Another vase but of my design using segment pro to get the specs..Peruvian walnut,yellowheart,maple,osage orange,and padauk. 72 segments per ring,about 41 layers. Butchered the first 3-4 rings trying to round off and blend into upper layers with bowl gouge, Decided to redo the first 4 layers and then use a Merlin 2 mini grinder to contour and blend into the layers without sacrificing inherent strength in lower section of vase. Holding by hand course to medium grade sandpaper with the lathe on, final contouring gave a satisfying blend ..I then reattached the upper ring assembly carefully and was delighted there was no noticeable wobble in the final steps ..
