Good luck with the crystal refacing, Donald! A few suggestions if I may, based on hard-won experience:

First, choose your sandpaper types and grits carefully, as some papers will chip the glass. If you have an old junk crystal piece you can sacrifice, experiment on it first.

Second, be prepared to spend a lot more time and use more muscle to work the material (no surprise there).

Third, you MUST sand wet at all times, so use "wet-or-dry" sandpapers.

Fourth, for the final polish once you've got the facing about where you want it, try rubbing the table in an elliptical (almost circular) pattern over very fine sandpaper (e.g. 2000 grit), wet of course. I started doing this when I read that it's how they polish optical lenses.
