[QUOTE="Pat Hogen, post: 637688, member: 11720"] By the way, synthetic stone is very good to learn on, particularly syn sapphire/corundum, just don't use a 1200 prepolish lap at any time for corundum, go to 3k, 8k the polish. There is a good pic from Jeff Graham that says if your stone is not at this stage, almost mirror finish, no scratches, then it is pointless trying to get a good finish polish out of your stone. It was the best learning advice for me. [/QUOTE]
