    What grit(s) from this vendor do you use? Aluminum oxide or silicon carbide? What size or sizes? I definitely would like to try making my ggs.

    I will review the videos and plan on getting the grit from gotgrit.com. I was just looking for your recommendation on what grit and what size to get from them.

    I used 600 grit silicon carbide. I got a pound of it from a local tool shop that also caters to jewelry and rock-hounds (lapidary, rock-polishing). A pound of SiC grit cost $8 a few years ago and is enough to last several lifetimes.

    I haven't read but a few of the replies here, but for almost twenty years now I've been making my own focus screens using Armour Etch. It chemically etches the glass to a matte finish. Like all chemical processes though, there are skills and tricks to be learned to make the best final product. Armour Etch can be found in many arts & craft supply stores. Always heed the warning labels. Don't get the chemical on anything you don't want etched . . . like the back side of the screen, or your eyeball.

    I should state that getting a perfectly even matte finish can be challenging. But if you need a working screen quickly this will work. Etching the screen multple times also helps with evenness.
