Step 1: Burner V1.0
I used a axcetelyne tip for the oil injector, it seems to make a fine enouph spray at arround 50 psi in the fuel tank.
I first tried a simple high voltage supply for the ignition source, made with a rehostat and a ignition coil, this proved to not be a hot enough spark. Next i tried two ignition coils in tandum, this made a more stable spark but still wasn't hot enouph.
I have aquired a Neon sign transformer, and if that doesn't work I have a rewound mercurey yard lamp ballast that I was planning to use in a welder project.
Step 2: Oil burner retro-fit
I have salvaged a Heating oil burner form an old furnace and am in the process of modifying it for the foundry project. This is another option for those who don't have a welder or just want to skip to the fun stuff.
Step 3: The sand Bed
This is what I made up for doing open face molds, and its a place to set the crucible after a melt for it to cool.
