Welcome to the forum, John. I'm Julie from Texas. On your bowl, glue up the side rings without putting on the bottom yet. Get the inside of the bowl to your liking. If you have a spindle sander or a drum sander on a flex shaft is the easiest way, if not, a simple drum on your drill press will do. They also make an inflatable sanding drum that is fantastic. Anyway, get the inside to your likeing and then attach the bottom. Then sand the outside to where you want it. It's a little time consuming but well worth the effort for a beautiful bowl.
