I am now faced with the situation of my county not allowing me to sell radiators from AC units. I get a few of them and they are piling up. I can drive them to the next county or take the time to pull the copper from them. I am going to try and take the copper from them. There is a viseo somewhere here about taking a utility knife and making a cut to pop the copper out. I will probably try that soon as I have about a hundred pounds of it laying around.
