HF 110lb Blaster questions

I've used one of them before, similar to the setup I have in the shop.

For striping frames, floors, wheels, and other stuff that you don't have to worry about warping, I use regular sand (you can pick it up in bags at Lowes), I have a large funnel with a Flour Sifter shoved in it. I just dump the sand through that and it separates the chunks that won't go through the nozzle.

BLAST OUTSIDE!!!! Trust me. I tried blasting some small stuff in the shop once, what a mess. When you blast, try to have a large fan set up behind you to blow the cloud away from you. Wear a Respirator, Goggles (preferably Snorkeling style goggles, trust me) and a Painting Suit (with a hood)

Shake the blaster tank every once in a while, even though it's pressurized, sometimes you get a bit of a "funnel" sucked through the center of the sand, and then it sprays mostly air with bits of sand.
