I made a new casting furnace to go with my new forge. In this video the new furnace is used to melt aluminium scrap into ingots and muffins. These will be used in upcoming videos to cast various items. Casting the scrap into bars allows it to be cleaned up so that items made from these bars will be of good quality.
The furnace is made from a 5 gallon steel pail lined with firebrick and refractory cement. The burner is a forced air type. The blower came from an old microwave oven and its speed is controlled by a variac. The crucible is a piece of steel pipe with a bottom made from steel plate welded on.
