we can take anything out of the scrap pile we want. ours is not really a pile, but in a roll-off from the local recycler. i built my current smoker at work, with stuff from work, but not all of it came from the scrap "pile". i did buy some of it, ie thermometers, firebox, door hinges. i did not get to cut the drums, and they might be gone by next weekend. if they are there i am grabbing them.
