I just found an old fridge on of my co-workers wanted to get rid of (it didn't work). Took it home, gutted it and took all plastic and insulation off, basically everything came off and I was left with the shell and doors. I tipped the fridge upside down, I rehung the doors with hinges so that the doors closed tighter since there was no seal. I then cut an old piece of tin to put down towards the bottom so that I could have a firebox in the bottom where I put hot coals from my outdoor furnace and some fresh cut maple (for good smoke) Since it wasn't airtight and the firebix wasn't real tight the smoke works it's way up through the meat. I'm not sure how to put pictures on with this message so I might have to post a new thread with some pictures. If you know how I can post them in this thread, let me know and I'll do that instead!
