I borrowed this unit from a friend to etch some glass for an architectural project at home. I'd never done anything like that before but was pleased that it did an excellent (and fast) job. I used clear contact paper that I got at Ace hardware for the mask template. You can remove the cut-outs either before or after you adhere the contact paper to the glass, but for more complex designs like ours you really have to apply the contact paper first and then cut the "to be etched" parts out with an Exacto knife. It does generate a fine dust during use so you need to use it in a garage or outdoors with a simple doctors type face mask. The project turned out quite professional looking and our friends are amazed. A great little unit!

We use one of these machines to prepare fossils in our paleontology laboratory. The dual chambers are very convenient because we start our preparation with a more aggressive 120 grit aluminum oxide blast media to eat away the surrounding rock and then switch (at the push of a button) to the other chamber / wand containing softer dolomite (or 400 grit aluminum oxide) for more gentle close-in work on the bones themselves. Make sure you use a mask and goggles if you'll be working for sustained periods because it does kick up dust. Our compressor is very quiet but for absolute silence you can run one of these units for hours on just compressed air from a tank that you can fill up at the local gas station.
