Rose Tear 224a-96 Cutting Notes

This meetpoint design for a rose cut tear incorporates identical plan views for both hemispheres. Begin by cutting a 16-sided cylindrical preform. The height of the preformed cylinder must be at least 1.43 times greater than its maximum width for you to have enough material when you get to the course 7 and g (pole) facets. When you cut the course 1 facets for the A hemisphere, create a level 'girdle' (equator) line dividing the height of cylinder proportionately, allowing 1.85 times more for the z dimension of the B hemisphere as the A hemisphere.

Transfer when you've finished the first hemisphere, and cut the course a-g sequence on the second hemisphere.

If you cut a Rose Tear 224a-96 of your own, be sure and let me know what you've cut and how you made out.
