obviously you don't weld,which in itself is not a crime,if it were i would have been jailed year's ago,if your wanting to build your own smoker,please take a welding class or two and learn the basic's of this fine trade before you decide to invest in a piece of equipment you will never use or utilize once you find out it's not that easy,seriously,take a class you'll be glad you did,and you will be proud of your build.
