Tom - I posted this early in 2016 Etched Glass - Not Laser Made
While I’ve still not used my GF to cut stencil for sand (really soda) blasting glass as I find it easier to cut vinyl on a vinyl cutter. The concept is the same once you get to the sand blasting. I started with a very basic kit from Harbor Freight, the glass in the post above was made with that tool. I still use that basic setup, but I built a very basic containment box with a rubber maid box a couple toilet flanges and a pair of rubber gloves, all from Home Depot. This was simply to reduce the mess I was making in the yard.
I’ve added to my sand blaster collection a larger free standing heavy duty sand blaster from Harbor Freight, still no enclosure for this unit so it makes a big mess when I use it. With Black Beauty grit in this unit I can quickly remove paint and rust for metal. I’d still like to try etching wood with it, just have not had the time to find or make a good design and try it.
Enjoy the journey into sand / soda blasting. As @jbv said
