Here is another model that I built this winter. Propane vaporizers are used by companies that do not have ready access to natural gas that they use in their manufacturing processes. I'm not sure how the process works but, I like the look of the machinery so I built it. The tank is made from a discarded aroma beads bottle and the bottoms of aluminum soda cans. By carefully trimming the aluminum, I was able to snap fit the parts together!! I made a simple fixture to make the pipe fittings. Here are some photos:
