DBgenerator;
Take a gander over on pepas diary. He's got quite the setup. In fact, at the end of May I plan on making an extended visit to take copious notes a pictures of his setup to answer several questions. Enquirying minds want to know:--)
Drop him a note he's very forth coming about his setup:-) never mind the fact that he's got about 1,000 gals of oil all setup and ready for next winter:-)
Also , there is the Mother Earth News archives , go to thier website and find the archive are and type in, waste oil burner, they did tons of stuff, then there's also journey to forever's website, they seem to have gotten building these down to a science.
Hope this helps!!
