Just wondering who else is dabbling in the glassware sandblast etching black arts?
I have been using an inexpensive 3 mil vinyl for a sandblast resist and it has worked out very well. Using a siphon feed only (no pressure pot), a 3HP 30 gallon compressor and a small sandblast cabinet with 180 to 220 grit aluminum oxide media. Also rigged up a water trap (bucket) system for exhausting the dust from the cabinet. No interior cabinet light(s)...simply a trouble lamp resting above on the cabinet cover.
Any other tips would be most welcome
