I have an 80 pound pressure blaster that you're welcome to use.
It makes a mess, but it works great as long as you have a compressor large enough to push it. I ran it on a 20 gallon compressor before, it just takes time to stop and go stop and go letting the compressor catch up.
I used it to sandblast my frame about seven years ago.
It works great and I'm not using it. so you can take your time with it. What I like to do for small projects is build a little work area out of plastic tarps. That way you can just sweep up the media, pour it through a screen and reuse it.
