This is just in from the mail bag:
I can't thank you enough for recommending the 600 cutting lap and BA5T to pre-polish with 3,000 diamond powder and then to use the BA5T for the final polish with 50,000 mesh diamond powder for cutting corundum. I purchased the 2 BA5T's and the 600 cutting lap. I just finished cutting my first Montana sapphire using this system. What a joy to use the BA5T's. I polished the sapphire like it was butter. It cut my pre-polish and polishing time by at least a factor 4. It polish those nasty tiny pits right out of the stone in nothing flat. The only thing I have to watch out for is overheating when polishing and cutting back on the pressure applied especially with the small sapphires. Again, a big thank you! Your recommendation is a huge time saver and it makes cutting and polishing sapphires a joy rather than dreading the polishing time.
This guy is following my recommended sequencing for cutting and polishing Corundum. It’s great to see someone getting the FUN results that faceting should be providing. How many more stones will a person cut when they’re having FUN doing it? This kind of feedback is the reason I built this site. Thanks very much!
