Folks, what am I doing wrong?
I must confess I am somewhat disappointed with my first attempt at polishing. What I did was apply each side of the ingot to the following grits on a power sander for 30 seconds each: 60, 80, 100, 120, 150, 220, 400, 500, 600, 800, 1000, and 2000.
For the most part I obtain mirror finishes, EXCEPT for some scratching and pitting. I found 3 serious pits that not even sanding at 60 grit could get rid of. Also, it seemed that some of the sandpapers introduced scratches that could not be removed at later stages.
I’ve posted high resolution pictures in the hopes that the master polishers could provide me with some advice.
Thanks in advance!
