Mad Jack, Here is a link to a thread that got me started. I did the basic mods to the touch up gun from this concept. http://www.backyardmetalcasting.com/forums/viewtopic.php?t=3341&highlight=waste+oil |

I think it will make a fine burner, and get some metal melted. Thanks much for that link and I'll let you see what I get as a result of playing around with sprayers and fire. I knew keeping that waste oil tank was a good idea, it's been ten years or more and there's got to be a couple hundred gallons of waste oil in it, free. If I ever empty it, I can use my smaller tank, and use the larger one to build a good solid gun safe, I need one, and they're expensive, almost more than guns themselves. Top shelf, Gadget, top shelf!! :thumbup: :thumbup: :thumbup:mad jack |

Mad Jack, I suggest building a pressure tank for the oil, no preheat needed that way. Also, once the furnace has reached a good temp you can shut the air pressure off the air line and just let the tank pressure feed oil out the burner. I run mine at 40 to 50PSI and it works well. I always leave a pound or two of air pressure on the air feed line to keep the oil from backing up in the gun. When lighting, I put an oily paper rag or towel in the furnace, light it with a butane torch, turn the air pressure to about 30 on the air inlet and use the fine spray adjustment on the gun to start feeding the oil mist. Close the furnace and allow it to get hot. Once the unit is hot enough to keep the flame going well you can turn the air blower on and put the crucible in and start feeding metal. One caution, anytime you open the furnace wear a face shield. The oil fire tends to flare up when the furnace gets opened. Lost an eyebrow or two finding that out myself. Dan |

Here is a brief video of the furnace in operation. This was taken before I got a permanent blower but the unit still works the same now. "&hl |
