Yes, that is the best method and instructions I have found yet. He said it would take about 2 hours to do the job using 5 micron AL oxide.

Thank you, Glenn. I am taking mental notes on everyone's suggestions. I will not be rushing into this project. I probably will be hand grinding my GG. I like the simplicity of the process. I even have some powdered abrasives on hand.

Thank you, Bob.

Vapor blasting is new to me, but interesting.

That is a good point, Joe. I am willing to work with glass. So, does anyone have any experience with grinding their own glass they would like to share?

I need a 16X20 ground glass for a camera I am building. I prefer plastic for its durability, but I want quality equal to fine ground glass. I am willing to make my own. Has anyone any experience doing this that they would like to share?
