Hi Kris. I use a 15 degree cut on my pieces. I usually start with 1" pieces and increment by 1/4" for each additional ring. After the rings are all glued together, they are stacked one on top of the other, glued and turned slightly so that the joints are staggered. Then it’s time to put it on the lathe and start turning . You tube has many great videos also to help. Good luck and Happy Turning.
