Introduction: Sand Blaster
This is very easy to make and works very well. I got this idea from the YouTube channel The King Of Random.
Step 1: What You Need
Supplies: plastic bottle, pen, and an air gun.
Tools: drill, bits, and a knife.
Step 2: Very Important
You also need an air compressor.
Step 3: Cutting the Tube
Take out the tube of ink and clean it out. Cut a trench out like in the picture.
Important: the tube needs to be about 3/16 of an inch.
Step 4: Drill a Hole
Drill a hole in the bottle that the tube can fit in snuggly.
Step 5: Putting It Together
Put the tube in the bottle with the cut out part facing the mouth of the bottle.
Step 6: Finished
Fill the bottle half way with sand. Put the air gun and point at what you want to blast and blow.
My air compressor is at 120psi but I don't do full throttle. Just watch the top of the bottle and make sure it doesn't pop up too much.
