Willie:
 
I have a 64 index. I had to go with increments of 11 four times and 10 twice to have it work out. I found a pattern for an egg which I modified; I was only interested in the rounded bottom part, and I reduced the angles by nearly half. I wanted the top of the head to be domed. Thanks to you guys posting the links for faceting diagrams, I was able to find one I could work with.

I had trouble with the facets tying into the forehead, since I had to do them on the edge of the lap. Since I couldn't back off any further, they were partial curved facets. I had to go back with stones to try to smooth them out and it was kind of a mess. The platen is slightly out of whack so I had to hold the stone loosely and let it go up and down and I was scared I would crack the face. And, on my last polishing at 8000, my copper lap (which unknown to me had a coat of lacquer on it) scratched the top facet. I had nothing left I could work with at that point, and was afraid of messing up the copper lap. It was brand new and didn't have any opportunity of getting contaminated, at least by me. I had handmade corian laps for the other grits, except for 100 and 200.

I admire faceters patience and attention to detail greatly. I don't know that it's the work for me ( I work sloppy), but I like the results. I know I'll do more, I'll probably try something more classical next time. And I really ought to get a better index; there are very few diagrams for a 64.
