Perhaps the easiest way of mounting the top 2 inches of a Weber kettle base to the top of a drum is with red silicone.
Personally, this is the last method I would use as it just looks kind of crude to me. Not as bad as hammering out a Weber lid to fit a drum though.
My apologies to those who used either of these methods.
As for expanded steel. previous reports were that ACE hardware had better prices.
