[QUOTE="Badge, post: 637716, member: 21082"] Thanks for the advice Pat. I'm using 3000 pre polish and then 100k polish atm. Is 100k too much? I do have some 14k I can use instead. And that stone has a pavillion of 42.5 degrees approx. because the SRB design for the 64 index had 42.1 degrees. The protractor on my machine is probably way off because trying to get 45 degrees for the table is closer to 46 than 45. I'll try to find the pic from Jeff Graham. The material I'm using is sub standard. Full of tiny flaws and black streaks and doesn't polish as well as the 2 sapphires I have cut so far but it is as you say good for practise. The one below is better than the SRB above but you still need to get the right angle to get any glimps of a sparkle. And I spent hours polishing it. Long way to go yet, but I'm enjoying the time spent learning. Cheers. Badge. [/QUOTE]
