This well written and understandable little book will introduce you to capabilities you may think are completely out of reach. Now you can make your own reproduction castings. Along with many other items, I've cast 2 different tail stocks, and some horizontal mill parts. The book tells how to design and build a coke-fueled cupola furnace, blown by a cheap used vacuum cleaner, and capable of producing 60 lbs. If you care to build the high pressure blower also described in the book, you can produce as much as 600 lbs of this fabulously hot and magic liquid per hour.
Bronze is equally easy to do.
It ain't rocket science, as they say. What it really is, is age-old technology explained for the guy who wants to be able to make, in his own back yard, castings he can't buy. This book deals only with the matter of building a furnace. It does not tell you how to choose and mix molding sand, make molds, and other aspects of home foundry work. There are other books that deal with those topics.
