mike: apparently, you do not get it. asking a high heat bone charcoal mechanic to accept full financial responsibility, if his work goes wrong, is not the same thing as a general business liability disclaimer. you may not realize this, but most of the used guns i sell have not been worked on by any one i know. however, they may have been worked on by people that i do not know. to paraphrase don rumsfeld:
we know what we know
we know what we don't know
we also don't know what we don't know
i am getting kinda tired of all of this. lets let it go for a while?
