This meetpoint design for a rose cut sphere yields a "true" sphere. All of the vertices are equidistant from its center. Begin by cutting a 48-sided cylindrical preform. The height of the preformed cylinder must be equal to or greater than its maximum width for you to have enough material when you get to the course 23 (pole) facets. When you cut the course 1 facets for the first hemisphere, create a level 'girdle' (equator) line at half the height of cylinder.
Transfer when you've finished the first hemisphere, and repeat the course 1-23 sequence on the second hemisphere.
If you cut a Snoball of your own, be sure and let me know what you've cut and how you made out.
