Until now the only furnace we have been able to offer that will melt cast iron has been Dave Gingery’s gas fired crucible furnace which, whilst a superb design of which a fair few have been made, only melts small amounts of cast iron. NOW you can melt much larger quantities, thanks to Steve Chastain who has written this brilliant book, highly recommended by Dave himself. The 10” diameter, 7’ high cupola Steve describes in detail here will melt 330 pounds of iron per hour in its standard version, or 660 pounds per hour in the supercharged (or blown) version! This is really a very good book; the design is explained clearly - as is the maths behind it, so you can vary the size if you want. This is information you won’t find anywhere else in such concise form, and if you build your own cupola, you can save a fortune on buying castings. I am not sure what your neighbours are going to say when you fire up this brute, but that is your problem. 124 page paperback, published by the author, with drawings, photos, tables and all you need to know.
