Step 9: Foundry tools, Ingots and clip.
I made some tools for my old furnace and they are still good for this one. To get rid of the dross I used a big spoon with holes as a dross skimmer. I'm starting my first melt with charcoals and in the near future I hope to make a waste oil burner.
After the charcoals where red I checked the temp with my multimiter and it showed over 1000�igh temperature.
My first successful melt were parts of an aluminum ladder, I used my muffin tray to cast the aluminum ingot.
The second time I used the pot it broke under the heat and all the molten aluminumn spilled out. Not too bad news It could have been much worse if it happend when I lifted the crucible.
Now I just have to chop the chunks of aluminum and throw them back into a new and much thicker cruicible made from metal pipe and steel plate.
This is a short clip of my furnace in full action...
