I like the Stupidity disclaimer in this Instructable.

Step 2: Don't Be Stupid
Seems pretty obvious to most of us, but I'm going to say it anyways. This project has the potential to seriously injure or kill you if you act like an idiot or don't know what you're doing. If you have never worked with metal before, this is probably not a good introductory project. If you have never used a lathe, don't try to make your own dies without help and supervision. If you are the kind of person who cuts corners and blatantly disregards their own safety, go somewhere else. Also, if you disregard my warnings and stupidly attempt to do this project even though you don't know what you're doing, I am not responsible for you cutting off fingers or killing yourself as a result. Now that we've gotten that out of the way, lets get building!
