Looking for guidance on how to best glue on the rings for a segmented bowl. I'm flattening the glued up rings on a drum sander, and trying to flatten the glued up stack on the lathe, but am still not getting consistently good results. I'm using the tailstock with a 2 x 3/4 ply circle cull to press each ring on as I glue. I still see small areas where the joint isn't as tight as it should be. Any thoughts on a process that would give me consistently good results?

Thanks, Mike
