It is a plumber's furnace. Get a big iron pot and use it to clean up your scrap lead. I melt a bunch of wheel weights at one time and to get a uniform mix, skimming off the steel clamps and miscellaneous floating crud. It will melt big batches more quickly than an electric one. Mine is made for white gas, but I've used unleaded, kerosene, and even Stoddard solvent in it. When using kerosene or solvent you might have to warm up the generator part that sits in the flame, before you get a good vapor output. The generator takes the liquid fuel which comes in under pressure from the tank, and boils it to a vapor, and shoots it through a tiny hole, making a jet which pulls in air to keep the flame blue. A small propane torch can warm up the generator when using the 'wrong' fuel :wink:
If it is a gasoline generator, it will have a little metal or cast iron tray below the burner. You are supposed to pump up the tank and carefully dribble a little gasoline from the jet onto this tray. If you open up the valve all the way, it will go into the air and onto you. You the shut OFF the gasoline and carefully light the tray. These were made in the old days, when stupidity was supposed to hurt, so be careful. After the tray burns for a while, the generator will warm up enough to boil some off the gasoline coming out of the small hole, and you can slowly open the valve and throttle up. If it spits gas and the flame is still white and sooty, it's not hot enough, or the pressure in the tank is low. When it's hot and the pressure is high enough, the flame will be pure blue and have a nice roar to it. Keep the leather in the pump oiled. Chances are it's dried out and useless, but oil it anyway. The other common problem is crud getting into the orifice in the burner. I use a piece of wire from an old steel cable to poke it. It is a very small hole, so don't make it too big. Using kerosene or solvent is just a matter of getting it hot when you light it, it burns the same. If the tank is rusty on the inside you are SOL :cry: as the flakes of rust will continually block the generator and orifice. You would have to take the whole thing apart to clean it up. Good luck.
