I hear you Bob. I have a large blast cabinet also. The bad thing is when friends find out, they want you to do all kinds of things. I don't mind small stuff, but one guy wanted me to blast an old fire hydrant. Or they ask for one thing, like a manifold I did for a friend, then all of the sudden he wanted 7 more things done. I use to blast Harley tanks and fenders, auto parts etc. It cost too much to be running the compressor, using the media, wearing out tips etc to be doing it all the time for free. Plus my vac system is loud. I don't like that the most.
