Thanks for the responses guys. Scooter, looking at the pics of your Reefer Madness, is like looking at q porn. It is so awesome it's sick!
I have a 20 year old upright freezer that went crapola about a month ago. It is simply not worth fixing and my wife has her eye on a new one. Other than not working, it is in good condition. No scratches, or dents or other blemishes on it. I would like to make it into something useful rather than just taking it to the dump. I saw you ingenious folks converting the stuff into smokers. Well I have a cheap propane grill that is down to one burner and it has more rust than paint, so I need something else. Don't much care for propane, I have never been very good at it. I have always had a lot of luck and fun with charcoal and wood chunks. Never used any pellets so I really do not know how they are or how they work. I have a small water smoker that is more frustrating than useful. It has a small bowl that holds the fire and the cooking section is barley large enough for a small chicken. I was looking at the UDS and noticed that some of them were using small fire boxes from Lowes. I think that it is an option for one of their grills.
I was thinking that how small the SFB is compared to the volume of the freezer, then having too much heat would not really be a problem, but I'm just guessing. I was thinking about stripping the freezer down to basically the metal shell, and building off of that. Something like and internal frame or lining it with SS and doing all of the other conversion stuff to it.
Figured that since I need something new to cook with, I could invest the money into converting the freezer and having something custom built to my liking. Plus it could be a nice project for me and the kids.
