Having recently started segmentation I've just noticed bowls I've turned developing ridges where the ring has shrunk a bit after finishing. My take on this is the wood glue is adding a lot of moisture to the wood, and as it dries the ring is shrinking. Is this the usual problem in segmentation? Knowing this, how long should a glued up ring be allowed to "cure" before stacking if it makes a difference. Should I leave the glued up bowl blank to dry like a roughed out blank and for how long?
