Sandblasting

[BADAZ chevy guy]

After getting prices to have my frame sandblasted, I've decided to build my own media blaster. Always wanted one anyway. What type of Eco friendly media should I use? I'll be blasting the frame, suspension parts, drive shaft, etc. And maybe some of the body panels. I've had a few things blasted in the past, but I never asked what the guy what he was using for media.
If I can do this, I'm thinking of making a mobile sandblasting unit I can mount on a trailer. I already have a 450 gal, 2 stage duel head compressor with that I can mount a gas, or diesel, motor on. And a 30 gal compressor tank I can convert to a presser pot.
Maybe I'm dreaming to big, but for 10 years now I've been trying to figure a way to make enough money to get off of SSDI and still not kill myself in the process.

Check out Eastwood's media.  They give a brief description of use.  Hope this helps.

      One of my best friends own's a media blasting company.  He did my frame for me, a lot of automotive guys are using crushed walnut shells these days.  It is the friendliest to automotive parts, especially small gauge metal.  It is not suppose to leave "pot" marks like sand and glass will.
      I guess it would depend on what you want to blast and what materials you can get cheap enough.

if you can find them, i bet there are people who would gladly let you rake up and take walnuts out of their yard
