I did some DIY sandblasting about two years ago using this.

I was cleaning up some old wire wheels for a british sports car. I used play sand and laid out a large tarp in the back yard. You must use a respirator and other protection.
It's a big mess.
My advise is that you skip the sand blasting and use paint stripper instead.
It's not worth the investment and you are better off taking it to someone to sandblast it for you.
Sand blasting is best for smaller items that you can fit into a sandblasting cabinet.
