I was working on rebuilding an old carb for a guy today and while sandblasting the parts, I happen to think that the method we devised a few years ago might interest you guys. When blasting small parts like in a carb, they are impossible to hold on to. So, I went and got two hand held sifting screens, and I stack them together. I think the pics will explain it best.

I used two different screens, so that they were different sizes. That way, the parts can move around. I just shake the screen while sandblasting the parts so it gets all sides. If you are doing, say, a small spring and it blows around too much, just reverse which screen is on top, and it will "hold" the part in place. Works pretty good I say!!
