I am going to take a stab at a segmented bowl. When gluing together the
"rings" of segments, how does one ensure that the rings remain centered
around the axis rotation for the glue block? It would seem to be that if
done by eye it would be OK for a layer or three but any error could
accumulate. If there a trick or technique for keeping the stacked rings
concentric?

Well, only doing a layer at a time helps.

Using the same inside or outside diameter for rings (and wasting wood as
a result) helps. If you were setting up "production" you might waste
less wood with a clamp jig. For a one-off that needs to be precisely
aligned, you could set a few "long" segments in the rings, so that
either the inside (use a pin at center) or the outside could be
registered without wasting a lot of wood.

Depending on the particular effect you are after with your segment
patterns, slight errors may not be noticeable - or they might be.
