Multi use tank Because of the length of this post I well break it up and distribute the pictures amongst them. I built this tank from 2 army-cooking pots that were given to me after using the forklift to unload heavy items and pallets after the army camp down sized and tore down some buildings. Surplus Herbyâ€™s bought every thing and had an army surplus sale. Spotted these 2 nice big pots and the design formed in my head that they would make a very good multi use double boiler. He asked what I wanted for unloading with the forklift and II countered with what do you want for those to pots. Deal Done. Best 15 minuteâ€™s worth of my time.
