I am a teacher at a school and they were going to get rid of an old food warmer It is insulated and has places for lots of racks. The element in the bottom is shot. I was thinking that it would make a perfect smoker. It needs some work to be convereted. Then I though, what else is insulted and has a heating element in the bottom? An Oven! Why not just take an old gas or electic oven and cut a couple holes for venting? Place a chip pan at the bottom and you are good to go. Glass door, adjutable racks, constant temps, built in workspace on the top. It seems like it would be a perfect smoker. You can find used ovens on craigslist for under $100. Is that just too easy, or is it just cheating?
