    Default The "pores" of the metal -

    OK, try this one -
    I've seen a lot of posts on other sites warning the folks building smokers out of drums that they should only use "food grade" drums because the toxic whatever that was in the drum "is still in the pores of the metal" and will either poison the food cooked in it or make you have kids with 3 legs or something.
    So, I called my son down in Ft. Lauderdale. His degree is in metalurgy and powdered metal technology. He tells me -
    The drums are made from cold rolled steel, and it DOES NOT have "pores".
    Cast iron is somewhat porous. But steel is not and will not retain any chemicals.
    So make sure you clean and burn your drum (or propane tank) out really well before making your smoker. And enjoy.
    Ok, go for it -

    I will check this with an engineer at work (who is a metalurigist <sp?>) and see what he says. Remember, I work at Alcoa Fastening Systems- we make "rivets" for industrial apps. Everything from a pop rivet to a pin that is 1" in diameter by 4- foot long. I trust you Mike, just want to get a second opinion. Hopefully I will be backing you up.

    No smoke blowing here.
    The kid really does have the degree (I know, I paid for it).
    Thanks for the backup Chris!

    No problem, Mike. Where did he get his degree from? The guy at work got his at the University of OK.

    The big difference is "food grade" drums are a better guage metal. I would personally do a good burn with the drum before use. The catalogs I have for drum makers state they have two different linings, rust-proof or resin coated.

    Yep, a good burn out is the deal, regardless. I would burn out a new drum.
    "Food grade" drums are coated inside to resist corrosion from the substances shipped in them. A thorough burn out is necessary to remove that coating.
    The issue addressed is folks thinking there are "pores" in the metal that would somehow hold residue from whatever was in the drum, food products, Diesel fuel, hydrotoxic sulfuric benzoslime, or whatever.
    That simply is NOT the case. There are NO "pores" in steel.
    I got pores, you got pores, pigs got pores, steel ain't got no pores!
