Went out and got the majority of my parts today.
Lowes had 0 Expanded Metal and Home Depot only had square size. Going to try Ace tomorrow.
EDIT. Why not mix some beer making equipment left overs with the new smoker build.
I have a 15 gallon stock pot that came with a basket. It's pretty heavy gauge aluminum and already comes with a built in handle. Could I use this instead of trying to make a basket from expanded or will the direct heat from the coals and destroy it in a matter of months? (I don't care if it survives, I've never used the basket for anything.)
