I just got a philco fridge and looking to turn it in to a smoker Ive seen a lot of Pict's mostly of a electric or propane smoker not to many with a fire box off of it. I'm loo kin to make a fire box and about 1/3 the size of the fridge. I'M also going to make a section on top of the fire box for hot grilling/ warming oven Then set it about a foot away from the fridge and use tubing, what kind and how big should i use for it. I'm thinking of putting a propane line into it as well just to regulate heat and also turn up the heat on cold winter days. if anyone has Pict's esp. of a Philco fridge that would be awsome and give me some ideas as well. Also wondering on how to seal the door with fire rope anyone have a idea on that Ive herd that the stuff they give you falls off in a few weeks so silicone it? or screw it in? what can i do there thanks
