The sandblaster in action, frosting a test-strip of copper for one of Tetranitrate's secret projects.
Step 1: Materials
Sand got in my nose, between my teeth, ears, and despite the goggles, my eyes. When this was done, I looked sparkly from all the garnet sand dust on my face. Consider wearing a bandanna, especially if you have any respiratory issues. Actually, you really want to wear a respirator, to avoid silicosis. Use goggles if you have them. Swimming goggles (that seal over your eyes) or a snorkel might work best.
To construct the sandblaster, attach the hose to the air gun, and drop the other end into a bucket of garnet sand or other abrasive. Any even-sized abrasive should work - we grabbed this out of a pile of abrasive meant for the water jet.
Once everything is assembled, proceed to sandblast!
My jeans are indeed whiter.
