Moving back to the point:
I have been warned that aluminium is NOT safe. Honestly - I have no idea what exactly could happen when an aluminium flex duct is used, though one of the forum members has warned me not to use it. I realise that beer cans, scout billys and so on are made (mainly) using aluminium. Still - it is not pure aluminium, right?atcNick wrote:I know galvenized metal is not safe around food.

Here is my smoker. The smoke goes through a flex duct about 10 feet long. Once again: I have been warned that it may be not safe.
The duct is not heat resistant - we (my dad and I) have managed to burn a hole in it, right after the stove.
And here is my very first cardboard box/soldering iron smoker
