I have been a member here for a few years. Some may recall my current smoker the "Reverse flow flop" thread, which I modified and love using. Today I started a build for a friend of mine. Local scrap metal place had used air compressor tanks for $40, so I thought what the heck!! The one I chose is 3/16" thick which will be sufficient for what he's gonna use it for. Today I brought it home, cut the motor mounts off and removed the legs. The new plasma torch did a fantastic job at that. Then I cut the door out with a cutting wheel. I also filled in one of the small holes and ground it smooth. Used the plasma to cut out some large fittings on the ends. I'm really fascinated by this tool!! Interior of the tank had virtually no rust and the few places it did are only superficial. Dimensions of the tank are 46" by 27" diameter with a circumference of 75" I believe. Tomorrow I hope to round up some square tubing and expanded metal for the frame and shelves, while I wait on Dave to look over my measurements and set me straight with firebox dimensions. Any and all comments or suggestions are appreciated!!
