Okay so I am new to this site and already addicted! I got a free commercial fridge and thought piece of cake to make it a smoker right, NOT. I started today and am totally frustrated. I cannot figure how to get the exterior ss off to remove the spray foam. Once I clear this hurdle I have tons of questions. What does PID stand for? Electric or propane? I have only been smoking for 2 years on a smokey mountain vertical smoker so I am used to propane but not stuck on it. I was thinking of inclosing the bottom where the compressor was and housing the heat source, chip pan? and water tray. I see on SMF that alot of these builds use smoke machines (my word) instead of chips or dust. Advantages/disadvantage? I was thinking I would use the ss floor of the fridge and drill a bunch of holes in it as a baffle. good or bad idea? Here are a couple pics, any and all advise will be greatly appreciated. Thanks in advance. Alright it won't let me post pics because I haven't been successful verifying my email. First things first and then I will put up pics.
