I smelt outside, and cast in an ex-store-room that I've converted into a reloading/casting room. I's about 6x12, and lined with cabinets, and a bench I made next to one wall. If the fluxing smoke gets too oppressive, I can open the door, and the door to the back yard, and vent the smoke so I can see again. Weather here is so benign that a space heater is all I need in the dead of winter to keep everything snug. Problem is I have to make sure it's on the other circuit from the pot, or the breaker blows, and it's a trek to the panel to reset the breaker. I will NOT include a picture - I am totally embarrassed by how messy it is.
