Waste oil drip stove

Here is a small heater I made out of scrap metal. It works surprisingly well, for what it is. A little fiddly to get going, but once warmed up, it will chooch along until it runs out of fuel. I plan on doing a temperature analysis from frozey, to cozy in the near future. I should probably rig up a junkyard fan to improve airflow, and heat transfer. I also have an idea to maybe run the cold stove off a more volatile fuel, such as diesel. That way I can introduce the oil to an already hot brake drum.
