gluing? Probably not as you used your Cole Jaws to hold it.
With any project like this I always dry fit each ring, rotate it to check every 90 degrees then mark it where I want it to be before applying the glue.
You had said you rotated 90 degrees to take the second picture. How does it match at 180 degrees? And 270 degrees?
I wish I could make the larger rings and slice it like that, would certainly speed things up when I get started again.
In your picture of the glue up it looks like the outer edges are not aligned with each other. This may be part of your problem especially since you split the glue up and flipped the resulting pieces.
