Well, here is my fifth attempt at segmenting. I'm getting better, my joints are good and tight both between segments and rings. I worked hard and long fine turning my table saw sled to cut true angles (at least at 15 degrees) and I am careful to make sure that each and every ring is flat before glueing. What ya think?
Oh, it has a diameter of 11 1/2 inches and a hight of 4 inches.
