I always cut the table last. Lay in your break facets first and get the girdle thickness you want, then the mains, then the stars. I then polish in the reverse order (stars, mains, breaks). Then the table. My machine won’t go to 0°, so I have to take it out and use a table adapter.
I have cut a lot of transparent yellowish orthoclase, but I’ve never done any sunstone. Like to see a pic when you’re done.
