Protecting Glass in Sandblasting Cabinets
Protecting the glass in sandblasting cabinets
We did a lot of cabinet sandblasting years ago before we switched to a chemical approach.
What worked best for us was to make a sandwich consisting of a perforated steel sheet, a very thin piece of plastic and then the glass. As I recall the cabinet came from Grainger with a perforated steel sheet and the glass already in.
As near as I can recall the steel sheet had rows of holes that were maybe 0.1” in diameter. Most of the sheet was steel but you could see through the rows of holes well enough to work.
I think the frame had screws to take it apart so that you could replace the glass. We got some plastic and cut it to size with the office paper cutter. It generally lasted a couple days. It only took a couple minutes to undo the two wing nuts, remove the glass, replace the plastic in and put the whole thing back together.
