One thing no one has hit on is your homeowner's insurance. You might want to make sure in your policy that having torches will not negate coverage if God forbid you have a fire. I only bring it up because I know someone who was in that very unfortunate situation. His entire shop, several customer cars, engines and several of his cars burned to the ground a few years ago. He HAD insurance, but neglected to tell them about his torch setup. Yup. They refused to cover it. Just something to think about.
