Rod,
 
I have done a lot of ES and here are some tips that I have found that work great.
 
1.  Try to avoid using metal bond diamonds, the have a tendency to burn the resin.
 
2.  You must use diamonds specifically for ES..I like the Alpha Ceramica EX
 
3.  Use slow RPM ,  Higher RPM can also burn the resins
 
4. You should be able to get factory shine using the 3000 grit..just work it a long time.
 
 
I plan on showing this technique in an upcoming advanced seminar..in the meantime I did shoot a video on this very topic that is available through NTC   www.ntc-stone.com

Hey Guys,
 
Went to look at my first E.S. job I don't know the name of the stone definately man made.
 
Got the call to grind the floor as the installer left alot of lips,so i took an extra piece to use with my cup wheel and metals to make sure I can get the scratches out and only had moderate success.I took it up to 400 grit marble diamonds and finished with mb's 400 grit honing powder the finish is almost flawless if not for all the little tiny scratches I can still see from the metals,mind you, you have to lOok very close and from standing you would not even see them but I can and I know they are there.
 
I tried a concrete 120 grit diamond to see if it helped remove my scratches from the metals and really didn't work any better than the resin marble diamonds,then tried some granite diamonds and they seemed to work a little better but still did not remove the tiny scratches.Keep in mind this is with a makita 9227
 
Looking for some advice from some of you that have grinded e.s. before.This stuff is very hard to scratch we ran a knife across the top and did nothing,seems very similar to grantie and wondering if I need to treat it the same way.
 
Thanks in advance

Latest interesting customer is a Baltic brown counter with a large 2" by 3" quartz right in the middle. I have tried to load the pic several times but it keeps coming back. Anyway, he wants to know if the bright white quartz can be colored in anyway. I say no but if anyone has some input it would be appreciated.
 
Thanks:
