I've got one of the cheapo Master Forge double door units from Lowes. Had it a few years and done some mods to it and love smoking with it. Not ready to trash it but the bottom is rusting out. I want to put a sheet of metal or something in the bottom and just put a new burner in and still smoke with her. Any thoughts on what I could use in the bottom? Some sort of sheet metal? Also any ideas on burners? Regardless of what I get, I'm getting a needle valve. Thanks for any advice. ETA: I also just got an amazing pellet smoker from Todd and want to add a mailbox mod for it. So I got to save this old girl!
