Someone in the know please chime in.
I would agree on this too. One question, are the galvanized pieces on the inside or outside of the drum? Are they galvanized pipe that threads into the holes? Reason I'm asking, air passing through the galvanize into the drum shouldn't hurt as long as the galvanize isn't heating up enough to emit fumes. If they are outside the drum & below the heat, I can't see how a few very small pieces could be a problem but I'm no expert.
