I acquired a food warmer and want to convert it to a vertical smoker kind of UDS style. I'm thinking charcoal basket with chunks with a full size sheet pan as a diffuser. Exhaust i'm thinking 2 2" nipples.( this is what I have) Intake I was thinking of cutting a hole in the door a making a slide gate. What do you think? Do you have any Ideas I could incorporate? Any idas will be greatly appreciated.
