I don't have a blasting cabinet as you would know. When I have an item or two to blast, I get a clear 55 gal clear garbage bag. Put the item in, stick in the blasting gun, wrap a bungee cord over the bag around my arm and blast away. This way you can see what you are doing and it keeps the mess to a minimum. I had purchased a sand blaster many years ago from Sears and it has paid for itself many times over. Just be sure to use a water trap and drain the air tank of any accumulated water before blasting.
