How could I make an igniter for a waste oil furnace/foundry? Answered


I am making a waste oil furnace/foundry and don't want to have to use charcoal to ignite it everytime, so I am thinking of buying a 15000 volt neon sign transformer and using nails or tungsten TIG electrodes to ignite it. Would this work? I can't find any places near me which sell tungsten TIG electrodes? I was worried about using nails because I think they might melt from the tempature of the flame. Is that true?

I just thought maybe i could use two old sparkplugs and only use one of the two electrode pieces on each one, this will make it so i can a larger distance between the electrodes.
