Has anyone ever converted a flammable liquid storage cabinet into a smoker? I have access to several of them of different sizes but they have been in research labs for years and being discarded. I'm a little leary of what might have been stored in them over the years or will a good burn out kill everything. Just looking at them they'd be perfect to convert to gas or electric. Good solid 1 in walls. Not sure if hollow or insulated. Got some corrosive cabinets as well.
