yeah, the reason behind using what I did was durability, figured I wouldn't need to worry about it falling apart and big bonus, cost me nothing to have made...I tend to be cheap when starting a new hobby, still kicking around the mini smoker/ bbq pit idea. I could increase the internal volume a significant amount by going to 1" of wool, coat with satinite, topcoat with Plistix, and hard firebrick in the bottom.
